Any pinhole, leak (see 4.4.1), any tear, cut, or sharp crease. Excessive wrin- kles. Bags sticking together to the extent that opening causes
20、tearing or injury to inner surface. Width, length or thickness not as specified. Width or length tolerance not as specified. Marking not as specified. Identification sheet missing. 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the con- tractor is re
21、sponsible 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 requirements specified herein, unless disapproved b

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 mate
25、rial. 4.2 Quality conformance inspection. The material shall be subjected to all the following inspections and tests for acceptance. When specfied in the contract (see 6.2), the contractor shall prepare a report giving the results obtained for all inspections and tests performed and a certified stat
26、ement that the lot meets all the requirements of this specification (see 6.2.2). 4.3 Sampling for lot acceptance. 4.3.1 Lot.

Two specimens from each seam or seal comprising the sample bag shall be tested in accordance with ASTM D 882 with the following exceptions: a. T
31、he width of the specimen shall be 1 inch. b. The initial jaw separation shall be 2 inches and the seam shall be equidistant from each jaw of c. The crosshead speed shall be 2 inches per minute. the testing machine. Care should be taken to insure that seam strength specimens are not removed from poin
32、ts where seal over- lapping has occurred or which were within 1.0 inch (2.54 cm) of either end of the sealer jaw during the sealing operation. Failure of any specimen to meet the requirements of 3.5 shall be cause for rejection of the lot. 4.6 Rejection and retest. Lots which have been rejected may
33、be reworked or replaced to correct the defects and resubmitted for acceptance. Before resubmitting, full particulars concerning previous rejection and the action taken to correct the defects found in the original shall be furnished to the inspector in writing.
