Type C weights shall be made from inor- ganic material that, when form
16、ed, shall have a minimum compression strength of 2,500 pounds per square inch and a minimum density of 200 pounds per cubic foot. Blocks shall be resistant to crumbling in handling. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purch
17、ase order, the contractor is responsible for the performance of all inspection requirements 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 require- ments speci
18、fied herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the speci- fication where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance.
19、 All items must meet all require- ments of sections 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 reIieve the contractor of the res
20、ponsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all require- ments 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
21、 acceptance of defective material. 4.2 Sampling. 4.2.1 - Lot. All weights of the same type offered for delivery at the same time shall be considered a lot. 4.2.2 Sampling for examination. A random sample of weights shall be selected from each lot in accordance with table II for the examination speci

Sample weights selected in accordance with 4.2.3 shall be checke
26、d for density to determine conformance to the requirements of this specification. Any sample weight which does not meet the requirements for that sample shall cause rejection of the lot represented by the sample. 4.5 Inspection of packaging.
