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.
