QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for
19、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 requirements specified herein, unless disapproved by the Governme

The inspection set forth in this specification shall- become a part of the contractors overall inspection system or quality program. The
22、 absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of assuring that al1 products or supplies submitted to the Government for acceptance comply with al.1 requirements of the contract. Sampling in quality conformance does not authorize s
23、ubmission of known defective material, either indicated or actual, nor does j-t commit the Government to acceptance of defective material. 4.2 Classification of inspections.

The contrator shall submit a first article sample as designated by the Contracting Officer for evaluation in accordance with provisions of 4.3.2. The first article sample shall be ten (10) pounds of ferric acetylacetonate.
25、 The sample shall be obtained from the first production lot which has been produced by the contractor using the same production processes, procedures and equipment as will be used in fulfilling the contract.

PRECAUTION: This specification covers sampling and testing of toxic and hazardous materials. Accordingly, it is emphasized that all appli
32、cable safety rules, regulations and procedures must be followed in handling and processing the triphenyl bismuth. 4.4.3.1 Sampling. Approximately 500 grams of the composition shall be selected from each batch to be sampled using ASTM Method E300-73 for solids. Samples shall be selected for inspectio
