QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible

33、 for the performance of all inspection requirements as specified herein. fied 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 r

34、eserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. Except as otherwise speci- 4.1.1 Responsibility for compliance. All items must meet all requirements of s

35、ections 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 relieve the contractor of the responsibility of assuring that all products or

36、 supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Inspe

37、ction system. The contractor shall provide and maintain an inspection system in accordance with the data ordering documents included in the contract or order (see 6.2.2). 4.2 Quality conformance inspection. 4.2.1 - Lot. For purposes of sampling, a lot shall consist of all solutions or chemicals from

38、 one batch of a single class. 4.2.2 Sampling for examination of filled containers. A random sample of filled containers shall be selected from each lot in accordance with MIL-STD-105 at inspection level I, and acceptable quality level (AQL) of 2.5 percent defec- tive to verify compliance with all re

39、quirements of this specification regarding fill, closure, marking, and other requirements not involving tests. 4.2.3 Sampling for quality conformance tests. Unless a different labora- tory is specified (see 6.2.1), 60 bottles shall be selected from each lot of material and forwarded to the David W.

40、Taylor Naval Ship Research and Develop- ment Center, Annapolis Laboratory, Annapolis, MD 21402 for the tests specified in 4.4 and 4.5.
