as follows:

4.3 Conformance inspection. Sampling for inspection shall be as specified in the contract or
purchase order.

4.3.1.1 Yard by yard examination. During the yard by yard examination, each roll in the
sample shall be examined on one side only for the defects listed below. However, the side of
the cloth examined shall be alternated on every other roll. The same yardage shall be given a
through-lighting inspection for pinholes and for thin areas in accordance with MIL-STD-
1487. All defects found shall be counted regardless of their proximity to each other, except
where two or more defects represent a single local condition of the cloth, in which case only
the more serious defect shall be counted. The sample unit shall be one linear yard. An
approximate equal number of yards shall be examined from each roll in the sample.
