32、e end item. Examination of the end item shall be in accordance with 4.4.2.1 through 4.4.2.3. 4.4.2.1 Yard-by-yard examination. Each roll in the sample shall be examined on the napped side only. When the total yardage in the roll does not exceed 100 yards (91.4m) the entire yardage in the roll shall

33、be examined. When the total yardage in the roll exceeds 100 yards (91.4m), only 100 yards (91.4m) shall be examined. Ail defects as defined in Section 1 of FED-STD-4, which are clearly noticeable at normal inspection distance (3 feet) (0.9m) shall be scored and assigned demerit points as listed in 4

34、.4.2.1.1, except that only the slubs and knots which exceed the limits shown on Sears Fabric Defect Scale (see 6.3), “D“ for slubs, or 3-1/2 as applicable, and “C“ for knots shall be scored.
