32、ll, spool or tube, of webbing shall be labeled or ticketed for fiber content in accordance with the Rules and Regulations under the Textile Fiber Products Identification Act. 3.8 Workmanship. The finished webbing shall conform to the quality and grade of product established by this specification. Th
33、e occurrence of defects shall not exceed the applicable acceptable quality levels. 3.9 Date of manufacture. When 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 containers i
34、dentifying the specification to which the material is manufactured, the lot number and the date of manufacture. 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 Classificat
35、ion of inspection. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.2) b. Conformance inspection (see 4.3). 4.2 First article inspection. The first article shall be submitted in accordance with 3.1 and shall be inspected as specified in 4.3 t
36、hrough 4.4 for compliance with design, construction, workmanship and dimensional requirements. 4.3 Conformance inspection. Conformance shall include examination of 4.3.1 and the tests in 4.4 through 4.5 as applicable. Sampling for inspection shall be performed as specified in this document, unless o
37、therwise specified in the contract or order. 4.3.1 Component and material inspection. In accordance with 4.1 above, components and materials shall be inspected in accordance with all the requirements of referenced specifications, drawings, and standards unless otherwise excluded, amended, modified,
38、or qualified in this specification or applicable procurement documents. 4.3.2 Certificates of Compliance. When Certificates of Compliance are submitted, the procuring activity reserves the right to inspect items to determine the validity of the certification. 4.3.2 End item examination. Defects foun
39、d during the examination shall be classified in accordance with 4.4.1 through 4.4.3. 4.4 End item examination. 4.4.1 Yard-by-yard examination. The required yardage of each roll, spool or tube, shall be inspected on both sides for the defects listed in TABLE II. All defects found shall be counted reg
40、ardless of their proximity one to another, except where two or more defects represent a single local condition of the webbing, 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 occur
41、s. The lot size shall be expressed in yards. The sample unit shall be one linear yard. Inspection sampling and procedures shall be in accordance with ANSI/ASQ Z1.4. The inspection level shall be III and the Acceptable Quality Limit (AQL), expressed in terms of defects per hundred units, shall be 2.5
42、 for minor defects. In addition, the finding of one or Page 6 of 20 Copyright Protected: Do Not Copy!PIA-T-87130C more critical defects will be cause for rejection of the lot. The number of rolls from which the sample is to be selected shall be in accordance with TABLE III of this specification. The
43、 sample yardage shall be equally selected among the selected rolls. TABLE II Classification of defects.
