4.3.2.1 Yard-by- yard examination. Each roll in the sample shall be examined on the face
side only. When the total yardage in the roll does not exceed 100 yards, the entire yardage in the
roll shall be examined. When the total yardage in the roll exceeds 100 yards, only 100 yards
shall be examined. All defects are defined in Section 1 of FED-STD-4, which are clearly
noticeable at normal inspection distance (3 feet), shall be scored and assigned demerit points as
listed in 4.3.2 except that only those slubs and knots which exceed the limits shown on Sears

(increments of 1 yard on the measuring device of the inspection machine) from any one roll
within the sample shall be penalized more than four points. The sample size shall be 20 rolls
selected from 20 containers. The lot shall be unacceptable if the points per square yards of the
total yardage examined exceeds 20.0 points. The lot shall be unacceptable if the points per
square yards of two or more individual rolls exceeds 30.0 points. If one roll exceeds 30.0 points
per square yards, a second sample of 20 rolls shall be examined only for individual roll quality.
The lot shall be unacceptable if one or more rolls in the second sample exceeds the point level.
Point computation for lot quality and individual roll quality shall be as follows:
Total points scored in sample x 3600
=
Points per 100
Contracted width of cloth (inches) x Total yards inspected
