If during retesting anadditional quality parameter is observed to be defective, the lotof 50 is subject to rejection for that ca

36、use. The manufacturer ispermitted to test each coil in the failed lot for the property inwhich failure occurred and reject only the nonconformingcoils.11. Inspection11.1 Unless otherwise specified in the contract or purchaseorder, the producer is responsible for the performance of allinspection and

37、test requirements of this specification.

38、rchaser shall have the right to perform any of theinspections and tests set forth in this specification when suchinspections and tests are deemed necessary to ensure that thematerial conforms to prescribed requirements.12. Rejection and Rehearing12.1 Material that fails to conform to the requirement

39、s ofthis specification shall be rejected. Rejections shall be reportedto the producer or supplier promptly and in writing. In case ofdissatisfaction with the results of the test, the producer orsupplier may make claim for a rehearing.12.2 The material must be adequately protected and cor-rectly iden

40、tified in order that the producer may make a properinvestigation.13. Certification13.1 When specified in the purchase order or contract, aproducers or suppliers certification shall be furnished to thepurchaser that the material was manufactured, sampled, tested,and inspected in accordance with this

41、specification and hasbeen found to meet the requirements. When specified in thecontract or purchase order, a report of the test results shall befurnished.14. Packaging, Marking, and Loading14.1 Marking shall be by a tag securely attached to each coilof wire and shall show the identity of the produce

42、r, size of wire,type of coating, class of coating (if applicable), and ASTMdesignation.14.2 Packaging of the coils of wire shall be by agreementbetween the producer and the purchaser. This agreement mayinclude coil dimensions and weight.14.3 Unless otherwise specified, the packaging, marking,and loa
