The external and internal surface finishes shall be produced by any method which will result in surfaces free from laps, folds, tears, and extraneous materials and which show no oxide discoloration. Processing shall not aff
16、ect limits of wall thickness or corrosion resistance.3.4 Properties: Tubing shall conform to the following requirements:3.4.1 Tensile Strength: Shall be not lower than 54.0 ksi (372 MPa), determined in accordance with ASTM E 8 or ASTM E 8M.3.4.2 Embrittlement: Specimens of tubing, nominally 6 inches
17、 (152 mm) in length or twice the diameter, whichever is greater, shall withstand, without cracking, the mercurous nitrate test performed in accordance with ASTM B 154, Procedure A, or the Ammonia Vapor Test in accordance with ASTM B 858.3.5 Quality: Tubing, as received by purchaser, shall be uniform
18、 in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the tubing.3.6 Tolerances: Shall conform to AMS 2223 as applicable to nonrefractory alloys.4. QUALITY ASSURANCE PROVISIONS: 4.1 Responsibility for Inspection: The vendor of tubing shall s
19、upply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the tubing conforms to specified requirements.4.2 Classification of Tests: 4.2.1 Acce
20、ptance Tests: Composition (3.1), tensile strength (3.4.1), and tolerances (3.6) are acceptance tests and shall be performed on each lot.4.2.2 Periodic Tests: Embrittlement (3.4.2) is a periodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specified

22、g shall furnish with each shipment a report showing the results of tests for chemical composition and tensile properties, and stating that the tubing conforms to the other technical requirements. This report shall include the purchase order number, lot number, AMS 4558G, nominal size and quantity.4.
23、5 Resampling and Retesting: If any specimen used in the above tests fails to meet specified requirements, disposition of the tubing may be based on the results of testing two additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet specified requirements
