SECTION 1

INTRODUCTION

1.1 PURPOSE.

This Technical Order (TO) contains the methods and procedures for the management of the Air Force Metrology and Calibration (AFMETCAL) Program. This TO implements AFI 21-113, Air Force Metrology and Calibration (AFMETCAL) Management.

1.2 GENERAL.

The AFMETCAL Program is an Air Force program that provides measurement standards and equipment, professional and technical metrologists, performing work centers (PWCs), a system of worldwide Precision Measurement Equipment Laboratory (PMEL) facilities, measurement equipment users, calibration data and integrated planning. This program ensures the reliability and accuracy of systems, subsystems and equipment. The program provides for the calibration and repair of Test, Measurement and Diagnostic Equipment (TMDE). It also ensures measurement traceability of the TMDE through the Air Force Primary Standards Laboratory (AFPSL) to National Institute of Standards and Technology (NIST) or other AFLCMC/WNM (AFMETCAL) approved sources. To accomplish this traceability, the AFMETCAL program requires that Air Force users and Precision Measurement Equipment Laboratories (PMELs) obtain calibration service from Air Force PMELs or the AFPSL. AFMETCAL must approve calibration service from other sources. The responsibilities of organizations in the AFMETCAL Program are identified in AFI 21-113.

1.2.1 AFLCMC/WNM (AFMETCAL). AFLCMC/WNM, referred to as AFMETCAL throughout this document, serves as the Air Force technical authority on metrology issues and is the Air Force single point of contact for calibration services and traceability of measurements to NIST. AFMETCAL makes TMDE calibration and repair responsibility determinations. AFMETCAL publishes responsibility determinations in TO 33K-1-100-1 and TO 33K-1-100-2 and Calibration and Measurement Summary (CMS) TOs. TO 33K-1-100-2 and the workload summary tables in the CMS TOs are electronic data tables displayable with the Air Force Calibration Authority Viewer (AFCAV) application included with these TOs. The PMEL Automated Management System (PAMS), Facility and Equipment Maintenance System (FEMS) and LabMet systems maintain authorized facsimiles of TO 33K-1-100-2 and certain CMS workload summary tables. All references to TO 33K-1-100-2 and CMS TOs apply equally to the corresponding authorized electronic facsimiles maintained in PAMS, FEMS and LabMet. If specifications are listed as “Table 1” in TO 33K-1-100- 2, they must be used and can only be viewed using AFCAV. The AFMETCAL Point of Contact (POC) list is available on the Metrology & Calibration Functional Area of the AF Portal. This POC list should be used to determine the appropriate AFMETCAL personnel/office to be contacted for specific issues addressed by this TO.

1.2.1.1 Key documents referenced above:

a. TO 33K-1-100-1 (Calibration Procedure for Maintenance Data Collection Codes And Calibration Measurement Summaries)

b. TO 33K-1-100-2 (TMDE Calibration Notes, Calibration Interval, Technical Order, And Work Unit Code Reference Guide)

1.2.1.2 Calibration Repair Network. The AFMETCAL Program has been recognized as a Calibration Repair Network under the Repair Network Integration (RNI) initiative. Under RNI, the AFMETCAL Director is also known as the Product Repair Manager, AFMETCAL’s Plans and Analysis Section is the Repair Network Manager, the PMEL MAJCOM Functional Managers (MFM) serve as the MAJCOM leads, and PMEL Managers are referred to as Node Managers.

1.2.2 Air Force Primary Standards Laboratory (AFPSL). The Air Force Primary Standards Laboratory (AFPSL) maintains the Air Force Measurement Standards. The standards are traceable to NIST or other sources as approved by AFMETCAL. Air Force Measurement Standards are used to ensure the accuracy and traceability of Base Measurement Standards. Base Measurement Standards are provided to PMELs.

1.2.3 Precision Measurement Equipment Laboratories (PMELs). HAF/A4LF approves the establishment of PMELs at selected installations. The PMEL is the base-level AFMETCAL Program focal point. It is the activity authorized to

1-2 possess and use base measurement standards. Operational details of the program are set forth in Section 3 of this TO and related command directives.

1.2.4 Program Controls. Commanders of U.S. Air Force, Air Force Reserve Command and Air National Guard activities shall establish controls to ensure TMDE under their control (including Government Owned/Furnished and Leased/Borrowed equipment) is repaired, calibrated and certified. Commanders shall ensure PMEL facilities are built according to AFMAN 32-1094, Criteria for Air Force Precision Measurement Equipment Laboratory Design and Construction, and AFMAN 32-1084, Facility Requirements, and operated according to Section 8 of this TO. AFI 21-113, along with this TO, applicable CMS TOs, TO 33K-1-100-1 and TO 33K-1-100-2, and command directives prescribe those controls. TMDE in use shall be calibrated at regularly scheduled intervals called out in CMS TOs, TO 33K-1-100-1 and TO 33K-1-100-2. Authorized exceptions to calibration are identified in Section 3 of this TO, any applicable CMSs, and TO 33K-1-100-2.

1.2.5 Other DoD Services Calibration Laboratories. The use of other DoD services calibration laboratories is authorized when approved by the applicable MFM and AFMETCAL. The Army, Navy and Marine Corps operate calibration laboratories using similar measurement techniques and management concepts. These laboratories provide measurement traceability to NIST. Units requesting support from another service shall follow the guidance in Section 4, which includes the interservice support agreement guidance.

1.3 SCOPE.

This TO applies to all activities that possess, use, calibrate, certify or maintain TMDE.

1.4 DEFINITIONS.

The following definitions apply for the purpose of this TO.

1.4.1 Absolute Measurement Standard. Designated measurement standards based on the absolute value of natural physical constants whose values can be accurately repeated under controlled conditions. Also known as an Intrinsic Standard. Examples are Laser Length Standards, Josephson Junction Voltage Standards and Hall Effect Magnetic Field Standards.

1.4.2 Air Force Primary Standards Laboratory (AFPSL). The highest-level laboratory in the AFMETCAL Program. It maintains Air Force measurement standards certified by the NIST, the US Naval Observatory (USNO), or other AFMETCAL approved sources.

1.4.3 Calibration. Calibration is a comparison between equipment items, one of which is a measurement standard of known accuracy, to detect, correlate, adjust and report any variation in the accuracy of the other item(s).

1.4.4 Calibration, Limited. Calibration of TMDE to less than the accuracy or functional capabilities specified in the authorized calibration procedure or data.

1.4.5 Calibration, Special. Calibration of TMDE to all specifications called for in the authorized calibration procedure plus additional requirements.

1.4.6 Calibration and Measurement Summary (CMS). A TO which identifies calibration support necessary to ensure the operational readiness of a specific weapon system, weapon subsystem or mission. The summary describes the calibration concept and is calibration authority for the applicable weapon system, weapon subsystem or mission. The CMS is printed as a weapon system or 33K series technical order. AFMETCAL maintains Air Force CMSs (see paragraph 2.4.3).

1.4.7 Calibration and Measurement Requirement Summary (CMRS). Three category, in-line summary of measurement parameters. Normally, a Program Office or Department of Defense (DoD) system contractor prepares and maintains the CMRS (DI-QCIC-80278B). A CMRS identifies all measurement requirements within a specific system or item of equipment. The CMRS further displays the proposed solutions for maintaining the system measurement requirements within stated limits. It is also used to identify the need for new calibration standards. This data is provided to AFMETCAL, 813 Irving-Wick Dr W, Bldg 2, Heath OH, 43056-1199. AFMETCAL uses it for ensuring calibration supportability and planning for PMEL support for a particular weapon system/subsystem (see paragraph 2.4.2).

1-3

1.4.8 Calibration Certificate or Calibration Report. Also referred to as, "Report of Measurement". It is a document containing data relevant to the calibration of a specific test instrument or standard. The AFMETCAL Program does not differentiate between a calibration certificate and a calibration report provided the document contains the required information to interpret the calibration results for the specific calibration.

1.4.9 Calibration Chart. A chart prepared for a specific item. It shows the difference between the nominal value and the actual value of a measurement or group of measurements.

1.4.10 Centralized Repair Facility (CRF). Centralized repair facilities provide regional intermediate-level maintenance repair support for designated USAF units. This regional repair capability replaces the decentralized maintenance concept in which base-level units performed all intermediate-level maintenance for deployed aircraft.

1.4.11 Certification. The documented designation that standards and TMDE have been calibrated and meet established technical requirements.

1.4.12 Commercial Calibration. Calibration of TMDE obtained from a commercial source where the TMDE already has a published calibration determination but the calibrating activity (PMEL or USER) asks for an exception. This should be considered only after organic (Air Force) support options have been exhausted. AFMETCAL approval is required prior to obtaining the commercial calibration from a commercial source. Commercial calibrations will be funded by the user.

1.4.13 Contingency Calibration Operation. A deployed calibration capability that may include but is not limited to Rapid Assistance Support for Calibration (RASCAL), Transportable Field Calibration Unit (TFCU), mobile calibration teams, combined operations with a foreign military, etc. See Figure 1-1 for the PMEL support matrix.

4. CRF and PMEL as applicable shall use the customer’s AF Form 616 Fund Cite Authorization to fund repair parts (Ref: AFI 21-101).

Figure 1-1. PMEL Support Matrix.

1.4.14 Contract Calibration. Calibration obtained from a contracted source, funded by the user or an Item/Program Manager. Neither the PMEL nor AFMETCAL centrally manages or funds these calibrations. These items are identified with a calibration responsibility of “CONTRACT”.

1.4.15 Correction Chart. A chart prepared for a specific item. The chart shows corrections to apply to indicated values to obtain true value. In instances where an item is charted and the item’s accuracy or uncertainty is applied, the charted values can be used through the item’s calibration interval. However, in instances where a better accuracy or uncertainty

1-4 of another standard is “transferred” and being used, the charted values may only be used to complete the immediate calibration requiring the transfer/charting. The AFPSL is authorized to assign an interval only after a documented engineering analysis is completed that supports the transfer of accuracy or uncertainty to the assigned interval.

1.4.16 Equipment Types:

a. Mission Equipment. Part of operational ground or airborne systems.

b. Non-TMDE. SE not meeting the TMDE definition. This equipment does not require calibration and is the responsibility of the user.

c. Precision Measurement Equipment (PME). For purposes of this TO, PME is the same as TMDE. This is the former title for TMDE.

d. Support Equipment (SE). A broad category of equipment and tools used to verify and maintain mission equipment. Support equipment can include equipment used to verify the operation of other support equipment.

SE is categorized as either TMDE or Non-TMDE. The AFMETCAL Program is primarily concerned with TMDE support equipment.

e. Test, Measurement and Diagnostic Equipment (TMDE). Devices used to maintain, evaluate, measure, calibrate, test, inspect, diagnose or otherwise examine materials, supplies, equipment and systems to identify or isolate actual or potential malfunction, or decide if they meet operational specifications established in technical documents. ISO 17025 refers to this equipment as “measuring and test equipment.”

1.4.17 ISO/IEC Standard 17025. The international standard for commercial metrology, “General Requirements for the Competence of Calibration and Testing Laboratories.” It includes the relevant requirements of ISO 9000 series standards.

The AFMETCAL program does not approve this standard as the sole requirement for operating a USAF PMEL.

1.4.18 Manager. The individual responsible for day-to-day management and operation of the PMEL and its associated work centers, such as production control, quality program and material control. Synonymous with PMEL superintendent, PMEL branch chief, TMDE branch chief, TMDE flight chief, TMDE section chief and Laboratory Manager. The PMEL Manager is referred to as the PMEL node manager under RNI.

1.4.19 Measurement or Reference Standards. Equipment by which the accuracy and traceability of a precision measurement is derived. The typical chain of measurement standards is shown in Figure 1-2. The following are types of standards:

a. Air Force Measurement Standards. Equipment certified by NIST or other AFMETCAL approved sources.

These standards are used by the AFPSL as a basic measurement reference for the Air Force.

b. Air Force Primary Standards Laboratory (AFPSL) Working Standards. TMDE certified by the AFPSL and used to calibrate other TMDE.

c. Base Measurement Standards. Equipment certified by the AFPSL or AFMETCAL approved sources. These standards are used by an Air Force PMEL as a measurement reference. Base Measurement Standards are designated in TO 33K-1-100-2.

d. Exchange Standard. A calibration standard calibrated by the AFPSL through a calibrate and replace methodology to minimize PMEL down time. An exchange standard is calibrated by the AFPSL and sent to a PMEL to replace a like base measurement standard before its calibration has expired. The exchange standard whose calibration interval is expiring is returned to the AFPSL for calibration, and then forwarded to another PMEL. TO 33K-2-11, Detailed Instruction and Information Pertaining to Air Force Primary Standards, Laboratory Calibration Exchange Standards, and Artifact Proficiency Testing Standards, PMELs Only, contains detailed instructions and information for Exchange Standards.

e. National Measurement Standards. Equipment or physical constants identified and normally used by NIST.

These standards serve as a basic measurement reference for use throughout the United States and at U.S.

installations/activities overseas.

f. Working Standards. TMDE certified by PMEL and used to calibrate other TMDE.

g. Transfer Standard. A measurement standard calibrated by the AFPSL and circulated to multiple PMELs to calibrate base measurement standards or working standards. A transfer standard is calibrated by the AFPSL, forwarded to a PMEL, used by the PMEL to calibrate a base or working standard, and returned to the AFPSL or forwarded to the next PMEL as directed. TO 33K-2-11 contains detailed instructions and information for Transfer Standards.

1.4.20 Metrology. The science or system of weights and measures used to determine conformance to technical requirements. This includes the development of standards and systems for absolute and relative measurements.

1.4.21 Precision Measurement Equipment Laboratory (PMEL). A laboratory authorized to own and use base measurement standards to maintain working standards. The working standards are used along with PMEL-owned TMDE to maintain (troubleshoot, align, repair, and calibrate) TMDE designated as PMEL responsibility. Authorizations for PMEL equipment and facility requirements are tailored to meet specific requirements for supported missions. PMELs are the base-level link for measurement transfer and maintenance self-sufficiency for all systems in the Air Force. PMEL types are:

a. Type IIA. A base-level PMEL with a 68°F room providing support to an Air Logistics Complex (ALC) and/or a large geographical area. ALC PMELs are operated by AFMC. PACAF theater support command operates the Type IIA PMELs at Kadena AB, JA and Elmendorf AFB, AK. USAFE theater support command operates the Type IIA PMEL at RAF Feltwell, UK.

b. Type IIB. A base-level PMEL established to support aircraft, missiles, ground systems and/or other equipment on base or in the local area.

c. Type IIC. A base-level PMEL with a 68°F room supporting research, development, test or evaluation programs, as well as other operational and support functions.

d. Type III. A PMEL supporting a specific mission. It normally receives calibration support from a Type II( ) PMEL. With the exception of Rapid Assistance Support for Calibration (RASCAL) sets, a Type III PMEL is not authorized at an installation where a Type II( ) PMEL exists.

1-6

e. Type IV. A PMEL supporting a specific weapon system. It uses a transportable measurement system in fixed and deployed locations. A Type IV PMEL receives calibration support from a Type II( ) PMEL. It may be located at an installation where a Type II( ) PMEL exists. Type IV PMELs are no longer authorized in the USAF metrology program. They still exist, however, in FMS country metrology programs.

1.4.22 PMEL Mobile and On-Site Measurement Capabilities.

a. Rapid Assistance Support for Calibration (RASCAL). A portable PMEL designed for rapid deployment to support emergency calibration needs. It consists of five environmentally controlled shelters containing measurement standards and other TMDE. The shelters are joined together when in use. They are taken apart and airlifted to the needed location.

b. Jet Engine Test Stand Calibrator (JETSC). TMDE and accessories needed to perform on-site calibration of jet engine test stands, housed in a trailer or set of ruggedized cases.

c. Portable Automatic Test Equipment Calibrator (PATEC). A PATEC is used to calibrate Automatic Test Equipment (ATE) on site. A PATEC consists of a set of portable standards. A Core PATEC meets the calibration needs of a variety of test stations.

d. Transportable Field Calibration Unit (TFCU). The TFCU consists of working standards in hardened cases selected to function within given performance tolerances as long as the equipment is operated within the published environmental restrictions of the TFCU. The TFCU is used to calibrate TMDE located at remote sites or bases.

1.4.23 PMEL Quality Assurance (PQA) Evaluator. Shall be a highly qualified 2P071 or equivalent when possible.

PQA evaluators are selected by PMEL management and appointed in writing. PQA evaluators are the only personnel designated to perform Quality Reviews and Process Reviews applicable to the Quality Program.

1.4.24 Proficiency Testing/Measurement Assurance Program (PT/MAP). The PT/MAP is a process for assessing laboratory capability by means of inter-laboratory data comparisons and exchange standard intercomparisons. Results from PT/MAP are an indication of a laboratory’s competence and are an integral part of the assessment process.

1.4.25 Rainbowed Equipment. Non-prepositioned equipment that is sourced from multiple units, left in place, and used by multiple units over time to enable the best support of vulnerable AEFs while minimizing home station impact on supporting units.

1.4.26 Reachback. The process of obtaining products, services and applications of forces, equipment or materiel from Air Force organizations not forward deployed. This capability allows commanders to obtain or coordinate support from units not physically located with the forward force. See AFI 21-101 for more information.

1.4.27 Shall. Shall is a directive statement. Reference TO 00-5-1, AF Technical Order System.

1.4.28 Test Accuracy Ratio/Test Uncertainty Ratio (TAR/TUR). The ratio of the uncertainty (accuracy) of the TI to the uncertainty (accuracy) of the standard (for example 4:1). TAR and TUR are equivalent in the Air Force Metrology and Calibration Program, as the term Accuracy has been used for the (more correct) term Uncertainty in Air Force Calibration procedures.

1.4.29 Traceability. The property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty. Mandatory USAF traceability relates individual measurement results to national standards at NIST or AFMETCAL-approved sources through an unbroken chain of calibrations all having stated uncertainties as shown in Figure 1-2.

1.4.30 User. User refers to the using activity or owning organization responsible for calibration and maintenance of items designated “USER” responsibility in a CMS or TO 33K-1-100-2. In most cases, the ‘user’ and the ‘owner’ are the same. In general, the ‘user’ is the activity that physically uses the item. The ‘owner’ is the organization that owns the item via a supply account. The 'user' performs USER calibrations or coordinates with the PMEL for assistance when resources are not available. The PMEL will assist to identify required equipment or approved sources of support. As a last resort, the PMEL may perform the calibration. The owner is responsible for all funding associated with these efforts.

SECTION 2

AFMETCAL PROGRAM ORGANIZATION AND INTERFACE

2.1 GENERAL.

The AFMETCAL Program includes AFMETCAL, PMELs and their resources, and the TMDE in the Air Force. The directives that provide the policy and guidance are also part of the program. The purpose of the AFMETCAL Program is to ensure that all Air Force TMDE used to make measurements is accurate, reliable, provides standardized measurements, and is traceable through the AFPSL to NIST or other AFMETCAL approved sources. This TMDE is used to make sure that each system and subsystem is accurate and reliable and ensures that they properly interface with other systems.

2.2 AFMETCAL PROGRAM.

2.2.1 Figure 2-1 Description. Figure 2-1 depicts each element of the AFMETCAL Program and the interrelationship of major Air Force organizations. The center circle identifies the major elements of the AFMETCAL Program:

AFMETCAL Director (AFLCMC/WNM), the PMELs and TMDE users. The focus of the AFMETCAL Program is to ensure accuracy and traceability of TMDE. This TMDE is used to ensure the accuracy and reliability of all Air Force systems. The resources needed to operate the AFMETCAL Program are identified in the rectangles. In cooperation with the other elements, AFMETCAL provides program guidance, PMEL standards, traceability of standards, calibration procedures, PMEL evaluations, metrology engineering support, and determines calibration requirements of systems. The PMELs are the performing work centers containing the personnel that calibrate, certify and repair the TMDE owned and used by Air Force organizations. The AFMETCAL program requires users and PMELs to obtain calibration service from Air Force PMELs or the AFPSL as appropriate. AFMETCAL must approve obtaining calibration service from other sources. The users of TMDE utilize their PMEL calibrated items to verify their support equipment (test benches, simulators, etc.) as well as major systems or subsystems. Users of the TMDE are assigned owning work center (OWC) codes.

2.2.2 Resources used by AFMETCAL Program. There are four primary groups of resources used by the AFMETCAL Program to do its mission (personnel, equipment/material, documentation and facilities). A basic need is sufficient personnel, having the necessary education, training, technical knowledge and experience for their assigned functions.

These personnel require directives/procedures, material, and facilities. Calibration procedures provide the calibration methods. The PMEL requires parts and material to perform calibration and repair of TMDE. They also need their own measurement standards. The PMEL facility has some special requirements based on the system(s) it supports. The requirements of the program are based upon the measurement needs, and the accuracy of the measurements required of all systems supported by the Air Force. The outer ring of Figure 2-1 identifies the organizations that interface with the AFMETCAL Program. They provide, or coordinate, in the provisioning of the resources for the program. The outer ring of Figure 2-1 also shows the planning required to ensure that the proper AFMETCAL Program support is available. That support is needed for all systems from the time a system is under development through its entire life cycle.

2.2.3 Funding. Material and personnel needs are satisfied according to the amount of funding available.

2.2.3.1 Funds for daily operating expenses of the PMELs are provided by the owning command. They generally come from operation and maintenance (O&M) appropriations. Business operating funds are furnished for AFMC by the MAJCOMs for the depot-supported workloads. Air Force regional workload support is generally funded by O&M appropriations.

2.2.3.2 Centrally procured investment equipment funding for equipment costing less than $250K per item is provided to the AFMC procuring agency by MAJCOMs.

2.2.3.3 Centrally procured expense (parts) item funding comes from the USAF Stock Fund.

2.2.3.4 Operating command or base procured investment and expense items are generally funded from O&M and equipment funds.

2-2

2.2.3.5 Facility funds are part of 3300 (Military Construction – Air Force) appropriations. This includes major and some minor construction projects as well as facility project planning efforts.

2.2.3.6 AFMC is responsible for funding research and development projects. This includes support required for those projects turned over to other operating commands.

2.3 PROGRAM POLICY AND DIRECTION.

HQ USAF/A4LF provides program policy in AFI 21-113, Air Force Metrology and Calibration (AFMETCAL) Management.

2.3.1 Requirements for TMDE Support from PMELs. MFMS, PMELs and TMDE user organizations shall periodically review and update war plans related to their operations. The review shall consider where, who, what and how TMDE shall be supported. Of special concern shall be TMDE that is mission essential to systems and subsystems required to meet Designed Operational Capability (DOC). This is necessary for mission capability and unit combat readiness reporting under AFI 10-201, Status of Resources and Training System.

2.3.2 Periodic Reports Utilized. AFMETCAL and the PMEL functional managers utilize periodic reports (see PMEL Reports, Section 6) submitted by each of the PMELs to assist in managing the program.

2.4 PROGRAM REQUIREMENTS.

New systems or improvements in weapon system performance are major factors in upgrading the measurement capability of supporting PMELs. AFMETCAL has the responsibility to review the measurement requirements of all Air Force systems. This normally happens through the review of Support Equipment Recommendation Data (SERD) and/or CMRS documents.

2.4.1 Support Equipment Recommendation Data (SERD). The SERD review process is used to justify the weapon system support equipment. SERDs are reviewed by Operating Commands, the acquisition agency, the item manager and AFMETCAL. Calibration responsibility determinations are made for approved SERDs. Calibration procedure requirements are established when necessary.

2.4.2 Calibration and Measurement Requirement Summary (CMRS). The CMRS documents are only required on complex systems. The completed document identifies the measurement requirements. They extend from the weapon system through the support equipment to the PMEL measurement standards.

2.4.3 Calibration and Measurement Summary (CMS). The CMS is published as a TO and details the measurement accuracy requirements on a complex system. AFMETCAL is responsible for the technical adequacy of the CMRS and the subsequently published CMS. AFMETCAL is also responsible for ensuring that measurement traceability exists from the national level to the system measurement. This includes the AFPSL capability. If the system has no unique or complex support requirements, the applicable support equipment is added to TO 33K-1-100-2.

2.4.4 Measurement Upgrade Identification. Necessary improvements in PMEL measurement capability are identified early in AFMETCAL review. This is done in the calibration responsibility determinations and the calibration procedure preparation process. If additional measurement capabilities are required, the measurement standard shall be acquired and distributed by AFMETCAL to the appropriate PMELs following coordination with MAJCOM Functionals. If only national stock listed test equipment is required; the equipment shall be added to the applicable Allowance Source Code (ASC). The equipment shall be requisitioned by the PMEL. Normally, workload summaries derived from the SERD and CMRS reviews, are distributed to the operating commands. They are distributed at various times during the life cycle of the system to allow for PMEL support planning. Since two PMELs rarely support the same type systems, very few PMELs have the exact same measurement capability. Most have the same basic capability.

2.5 PROGRAM MATERIAL.

Material is a broad category. It includes facilities as well as equipment, parts, and other items. It is used to support the AFMETCAL Program mission at all levels.

2.5.1 PMEL Establishment/Closing. Commands shall coordinate any change in the status of any PMEL with AFMETCAL and receive final approval from HQ USAF/A4LF. This includes requirements for new PMELs, elimination of any existing PMEL, or a PMEL location change.

2.5.2 PMEL Facility Requirements Documentation. AFMETCAL specifies PMEL facility requirements and performs reviews of facility project documentation. Design and construction are an owning command responsibility. AFMAN 32- 1094, Criteria for Air Force Precision Measurement Equipment Laboratory Design and Construction, AFMAN 32-1084, Facility Requirements, and AFI 32-1024, Standard Facility Requirements, are some of the major publications involved.

TO 00-20-14 (Section 8, PMEL Facility Operational Requirements) contains facility operating parameters for PMELs.
