33、therwise specified, all inspections shall be performed in accordancewith the test conditions specified in 4.6 and 4.7.4.3 First article inspection. First article inspection shall be performed after award of contract and priorto production at a location acceptable to the Government. First article ins
34、pection shall be performed onsample units which have been produced with equipment and procedures normally used in production.First article approval is valid only on the contract under which it is granted, unless extended by theGovernment to other contracts.4.3.1 Sample size. Unless otherwise specifi
35、ed (see 6.2), 25 header glass assemblies, 25 loaded ignitionelement assemblies and 94 cartridge assemblies shall be submitted for first article inspection.4.3.2 Inspection routine.4.3.2.1 Header glass seal assembly.

The number in parentheses denotes number ofcartridges. Temperature conditioning a
38、t the extremes shall be no less than 6 hours and no more than 24hours. Firings shall be conducted in the variable volume test fixture. No cartridge shall produce resultsoutside the limits of 3.5.1 through 3.5.4 and no cartridge shall fail to meet the limits of 3.5.5.4.3.3 Failures. The failure of an
39、y cartridge to meet the requirements as stated above shall causerejection of the first article sample. If more than 5 cartridges fail the leak test specified in 4.6.3.3 the firstarticle sample shall be rejected.4.4 Classification of characteristics. The characteristics verified by the tests and exam
40、inations hereinare classified as Critical, Major or Minor in accordance with DOD-STD-2101.
