Terms Air Force Metrology and Calibration (AFMETCAL)—Refers to measurement standards and TMDE, professional and technical metrologists, performing work centers, a system of worldwide laboratory facilities, TMDE users, calibration data, and integrated planning. The program provides for maintenance and calibration of TMDE to verify the reliability and ensure the accuracy of systems, subsystems, and equipment.

Air Force Primary Standards Laboratory (AFPSL)—The highest level calibration standards laboratory in the AFMETCAL Program. It maintains Air Force measurement standards certified by the NIST or other nationally recognized standards. The AFPSL (located at Heath, Ohio) uses these measurement standards to calibrate base level or PMEL measurement standards and equipment for Air Force customers.

Calibration—A comparison between equipment items, one of which is a measurement standard of known accuracy, to detect, correlate, adjust and report any variations in the accuracy of the other item.

Calibration and Measurement Requirement Summary (CMRS)—A three-category, in-line summary of measurement parameters. A CMRS identifies all measurement requirements within

AFI 21-113 12 November 2008 9 a specific system or item of equipment. The CMRS further displays the contractors' proposed solutions for maintaining the system measurement requirements within the stated limits. It is also used to identify the need for new calibration standards.

Calibration and Measurement Summary (CMS)—A technical order which identifies calibration support necessary to ensure the operational readiness of a specific weapon system, subsystem or mission. The summary describes the calibration concept and is the calibration authority for the applicable weapon system, weapon subsystem or mission.

Certification—The documented designation that standards and TMDE have been calibrated and meet established technical requirements. When used to refer to a calibration laboratory (PMEL or AFPSL), certification means the laboratory fulfills AFMETCAL assessment criteria.

MAJCOM (or equivalent) —This term refers to all Air Force Major Commands (MAJCOMs) and includes the Air National Guard (ANG), Field Operating Agencies (FOAs), and Direct Reporting Units (DRUs).

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.

Precision Measurement Equipment Laboratory (PMEL)—A laboratory authorized to own and use Air Force 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.

Support Equipment Recommendation Data (SERD)—A contractual data item submitted by the contractor to identify weapon system support equipment requirements.

Test, Measurement, and Diagnostic Equipment (TMDE)—Those 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 malfunctions, or decide if they meet operational specifications established in technical documents.

Traceability—The ability to relate individual measurement results to national standards or nationally accepted measurement systems through an unbroken chain of comparisons all having stated uncertainties.

Types of Standards Used in Measurement and Testing—The term "standard" means equipment or physical constants serving as the basic means by which we derive accurate and traceable precision measurements. These standards include:

a. National Measurement Standards—Equipment or physical constants identified by NIST to serve as a basic measurement reference throughout the United States.

b. Air Force Measurement Standards—Equipment certified by NIST or AFMETCAL – approved sources, and used by the AFPSL as a basic measurement reference for the US Air Force.

c. Air Force Base Measurement Standards—Equipment certified by the AFPSL or AFMETCAL-approved sources for use by an Air Force PMEL as a measurement reference.

d. Calibration Systems-A collection of calibration standards and ancillary equipment that are uniquely configured to support a specific workload or multiple measurement parameters.

10 AFI 21-113 12 November

(Calibration Systems have been historically referred to as ‘MetCal’ Systems. MetCal systems may be used in an automated or manual mode and are identified with an AFMETCAL cage code.)

e. Working Standards—PMEL-certified TMDE used to calibrate other TMDE.
