The required yardage of each roll in the sample shall be examined on the face side and visual defects as defined in MIL-STD-1491 shall be classified as listed. All defects found shall be counted regardless of their proxim
35、ity 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. A continuous defect shall be counted as one defect for each wale-wise (lengthwise) yard (0.91m) r fraction thereof in which it occurs. The
36、 sample unit for this examination shall be one linear yard (0.9lm). The acceptable quality levels for this examination shall be 2.5 major defects and 6.5 total defects (major and minor combined) per 100 units (yards) (91.4m). The sample size shall be based upon inspection level II of MIL-STD-105. Th
