33、s 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 of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform
34、 any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1,l Responsibility for compliance. All items shall meet all requirements of section 3 and 5. The inspection set forth in this spec
35、ification shall become a part of the contractors 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 supplies submitted to the Government for acceptance c
36、omply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Gover
37、nment to acceptdefective material. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-Li3375E 3 W 7777706 OLiCOb75 3 V 3 rn MIL-C-43375E( GL) 4.1.2 Certificates of compliance.

When the total yardage in the roll does not exceed 100 yards, the entire yardage in the roll shall be examined. when the total yardage in the roll exceeds 100 yards, only 100 yards shall be examined. All defects, as defined in section III of FED-STD-4, which are cle

The lot shall be unacceptable if the points per 100 square yards of two or more individual rolls exceeds 53 points. sample of 20 rolls
44、 shall be examined only for individual roll quality. The lot shall be unacceptable if one or more rolls in the second sample exceeds 53 points per.lOO square yards. Point computation for lot quality and individual roll quality shall be as follows: Total points scored in sample X 3600 = Points per 10
