23、Responsibility for Inspection The vendor of extrusions 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 deemed necessary to ensure that the extrusions conform
24、to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties as solution heat treated and naturally aged (3.3.1.1), ultrasonic inspection when specified (3.4.1), and tolerances (3.5) are acceptance tests and, except for composition, shall be per

27、sting shall be left to the discretion of the producer. SAE AMS4161H Page 5 of 6 4.4 Reports The vendor of product shall furnish with each shipment a report stating that the product conforms to the composition and tolerances, and showing the numerical results of tests on each inspection lot to determ

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 edit
32、orial 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 that contain editorial chang
33、es only. 8.2 Hardness should be not lower than 55 HB/10/500 or 60 HB/10/1000, determined in accordance with ASTM E 10. Hardness has been used to verify that product is properly processed, but an “out of range hardness number” is not always indicative of product with “out-of-specification tensile str
34、ength”. Further analysis including material composition verification, heat treat process parameter review, and/or tensile property measurement on product with out-of-range hardness may be necessary. 8.3 Terms used in AMS are clarified in ARP1917. 8.4 Dimensions and properties in inch/pound units and
35、 the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. SAE AMS4161H Page 6 of 6 8.5 Purchase documents should specify not less than the followin
36、g: AMS4161H Form and size or section identification number of extrusions desired Quantity of extrusions desired Ultrasonic inspection acceptance standards, when specified (See 3.4.1). Whether Type II tubing is required (Where no type is specified, Type I shall apply) Whether Class 1 or Class 2 solution heat treatment is required. 8.6 Similar Specifications ASTM B 221 and ASTM B 221M are listed for information only and shall not be construed as acceptable alternates unless all requirements of this AMS are met.
