SAE INTERNATIONAL AMS4080P Page 6 of 7 4.2.2 Periodic Tests Flattening (3.3.2.2) and flarability (3.3.2.3) as annealed are periodic tests and shall be performed at a frequency selected by the producer unless
37、frequency of testing is specified by purchaser. 4.3 Sampling and Testing Shall be in accordance with AMS2355. Specimens for flarability test (3.3.2.3) shall be full tubes or sections cut from tubes. The end of the specimen to be flared shall be cut square, with the cut end smooth and free from burrs
38、, but, except for sizes 0.375 inches (9.52 mm) and under, not rounded. 4.4 Reports The producer of tubing shall furnish with each shipment a report stating that the tubing conforms to the composition and showing the numerical results of tests to determine conformance to the other acceptance test req
39、uirements and when performed to the periodic tests. This report shall include the purchase order number, inspection lot number, AMS4080P, size, and quantity. The report shall also include the manufacturer and size of the mill product. 4.4.1 When the product size is outside the range covered by Table
40、 2 or Table 6, the report shall contain a statement to that effect. 4.5 Resampling and Retesting Shall be in accordance with AMS2355. 5.

41、amage during storage and shipment by a method determined by producer unless specified by purchaser. Examples of typical protective methods include but are not limited to interleaving with paper or oiling of the surface. Product produced under this specification shall not be oiled. 5.2.2 Tubing shall
42、 be prepared for shipment in accordance with ASTM B660 and in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of the tubing to ensure carrier acceptance and safe delivery. 6. ACKNOWLEDGMENT A producer shall mention this specification number
43、and its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Tubing not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. SAE INTERNATIONAL AMS4080P Page 7 of 7 8. NOTES 8.1 Revision Indicator A change bar
44、(l) located in the left margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including techni
45、cal revisions. Change bars and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Terms used in AMS are clarified in ARP1917 and defined as follows: A double flare is similar to a standard single flare except that the flare is folded back on itself s
46、uch that the cut edge is inside the flare near the ID of the tube. Definition and illustration of single flaring is shown in MS 33584; double flaring is defined and illustrated in MS 33583. 8.3 Hardness should not be lower than 85 HRE, determined in accordance with ASTM E18. Hardness has been used t
47、o verify that tubing is properly processed, but an out-of-specification hardness number is not always indicative of product with out of specification tensile strength. Further analysis including material composition verification, heat treat process parameter review, and/or tensile property measureme
