16、he time of the completed lut of product is submitted to the Government for acceptance the con- tractor shall supply the following inforina- tion accompanied by a certificate w h i c h attests that the information provided is cor- rect and applicable to the product being submitted : (a) A statement t
17、hat the lot complies with all of the quality assurance provisions specified within this specification. (b) Nufiber of units of product in- spected. (c) Results obtained, by defect code, for all inspections performed. (d) Drawing, specification number and date, together with an identifica- tion and d
18、ate of changes.

21、or shall verify at unscheduled intervals all quality assurance operations performed by the contractor. Verification will be per- formed to the extent necessary to assure compliance with the contractual require- ments. Severity of Government inspection of individual chasacteristics will be directly r
22、elated to the seriousness of the classifica- tion assigned.

A lot shall consist of percussion primers produced by one manufacturer
23、in one unchanged process, in accordance with the same drawing, same drawing revision, same specification, and same specification revision. Drawing, spec- ification, and process changes not affecting safety, perf ormance, interchangeability, or storage as determined by the Government shall not necess
24、itate changing the lot inter- fix number. The examinations and tests listed herein shall be performed on inspec- tion lots submitted in accordance with Standards MIL-STD-105, MILSTD-1235, or MIL-STD-414 as applicable. The cri- teria and procedures for the assignment of lot numbers shall be in accord
25、ance with Standard MILSTD-1168. Each lot shall contain- (a) Metal parts of one lot interfix num- ber from one manufacturer. (b) Black powder from not more than one lot from one manufacturer. (c) Primer, percussion M61 (herein after referred to as primer ele- ment) of one lot interfix number from one
26、 manufacturer. 4.2.2 Examination. Sampling plans and procedures for the following classifications of defects shall be in accordance with 3 - : . -. .i . .

All other designs of inspec- tion equipment shall be approved by the inspection element of the agency
32、 administer- ing the contract; submission shall be as directed by the contracting officer. Partial submission of inspection equipment designs is permissible and encouraged. However, the Arsenal completion date for design review will be based on the date of the final submission of designs. Picatinny
33、Arsenal design review will be accomplished normally within one month after receipt. 6.4 Check test for possible deterioration of percussion artillery primers. The fol- lowing tests are designed to prevent the loading of artillery primers which have deteriorated into a major ammunition item. The +est
34、 shall be performed on normal con- ditions for more than 2 years or under adverse conditions for any period of time. If the specification for the ammunition item into which the artillery primers are loaded does not require that the check test be performed, the conkracting officer should insert a pro

Any head assem- bly which fails to comply with the appli- cable requirement shall be classed defective. The test
36、 shall be performed as specified in 4.3.1.1, except that the flash tube and the head assembly shall. be separated in a man- ner that will not damage the head assembly to the extent that the validity of the test results would be questionable. All head assemblies so tested shall be scrapped. . . ;$-T.

The moisture content of the powder shall be determined in accordance with the method specified in Specification MIL-P-223. If the moisture content of any of the powder tested exceeds 0.7 per- cent, the lot of p
42、rimers shall be rejected. Since black powder is hygroscopic, it is advisable to place the powder inl a dry, airtight container immediately u p o n removal, and to run the determination as soon as possible thereafter. 6.5 Cost of check tests. The contracting officer will arrange for the contractor to
43、 be reimbursed for the expense incurred in the performance of the check test.

In the event that a functioning test fix
45、ture is not available, ten sample primers shall be shipped to a Government proving ground and fired as part of a complete round for which it is standard at service pressure, from a weapon for which the round is standard. If any sample primer fails to comply with the applicable requirement, the lot s
46、hall be rejected. 6.7 Functioning test reports.
