These specimens shall be selected from the same location in the production lot or sample as those tested previously in accordance with AMS2355. 3.3.3.3 Bending Produ
32、ct shall withstand, without cracking, bending at room temperature through an angle of 180 degrees around a diameter equal to the bend factor shown in Table 3 times the nominal thickness of the product with axis of bend parallel to the direction of rolling. 3.4 Quality The product, as received by pur
33、chaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the product. 3.5 Tolerances Shall conform to all applicable requirements of ANSI H35.2 or ANSI H35.2M.

34、PROVISIONS 4.1 Responsibility for Inspection The vendor of the product 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 pro
35、duct conforms 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), response to heat treatment (3.3.2.1), and tolerances (3.5) are acceptance tests and, except for composition, shall
36、be performed on each lot. Response to re-heat treatment (3.3.3.1) is an acceptance test when specified by purchaser. 4.2.2 Periodic Tests Bending as solution heat treated and naturally aged (3.3.1.2) and after response to heat treatment (3.3.2.2 or 3.3.3.2) are periodic tests and shall be performed
37、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. 4.4 Reports The vendor of the product shall furnish with each shipment a report stating that the product conforms to the composition and toleranc
38、es, showing the numerical results of tests on each inspection lot to determine conformance to the acceptance test requirements and stating that the product conforms to the other specified requirements. This report shall include the purchase order number, inspection lot number, AMS4026M, size and qua
39、ntity. The report shall also identify the producer, the mill product form, and the mill produced size. 4.5 Resampling and Retesting Shall be in accordance with AMS2355. 5. PREPARATION FOR DELIVERY 5.1 Identification Shall be in accordance with ASTM B 666/B 666M. 5.2 Protective Treatment Product shal
