QUALITY ASSURANC
26、E PROVISIONS 4.1 ResDonsibiitv for insDection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order,
27、 the contractor may use his or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Gov- ernment reserves the right to perform any of the inspections set forth in the specifications where such inspections are dee
28、med necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 ResDonsibilitv for comDliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality
29、 program. absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies sub- mitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufactur
30、ing 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 Government to accept defective material. The 4.1.2 Toxicological Droduct formulations. The c
31、ontractor shall have the toxicological product formulations and associated information available for review by the contracting activity to evaluate the safety of the material for the proposed use. O 4.2 Classification of inspection. The inspection requirements specified herein are classified as foll
32、ows: (a) First article inspection (see 4.3). (b) Quality conformance inspection (see 4.4). 4.3 First article insoection. First article inspection shall be performed on two samples of the formulation being tested and shall consist of the exami- nations and tests specified in 4.6 and 4.7 for type I an
33、d type II formulations, respectively (see 6.4). to any applicable requirements, the contractor shall investigate and correct the root cause of the discrepancy, revise associated process instructions, and retest samples to determine the effectiveness of corrective action. In the event that a first ar
34、ticle sample does not conform 4.4 Oualitv conformance insDection. Quality conformance inspection shall be performed on every lot submitted to the Government, and shall consist of the examination specified in 4.5 and the examinations and tests specified in 4.6 and 4.7 for type I and type II formulati
35、ons, respectively (see 6.3). 4.4.1 m. For the purpose of quality conformance inspection sampling, a lot shall consist of lithium bromide prepared in one continuous, homogenous batch of raw materials, without any addition or change in composition or processing procedure. The introduction of any ingre
36、dient or process change shall constitute a new lot.
