13、, arsenic, antimony, tin, and manganese shall not exceed 0.0040% (40 ppm). 3.2 Condition Cold-drawn or cold-rolled, annealed, and cleaned. SAE INTERNATIONAL AMS4700D Page 3 of 5 3.3 Properties Wire shall conform to the following requirements: 3.3.1 Resistivity The weight resistivity, determined in a
14、ccordance with ASTM B 193, shall not exceed 0.15328 ohm-gram per square meter at 68 F 4 (20 C 2), which corresponds to a conductivity of not less than 100% IACS (International Annealed Copper Standard) (58 MS/m). 3.3.2 Embrittlement Wire shall withstand a minimum of 10 bends without cracking or brea
15、king, when tested as in 3.3.2.1 and then subjected to additional bending until failure occurs. 3.3.2.1 Specimens shall be cleaned by any suitable method and then heated at 1562 F 45 (850 C 25) for not less than 30 minutes in an atmosphere containing not less than 10% hydrogen. Specimen shall then be
16、 clamped between jaws having edge radii equal to 2.5 times the nominal diameter of the wire. Specimen, held under a tension of approximately 3000 psi (21 MPa), shall be bent 90 degrees over the edge of one jaw and returned to its initial position; this constitutes one bend. Specimen shall then be be
17、nt 90 degrees in the reverse direction and returned to its initial position; this constitutes another bend. Each bend shall be made in the opposite direction from that of the preceding bend. 3.3.2.1.1 Specimens shall be examined at the bend after 10 bends and at the broken area after failure under 1
18、0X magnification. The bend shall have no surface cracks or blisters. The break shall show a necked-down section, characteristic of a ductile material, with no evidence of grain faces or boundaries. 3.3.3 Microstructure Specimens, prepared as specified in ASTM E 3, from wire heated as in 3.3.2.1, whe
19、n suitably etched to reveal the structure and examined at 100X magnification, shall show no evidence of copper oxide or other inclusions. 3.4 Quality Wire, as received by purchaser, shall be uniform in quality and condition, sound, smooth, and free from foreign materials and from imperfections detri
20、mental to usage of the wire. 3.5 Tolerances Shall conform to AMS2224. 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 reserves the right to sa
21、mple and to perform any confirmatory testing deemed necessary to ensure that the wire conforms to the specified requirements. 4.2 Classification of Tests All technical requirements are acceptance tests and shall be performed on each lot. 4.3 Sampling and Testing Shall be in accordance with ASTM B 25
22、0/B 250M. SAE INTERNATIONAL AMS4700D Page 4 of 5 4.4 Reports The vendor of wire shall furnish with each shipment a report showing the results of tests to determine conformance to all technical requirements. This report shall include the purchase order number, lot number, AMS4700D, size, and quantity
23、. 4.5 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the wire may be based on the results of testing three additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified re
24、quirements shall be cause for rejection of the wire represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Wire shall be supplied on spools or in coils except when straight lengths are ordered. 5.2 Identification 5.2.1 Spools and Coils Shall be legibly marked, by a dura
25、ble tag or label, with not less than the manufacturers identification, purchase order number, AMS4700D, nominal size, and quantity; boxes or drums shall be marked with the same information. 5.2.2 Straight Lengths Shall have attached to each bundle or enclosed in each box a durable tag or label legib
26、ly marked with the information of 5.2.1; when boxed, the box shall be marked with the same information. 5.3 Packaging 5.3.1 Spools and Coils Coils shall be individually wrapped with waterproof paper or packed in waterproof drums. Spools, when ordered, shall be boxed. 5.3.2 Straight Lengths Shall be
27、bundled or boxed. 5.3.3 Wire shall be prepared for shipment in accordance with commercial practice and in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of the wire to ensure carrier acceptance and safe delivery. 6. ACKNOWLEDGMENT A vendor
28、shall include this specification number and its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Wire not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. SAE INTERNATIONAL AMS4700D Page 5 of 5 8. NOTE
