32、as annealed (3.3.1.1) and after solution and precipitation heat treatment (3.3.2.1), quality (3.4), and tolerances (3.5) are acceptance tests and, except for composition, shall be performed on each inspection lot. 4.2.2 Periodic Tests Flattening (3.3.1.2) and flarability (3.3.1.3) are periodic tests
33、 and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.3 Sampling and Testing Shall be in accordance with AMS2355. Specimens for flarability test (3.3.1.3) shall be full tubes or sections cut from tubes. The end of the specimen to be fl
34、ared shall be cut square, with the cut end smooth and free from burrs, but, except for sizes 0.375 inches (9.52 mm) and under, not rounded. 4.4 ReportsThe vendor of tubing shall furnish with each shipment a report stating that the tubing conforms to the composition and showing the numerical results
35、of tests to determine conformance to the other acceptance test requirements and when performed to the periodic tests. This report shall include the purchase order number, inspection lot number, AMS4080N, size, and quantity. The report shall also include the manufacturer and size of the mill product.

NOTES 8.1 A change bar (|) 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 comple
41、te revision of the document, including technical 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 exce
42、pt that the flare is folded back on itself such 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 isdefined and illustrated in MS 33583. 8.3 Hardness should not be lower than 85 HRE, determined in accorda
43、nce with ASTM E 18. Hardness has been used to 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 paramet
44、er review, and/or tensile property measurement on product with out-of-range hardness may be necessary. 8.4 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary: dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equiva
45、lents of the primary units and are presented only for information. 8.5 Purchase documents should specify not less than the following. AMS4080NSize of tube desired Quantity of tube desired. 8.6 Similar Specifications Federal WW-T-700/6, Temper O, is listed for information only and shall not be construed as an acceptable alternate unless all requirements of this AMS are met.
