29、3 Inspection conditions. Unless otherwise specified, all inspections shall be performed in accordance with the test conditions specified in FED-STD-191. 4.4 First article inspection. When required (see 6.3), the first article sample submitted in accordance with 3.2 shall be visually inspected for ap

30、pearance and color. The sample shall be tested in accor- dance with the methods specified in 4.6. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-4.5 Quality conformance inspection.

Examination of the end item shall be in accordance with 4.5.1.1 through 4.5.1.4. 4.5.1.1 Yard-by-yard examination. The required yardage of each roll shall be examined on the face side and visual defects as define

32、d herein shall be classified as listed in Table II. All defects found shall be counted regardless of their proximity one toanother, 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

33、 be counted as one defect for each lengthwise yard or fraction thereof in which it occurs. The sample unit for this examination shall be one linear yard (0.91m). The sample size shall be in accordance with Inspection Level II of MIL-STD-105. The Acceptable Quality Level (AQL) shall be 2.5 major defe

34、cts and 6.5 total defects per 100 units (yards) (gim). The lot size shall be expressed in units of one linear yard (0.91m) each.
