4.3.1.3 Shade and appearance examination. During the yard-by-yard examination, each roll
in the sample shall be examined on the face side for shade and appearance. If any roll in the
sample is off shade or shaded side to side, side to center, or end to end, or if any roll does not
have the same appearance as the standard sample, it shall be considered a shade and
appearance defect.
4.3.2 End item testing. The cloth shall be tested for the characteristics listed in Table IV.
The methods of testing specified wherever applicable and as listed in Table III shall be
followed. The sample unit for testing shall be 3 continuous yards full width of the finished
cloth. The lot shall be unacceptable if any sample unit fails to meet any requirement
specified. All test reports shall contain the individual values utilized in expressing the final
results.
