31、hen required by the procurement document, the textile manufacturer shall properly identify the age of the textile materials by placing a tag on the finished goods, or label on the container, identifying the specification to which the material is manufactured, the lot number and date of manufacture.
32、The date of manufacture is defined as the date (month and year) of the last manufacturing process that affects the physical characteristics of the material. 4. VERIFICATION 4.1 Classification of inspection. The inspection requirements specified herein are classified as follows: a. First article insp
33、ection (see 4.2) b. Quality conformance inspection (see 4.3). 4.2 First article inspection. The first article submitted in accordance with 3.1 shall be inspected as specified in 4.3 and 4.7 for compliance with design, construction, workmanship, and dimensional requirements. 4.3 Conformance inspectio
34、n. Conformance inspection shall include the tests of 4.7 through 4.8.2 as applicable. Unless otherwise specified, sampling for inspection shall be performed as specified in this document or in the contract or order (see 6.2). 4.4 Responsibility for inspection. Unless otherwise specified in the contr
35、act or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance o
36、f 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 specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.
37、5 Responsibility for compliance. All items shall meet all requirements of Sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not re
38、lieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract.

Where Certificates of Compliance are submitted in accordance with TABLE IV, they shall contain verifiable actual test and inspection data. The Government
40、reserves the right to inspect such items to determine the validity of the certification. 4.7 End item inspection. 4.7.1 Yard-by-yard examination. The tape shall be examined on both sides for the defects listed in TABLE III. All defects found shall be counted regardless of their proximity to each oth
41、er, except where two or more defects represent a single local condition, in which case only the more serious defect shall be counted. A continuous defect shall be counted as one defect for each warp-wise yard or fraction thereof in which it occurs. The lot size shall be expressed in yards. The sampl
42、e unit shall be one yard. The inspection level shall be III and the Acceptable Quality Limit (AQL), expressed in terms of defects per hundred units, shall be 2.5 for minor defects. In addition, the finding of one or more major defect(s) shall be cause for rejection of the lot. The number of rolls fr
43、om which the sample yardage is to be selected shall be in accordance with TABLE II. The sample yardage shall be apportioned equally among the selected rolls. TABLE II Sample size.
