15、all show no evidence of breaking after two strands of wire are twisted around each other ten times per inch (25 mm) of length. 3.4 Quality: Wire, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of
16、 the wire. 3.5 Tolerances: Shall conform to AMS 2224 as applicable to nonrefractory alloys. 4. QUALITY ASSURANCE PROVISIONS: 4.1 Responsibility for Inspection: The vendor of wire shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser
17、reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the wire conforms to specified requirements. 4.2 Classification of Tests: All technical requirements are acceptance tests and shall be performed on each lot. A lot shall consist of all wire from the
18、same heat or melt, drawn at the same time, and presented for acceptance at the same time. 4.3 Sampling and Testing: Shall be in accordance with ASTM B 250 or ASTM B 250M. 4.4 Reports: The vendor of wire shall furnish with each shipment a report showing the results of tests for chemical composition,
19、average grain size, and twisting on each lot and stating that the wire conforms to the other technical requirements. This report shall include the purchase order number, lot number, AMS 4712F nominal size, and quantity. Copyright SAE International Provided by IHS under license with SAENot for Resale
