QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of tubing shall supply 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 de

32、emed necessary to ensure that the tubing conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties (3.3.1), leak test (3.4.3) and tolerances (3.5) are acceptance tests and, except for composition, shall be performed on each inspectio

33、n lot. 4.2.2 Periodic Tests Flattening (3.3.2), flarability (3.3.3), and hydraulic strength (3.3.4) are periodic tests and shall be performed at a frequencyselected by the vendor unless frequency of testing is specified by purchaser. 4.3 Sampling and Testing Shall be in accordance with AMS2355 and t

NOTES 8.1 A change bar ( l ) located in the left margin is for the convenience of the user in locating areas where tech

40、nical 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 technical revisions. Change bars and (R) are not used in original publications, nor in documents tha

41、t contain editorial changes only. 8.2 Prior to use, tubing should be cleaned and chemically film treated to increase corrosion resistance. Metallic flakes or particles should not be collected by a clean black cloth when it is drawn through the length of the bore of a sample tube. Discoloration of th

42、e cloth without the presence of flakes or grit is acceptable. 8.3 A double flare is similar to a standard single flare except that the flare is folded back on itself such that the cut edge is inside the flare near the ID of the tube. Definitions and illustration of single flaring are shown in MS3358

43、4; double flaring is defined and illustrated in MS33583. 8.4 Terms used in AMS are clarified in ARP1917. 8.5 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 equi

44、valents of the primary units and are presented only for information. 8.6 Purchase documents should specify not less than the following: AMS4071MSize of tubing desired Quantity of tubing desired. 8.7 Similar Specifications Federal WW-T-700/4, Temper 0, O is listed for information only and shall not be construed as an acceptable alternate unless all requirements of this AMS are met.
