Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all in
26、spection 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 of the inspection requirements specified herein, unless disapproved by the Governme
27、nt. 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 . 4.2 Responsibility for compliance. All items shall meet all requirements of section
28、s 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 this specification shall not relieve the contractor of the responsibility of ensuring that all products or supp
29、lies submitted to the Government for acceptance comply 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
30、indicated or actual, nor does it commit the Government to accept defective material. 4.3 Inspection equipment. Inspection equipment required to perform the examinations and tests prescribed herein is described in the .ttInspection Method Reference“ column in the tables starting with 4.4.2 4.4 Classi
31、fication of inspections. The following types of inspections shall be conducted on this item: a. First article inspection b.

42、2 Alternative inspection provisions. Alternative inspection procedures, methods or equipment, such as statistical process control, tool control, other types of sampling procedures, etc., may be used by the contractor when they provide, as a minimum, the level of quality assurance required by the pro
43、visions specified herein. Prior to applying such alternative procedures, methods, or equipment, the contractor shall describe them in a written proposal submitted to the procuring contracting officer for evaluation and approval by the Government (see 6.4). When required, the contractor shall demonst
44、rate that the effectiveness of the proposed alternative(s) is equal to or better than the specified quality assurance pro-!isions herein.
