When specified in the acquisition document (see 6.2), a sample shall be subjected to first article in
23、spection (see 6.3) in accordance with 4.3. 3.6 Workmanship. The manufacturer shall implement procedures and controls to assure that the process and the product are not compromised by foreign materials and contaminants or any other conditions which may degrade the composition. Determination of foreig
24、n materials shall be in accordance with 4.5.12. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of required inspections, examinations and tests as specified herein. Except
25、 as otherwise specified in the contract or order, the supplier may use his own or any other facilities suitable for the performance of the inspections, examination and tests specified herein, unless disapproved by the Government. In addition, the Government reserves the right to perform any of the i
26、nspections set forth in the specification where such inspections are deemed necessary to assure supplies and services Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-L-16355E w/Amendment 1 . 5conform to prescribed requirements. Reference shall be
27、 made to ANSI/ISO/ASQ Q9000-2005 to define terms used herein. 4.1.1 Responsibility for compliance. Basic lead styphnate shall meet all requirements of sections 3 and 5. The inspections set forth in this specification shall become a part of the contractors overall inspection system or quality program
28、. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing op
29、erations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.2 Classification of inspections. The required inspectio
30、ns specified herein are classified as follows: a. First article inspection (see 4.3) b. Quality conformance inspection (see 4.4) 4.3 First article inspection. 4.3.1 Submission. When specified in the contract or purchase order, the contractor shall submit a first article sample consisting of one (1)
31、pound of basic lead styphnate. The first article sample shall be obtained from the first production lot which has been produced by the contractor, using the same production processes, procedures and equipment as will be used in fulfilling the contract. All raw materials used in producing the basic l
32、ead styphnate shall be from the same sources as will be used in regular production. 4.3.2 Inspections to be performed. The first article sample may be subjected by the Government to any or all of the examinations or tests specified herein. 4.3.3 Rejection. If the sample fails to comply with any of t
33、he applicable requirements, the first article quantity shall be rejected. The Government reserves the right to terminate its inspection upon any failure of a sample to comply with any of the stated requirements.

A lot shall consist of one or more batches produced by one manuf
35、acturer, in accordance with the same specification, or same specification revision, under one continuous set of operating conditions. Each batch shall consist of that quantity of basic lead styphnate that has been subjected to the same unit chemical or physical process intended to make the final pro
36、duct homogenous. The criteria and procedure for the assignment of lot numbers shall be in accordance with MIL-STD- 1168. 4.4.2 Examination and tests. 4.4.2.1 Classification of characteristics. Quality conformance examinations and tests are specified in the following classification of characteristics
37、 paragraphs. The contractors quality program or detailed inspection system shall provide assurance of compliance of all characteristics with the applicable specification requirements utilizing as a minimum the conformance criteria specified herein.

PRECAUTION: This specification covers sampling and testing of toxic and hazar
42、dous material. Accordingly, it is emphasized that all applicable safety rules, regulations and procedures must be followed in handling and processing. 4.4.3.1 Sampling. Obtain two random 30 gm samples from each batch of basic lead styphnate being submitted for inclusion in a lot. The samples shall b
43、e obtained from the process vessel prior to packout using procedures described in ASTM-E300 for slurries. 4.4.3.2 Testing for batch acceptance. One sample obtained according to 4.4.3.1 from each batch shall be tested in accordance with applicable test methods of 4.5 for conformance with the requirem
44、ents for color and crystalline form (see 3.1), crystal dimensions (see 3.2), apparent density (see 3.4), acidity, pH (see 3.4), and workmanship (see 3.6). If any sample fails to meet any of these requirements, the batch represented by the sample shall be rejected. Rework of non-conforming batches is
45、 permitted. 4.4.3.3 Testing for lot acceptance. The second samples from the batches not rejected under the provisions of 4.4.3.2 shall be placed in a suitable container of sufficient volume to hold a composite sample from all batches in the lot. The composite sample shall be thoroughly mixed to assu
46、re homogeneity, and two sub-samples of approximately 30 gm each shall be obtained from this composite sample. Both sub-samples shall be tested in accordance with the applicable test methods of 4.5 to determine conformance with the requirements of granulation (see 3.3), material insoluble in ammonium
47、 acetate (see 3.4), material soluble in ether (see 3.4), lead content (see 3.4), nitrogen content (see 3.4), and instantaneous flash point (see 3.4). If either sub-sample fails to meet any of the test requirements, the lot represented by the composite sample shall be rejected. 4.4.4 Inspection equip
48、ment. For the performance of all test and examinations specified in 4.3 and 4.4, the equipment specified should be employed. The contractor shall have this equipment available, utilize it in accordance with the test method, and is responsible to assure that it is properly calibrated.
