3.12.2 Maintenance provisions. Equipment shall be as specified in a through f to facilitate maintenance:
a. Accessibility for maintenance. The equipment shall be designed to ensure that any necessary maintenance access can be accomplished utilizing ordinary tools. The equipment shall be constructed so that no damage to any component shall occur and no permanent distortion to any structural member shall be caused during maintenance and calibration.
b. Maintenance and calibration aids. Special adapters, special tools, circuit board extenders, and patch or interface cables required for maintenance or calibration shall be provided. They shall be identified as a set with a unique part number. Stowage shall be in a reusable pouch or container.
c. Calibration/alignment. The VLPC shall be provided with all necessary instructions, and firmware if needed, to calibrate and align the equipment so that the equipment meets its performance specifications after repair or due to the equipment failing calibration.
d. Calibration and alignment. The VLPC shall be able to be calibrated and aligned utilizing the digital interface and an external pressure reference standard.
e. Navy calibration standards. The VLPC shall be able to utilize existing industry calibration standards that meet all necessary minimum performance requirements to satisfy an adequate traceable calibration.
f. Alignment data. If the equipment has alignment data stored in memory (e.g.: EEPROM, data files, DACs, etc.) that is necessary for the equipment to meet its performance specification, and modification of this alignment data is necessary after repair or a calibration failure, the equipment shall be designed and information provided so that the alignment can be performed by the Navy.
3.13 Firmware updates. The equipment shall be designed to allow for the Navy to update the equipment firmware. For the length of the contract and any subsequent warranty period beyond the length of the contract, the manufacturer shall provide to the Navy notification of any firmware updates, instructions on how to perform the update, and free access via appropriate media transfer method supported by the Navy (e.g. ROM disc, Website, email) to firmware updates that fix bugs relating to any of the performance requirements cited in this specification. For the same time period, the manufacturer shall provide to the Navy notification of any improvements relating to any performance requirements cited in this specification. The firmware update process shall use any common interface path supported by the equipment (e.g. the USB DVD-ROM drive available with the device).
3.14 Calibration. For the purpose of this CSS, calibration refers to the process of comparing a test instrument with a calibration standard to determine the indicated error at specified test points. Alignment refers to the process of characterizing and adjusting a test instrument to cause it to indicate within its specified accuracy limits.
3.15 Calibration certificate. The equipment provided under this CSS shall have a current calibration certificate, with a calibration data sheet, traceable to the National Institute of Standards and Technology (NIST).
3.16 Calibration interval. The minimum interval between calibrations shall be 12 months. At the end of this interval, a minimum of 85 percent of the units shall remain in tolerance.
3.17 Reliability. The design of the equipment shall be such that under normal use and operation the equipment does not fail within one year or 1500 hours of operation, whichever comes first, with a statistical certainty of 95%. The manufacturer shall provide a summary of maintenance or warranty records to establish the validity of the statistical assertion. If records of the actual equipment model offered are not available, records from a similar model may be substituted. The manufacturer shall be able to reasonably establish the claim that the offered equipment shall provide reliability similar to the model used to provide substitute records.
3.18 Warranty. All units shall be provided with the manufacturer's standard commercial warranty. The minimum acceptable duration for such a warranty is one (1) year.
3.19 Warranty label. The equipment shall have a warranty label that reflects the start and end dates of the warranty.
3.20 Operation and Maintenance Manual. Two copies (1 hard copy and 1 CD/DVD media) of an operation and maintenance manual shall be provided with each unit. The manual and text contained within shall be of high quality and provide for maximum clarity and understanding, using illustrations and/or drawings, where appropriate, to aid the operator. Duplications of existing user documentation from the various VLPC component suppliers are suitable if they are of adequate detail and quality. The technical manuals shall be provided in both printed and electronic format. The hard copy manual shall be bound in a binder of durable quality that ensures longevity for the duration of the VPLC. The electronic copy shall be in a Portable Document Format (PDF) and shall conform to ISO 32000-1:2008.
3.20.1 Copyright release. A statement of copyright release for reproduction of technical manuals for government use shall be printed in the first two pages of each technical manual. If an existing manual is provided, the statement of copyright release for reproduction shall be permanently affixed/marked in the manual. A statement of copyright release for reproduction of the technical manual CD for government, including posting on a government restricted website, use shall be printed on each CD.
3.20.2 Style and format, technical manuals. All text shall be legible. A cover page shall include, equipment name and model number. A table of contents shall be provided.
3.20.3 Content, technical manual. The manual shall contain the existing individual VLPC component user manuals, applicable individual instrument calibration procedures, drawings, pictures, data sheets, lists and documentation organized in a clear, concise and logical manner, with appropriate notes, warnings and cautions where applicable to prevent injury to personnel and damage to equipment. An overall VLPC parts list shall also be included in the manual with part number, kit and available ordering information such that the VLPC replacement parts list is easily accessible.
3.20.4 Maintenance. Existing user documentation which may include applicable instructions for cleaning, inspection, disassembly and reassembly, adjustment and any other preventative or corrective maintenance is acceptable.
3.20.5 Battery information. If batteries are used in the equipment, instructions shall be included that describe the procedure for battery replacement – part number and description. Proper disposal procedures shall be contained in the manual.
3.20.6 Illustrated Parts List. As listed above, an overall VLPC parts list with part numbers, kit information ordering detail shall be incorporated into the manual.
3.21 Workmanship The manufacture, assembly and packaging of the items covered by this CSS shall conform to the requirements of this CSS. All items will remain securely held in place during normal transit. Adequate protection will be afforded for the equipment on all sides to avoid transient damage.
4.0 Equipment Sample Requirements. The equipment shall be given a thorough visual examination and performance test to determine that all materials, workmanship and performance characteristics comply with the specified requirements. It will also serve to verify that any substitution of parts is acceptable and that they meet the requirements of this CSS specification. Two samples of the first production units shall be required for this inspection. Non-compliance will result in return for rework. MIL PRF 28800 paragraph 4.5.3.1 (a) applies.
