1. First article inspection (see 4.2)
2. Quality conformance inspection (see 4.3)
4.2 First article inspection. The first article, submitted in accordance with 3.1, shall be inspected for
compliance with design, configuration, workmanship and dimensional requirements. The presence of
excessive defects, as defined by contract, (see 4.4.9) or failure to pass any test shall be cause for
rejection of the first article.
4.3 Quality conformance inspection. Sampling for inspection shall be performed in accordance with
ANZI/ASQC Z1.4, as defined by contract, except where otherwise indicated.
4.4 Component and end item inspection. In accordance with 4.1, components and end items shall be
tested in accordance with all the requirements of referenced documents unless otherwise excluded,
amended, modified, or qualified in this document or applicable procurement documents. The
government reserves the right to inspect all components and end items to determine conformance to
requirements.
4.4.1 Bond strength test. The interlining shall meet the requirements stated in 3.3.3 when tested
according to AATCC TM 136, paragraph 11.
4.4.2 Breaking strength and elongation test. The thread and gimp shall meet the requirements stated in
3.3.4 and 3.3.4.1 when tested according to ASTM-D-2256.
4.4.3 Colorfastness test. The thread and gimp shall meet the requirements stated in 3.3.4.2 when
tested according to AATCC TM 61, Test 3A (3 cycles).
4.4.4 Chalking test. The buttons shall meet the requirements stated in 3.3.7 when tested for chalking
by immersion in a boiling solution of 0.8 percent by weight sulfuric acid for 10 minutes, immediately
thereafter dried and examined by holding the button at arm's length under a strong white light.
4.4.5 Compressive strength test. The buttons shall meet the requirements stated in 3.3.7 when tested
for compressive strength using an apparatus which permits gradual application of the load either by a
manual or automatic hydraulic mechanism. Buttons shall be placed face down one at a time between
flat blocks of steel, and tested to failure. Failure is defined as the first sign of a crack in the button
visible to the naked eye (a visible crack in the button will usually be found at the first audible sound of
cracking).
4.4.6 Button pull test. The buttons attached to the coat shall meet the requirements stated in 3.3.7
when tested according to ASTM D-5034, except slide button on top of 1 inch wide grips separated at
