Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements as specified herein. Exc
25、ept 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 any of the inspections
26、 set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. Al1 items must meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a
27、 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 supplies submitted to the Government for acceptance comply with all requireme
28、nts 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 The contractor shall have the toxicological formulations and associated information
29、 available for review by the contracting activity to evaluate the safety of the material for the proposed use. 4.2 Quality conformance inspection. 4.2.1 Sampling for quality conformance. 4.2.1.1 - Lot. For purposes of sampling, a lot shall consist of all material manufactured as one batch and offere
30、d for delivery at one time. 4.2.1.2 Sampling for tests. From each inspection lot, the inspector shall select two containers at random. From each of the two containers, 1-pint samples shall be taken and placed in separate clean, dry, metal or glass containers, sealed and marked. 4.2.1.3 Sampling for
31、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, with an acceptable quality level (AQL) of 2.5 percent defective to verify compliance with this specification regarding fill, closure, marking
32、and other requirements not involving tests.

Each sample filled containers shall be examined for def
33、ects of construction of the container and the closure, for evidence of leakage, and for unsatisfactory markings; each filled container shall also be weighed to determine the amount of contents. Any container in the sample having one or more defects, or under required fill, shall be rejected, and if

If a sample fails to comply in any respect to this specification, the lot which it represents shall be r
36、ejected. Rejected lots may be resubmitted for acceptance tests, provided the manufacturer has removed or reworked all non- conforming products. 4.5 Test procedures. 4.5.1 Preparation of inhibited acid solution. 4.5.1.1 The inhibited acid solution shall be formulated as follows: Hydrochloric acid, 23
