Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of al
30、l 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 performance of the inspection requirements specified herein, unless disapproved by the Governme
31、nt. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. * 4.1.1 Responsibility for compliance. All items must meet all requirements of sectio
32、ns 3 and 5, The inspection set forth in this mecification shall become a part of the contrators overall inspection System or quality program. The absence of any inspection requirements in the specification- shall not relieve the contractor of the responsibility of ensuring that all products or suppl
33、ies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indi
34、cated or actual, nor does it commit the government to acceptance of defective material. 4.1.2 Certificate of Compliance. 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 in
35、spection. The inspection requirements specified herein are classified as follows: 1. First.article inspection (see 4.3). 2. Quality conformance inspection (see 4.4). * 4.3 First article inspection. When required, the Eirst article submitted in accordance with 3.2, shall be inspected as specified in
36、4.4,2 for compliance with design, construction, workmanship, appearance and dimensiohal requirements and tested in accordance with paragraph 4.5 and Table II, 4.4 Quality conformance inspection.

In accordance with 4.1 above, components and materials shall be tested in accordance with all the requirements of referenced specifications, drawings, and standard
38、s unless otherwise excluded, amended, modified, or qualified in this specification or applicable procurement documents. In addition, a certificate of compliance shall be submitted for the material requirements of 3.3.1 and 3.3.2. 4.4.2 Examination of the end item. Examination of the end item shall b
39、e in accordance with 4.4.2.1 through 4.4.2.5. 4.4.2.1 Yard-by-yard examination. Each roll in the sample shall be examined on face side only. When the total yardage in the roll does not exceed 100 yards (91.4m), the entire yardage in the roll shall be examined. When the total yardage in the roll exce
40、eds 100 yards (91.4111) only 100 yards (91.4111) shall be examined. All defects as defined in Section III of FED-STD-4, which are clearly noticeable at normal inspection distance (3 feet) (0.91m) shall be scored and assigned demerit points as listed in 4.4.2.1.1, except that only those knots which e
41、xceed the limits shown on Sears Fabric. Defect Scale (see 6.4), “C“ knots shall be scored. No linear yard (increments of 1 yard (0.91m) on the measuring device of the inspection machine) from any one roll within the sample shall be penalized more than 4 points. The sample size shall be 20 rolls sele
42、cted from 20 containprs. The lot shall be unacceptable if the points per 100 square yards (83.6111 ), of the total yardage examined exceeds 25 pointsi The lot shall be unacceptable if the point per 100 square yards (83.6m ) of two or more individual rolls exceeds 238 points. If one roll exceeds the
43、point level per 100 square yards (83.6111 ) a second sample of 20 rolls shall be examined only for individual roll quality examination. The lot shall be unacceptable if one or mo;e rolls in the second sample exceeds 38 points per 100 square yards (83.6111 ). Point computation for lot quality and ind
44、ividual roll quality shall be as follows: Total points scored in sample x 3600 = Points/100 Contracted width of cloth (inches) x total yards inspected square-yds * 4.4.2.1.1 Demerit points. Demerit points shall be assigned as follows: For defects 3 inches (7.6cm) or less 5n any direction one point F
45、or defects exceeding 3 inches (7.6cm), but not exceeding 6 inches (15.2cm) in any direction - two points For defects exceeding 6 inches (15.2cm), but not exceeding 9 inches (22.9cm) in any direction - three points For defects exceeding 9 inches (22.9cm) in any direction - four points The following d
46、efects, when present, shall be scored 4 points for each yard (0.91m) in which they occur: Baggy, ridgy or wavy cloth Width less than specified Characteristics of finish, hand and shade not equal to the standard sample Non uniformity of shade (mottled, streaky or cloudy) Holes, cuts, tears, open plac

During the yard-by-yard examination, each roll in the sample shall be examined for length. Any length found to be less than the minimum specified o
48、r more than 2 yards (1.82111) less than the length marked on ticket shall be considered a defect with respect to length. The lot shall be unacceptable if two or more rolls in the sample are defective with respect to length. 4.4.2.2.2 Total yardage in sample. The lot shall be unacceptable if the tota
49、l of the actual lengths of rolls in the sample is less than the total of the lengths marked on the tickets. The rolls examined shall be those selected for the examination of individual rolls. 4.4.2.3 Examination for shade variation. During the yard-by-yard examination, each roll in the sample shall be examined for shade variation. Any role in the sample exhibiting uneven shade, shade variation side to side, side to center, or end to end, shall be cause for rejection of the entire lot represented by the sample. 4.4.2.4 Examination for shade match and finish, individual rolls.
