36、 the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this document where such inspections are deemed necessary to assure supplies and services conform to prescribed req
37、uirements. 4.1.1 Responsibility for compliance. All items must meet all requirements of Sections 3 and 5.

40、ce. Where certificates of compliance are submitted, the Government reserves the right to check test such items to determine the validity of the certification. 4.2 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4
41、.3). b. Quality conformance inspection (see 4.4). 4.3 First article inspection. When a first article is required (see 6.2), it shall be examined for the appearance and length defects listed in Table III and tested for the characteristics specified in Table IV. The presence of any defect or failure t

If the total number of defects in the sample rolls exceeds the applicable acceptance number specified in Table II; or if
45、the total of the actual lengths of the sample rolls is less than the total of the lengths marked on the roll tickets, the lot shall be rejected: Total length of roll less than 180 yards or more than 220 yards. Total length of roll is 2 or more yards less than that marked Roll contains more than four

The required yardage of each roll shall be examined on one side only; however, the side shall be alternated so that alternate rolls are examined on the face and back, re
48、spectively. The defects found shall be counted regardless of their proximity 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 warpw
49、ise yard or fraction thereof in which it occurs. The lot size shall be expressed in units of yards. The sample unit shall be 1 linear yard. The inspection level shall be III, and the Acceptance Quality Level (AQL), expressed in terms of defects per hundred units, shall be 1.5 for major defects and 2.5 for total (major and minor combined) defects. The number of rolls from which the sample yardage is to be selected shall be as specified in Table II. The sample yardage shall be apportioned equally among the selected rolls. TABLE II.
