4.1 Classification of inspection. The inspection requirements specified herein are classified as
follows:
a. First article inspection (see 4.3).
b. Conformance inspection (see 4.4).
4.2 Lot. A lot shall consist of all plate of the same alloy; same source of molten metal representing
the ingots poured, and ordered thickness which has been processed together by the same mill

production has commenced, samples of specified material shall be made available to the contracting
officer or his authorized representative for approval in accordance with 4.3.1. The approval of the
first article samples authorizes the commencement of production but does not relieve the supplier of
responsibility for compliance with all applicable provisions of this specification. The first article
samples shall be produced using the mill production practice proposed for use in production.
4.3.1 First article inspection. First article inspection except as otherwise indicated in this
specification, shall utilize the same requirements and test methods as the conformance inspection or
production acceptance inspection shown in 4.4.
4.4 Conformance inspection. Conformance inspection or production acceptance inspection shall
include the examination of 4.6 and the tests of 4.7.
