VERIFICATION 4.1 Classification of inspections. The inspection requirements specified herein are classified as follows: Provided by IH

36、SNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-18714F (OS) 6 a. First article inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.2 Test and examination methods. Primers shall be selected at random for each test or examination. Identifica

37、tion of each primers complete test and examination results shall be secured for additional examination until otherwise directed by the contracting activity (see 6.6). 4.3 First article inspection. The first article shall be a homogeneous (6.7.7) sample of 130 assembled primers and five-each of every

38、 component part and sub-assembly (less explosive components) fabricated, packaged, and packed in accordance with the requirements of this specification and the contract or purchase order using the methods and procedures to be used for production. The first article shall be submitted to the governmen

39、t facility designated in the contract or order for test and examination in accordance with the first article inspection plan of Table I (see 6.2 and 6.3). Prior to delivery, a first article shall be inspected and tested for all requirements specified herein. 4.3.1 Five-each inspection. 5 units of ev

40、ery part and non-explosive sub-assembly shall be selected from a population that is representative of parts to be used for standard primer production. Each of these parts and sub-assemblies shall be inspected for compliance with the requirements of their respective designs (drawings and specificatio

41、ns). These shall be the same inspections that are performed during quality conformance for parts and sub-components (see 4.4.3 and Tables II through XXVIII). 4.3.2 First article rejection. Failure of the first article sample to meet any of the requirements shall be cause for failing first article. 4

44、ing 2434753). The following clarifications apply: a. A change in the bridge-wire manufacturers lot shall lead to a change in the ignition element lot; b. For a single lot of ignition elements, the ignition charge (drawing 2434757) may be manufactured in small batches if the batches come from the sam

45、e manufacturer using the same lots of ingredients and are manufactured with no break in production for longer than 20 working days. 4.4.2 Primer inspection. Unless otherwise specified in the contract or purchase order (see 6.2), 105 samples shall be selected at random from each production lot for te

46、st and examination at the government facility designated in the contract or order in accordance with the quality conformance inspection plan of Table I.
