MIL-HDBK-1839A APPENDIX A
capable of a minimum 4 to 1 TUR; identifies SE, calibration standards, and calibration procedure requirements; and recommends the calibration laboratory level where calibrations should be performed.
3. Where do I find calibration standards?
Response: Calibration standards are unique to each service and should be selected from the contracting service's document of standards. Specifically these are: Air Force TO 33K-1-101; Army Drawing 7917000/1 and 8205511; or Navy NAVAIR 17-35-NCE-1.
4. What does a CMRS look like?
Response: An example of a CMRS is provided in appendix B of this handbook. Additionally, there are illustrations in DID DI-QCIC-80278.
5. What is full traceability?
Response: Full traceability applies to measurements/calibrations made from the weapons system or subsystem through an unbroken chain of comparisons to national or international reference standards. The International Vocabulary of Basic and General Terms in Metrology (VIM) defines traceability as "Traceability is the property of the result of a measurement or the value of a standard
whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties."
6. When does the requirement for CMRS category IV, and higher, go into effect?
Response: When category III lists a calibration standard that is not a DoD approved standard
(See 5.4.2a).
7. What is the relationship of the CMRS to the rest of the LSA?
Response: The CMRS is an integral part of the LSA process for the development of a new weapons system. The MIL-STD-1388 LSA process had the CMRS as a part of the LSAR. With the advent of the Logistics Management Information (LMI) process for new development systems, the process allows for incorporation of the CMRS into the LMI. If the Program Office opts to not develop a CMRS within the LMI process, the Program Office can use MIL-STD-1839 and develop a stand alone CMRS. In any case, the CMRS is a vital element in the LSA process which,
if done properly, will likely influence design and help to optimize the support of the weapons system, minimize the Life Cycle Costs associated with calibration of the new system, and optimally enhance the reliability of the weapons system.
8. What are the roles and responsibilities of those involved in CMRS development.
