QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the con
28、tract or purchase order, the supplier is responsible for the per- formance of all inspection requirements as specified herein. Except as otherwise specified in the contract or order, the supplier may use his own or any other facilities suitable for the performance of the inspection requirements spec
29、ified herein, unless disapproved by the Government. “he Government reserves the right to perform any of the inspections set forth inthe specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.2 E. Unless otherwise specified (see

Sample drillings shall be taken from three sample spikes selected at random from each 10 tan lot of spikes offered for acceptance. 4.3.3 Sampling for tension test. When the manufacturer requests to conduct a tension test instead of chemical analysis, one sa
33、mple spike shall be selected from each 10 ton lot or fraction thereof for the tension test. 4.3.4 Sampling for bend test. One sample spike shall be selected from each 5 tons or fraction thereof in a lot for the stem (body) bend test and another sample spike for the head bend test. 4.4 Examination. S
