4. QUALITY ASSURANCE PROVISIONS
4.1 Classification of inspections. The inspection requirements specified herein are classified 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 Inspections.
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 procedures 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 tests 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 service 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 contractor's risk. Failure of any initiator to comply with the requirements of section 3 shall be
cause for 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 through 3.3 shall be rejected and removed from the lot.
