The inspection requirements specified herein are c
33、lassified as follows: a. First article inspection (see 4.2.1) b. Production inspection (see 4.2.2) c. Lot acceptance inspection (see 4.2.3) 4.2.1 First article inspection. Before entering into quantity production, an acceptable first article sample of 38 initiators shall be prepared using the same p
34、rocedures and methods proposed for the production lot. A first article sample acceptable for functional and environmental testing shall be defined as a sample which has met the applicable requirements of 3.2 through 3.3 of this specification. Thirty-six of these initiators shall be expended in the t
35、ests listed in table I and two shall be retained for investigative purposes. The contractor shall deliver the initiators to the activity designated by the contracting agency for tests. Any damage inflicted by the environmental treatments, which would adversely affect the performance of the item in s
36、ervice application shall cause rejection of the first article sample. Any further production prior to notification by the contracting agency of first article sample acceptability shall be at the contractors risk. Failure of any initiator to comply with the requirements of section 3 shall be cause fo
37、r rejection of the first article represented. 4.2.2 Production inspection. All production delay cartridge assemblies and initiators manufactured under contract shall be inspected and screened to requirements specified in 3.2 through 3.3. Any unit failing to meet the requirements listed in 3.2 throug
38、h 3.3 shall be rejected and removed from the lot. 4.2.3 Lot acceptance inspection. Lot acceptance inspection shall consist of the examinations and tests specified in table II.
