QUALITY ASSURANCE PROVISIONS4.1 Responsibility for InspectionThe vendor of plate 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 confirmat

29、ory testing deemed necessary to ensure that the plate conforms to the specified requirements.SAE INTERNATIONAL AMS4354 Page 5 of 64.2 Classification of Tests4.2.1 Acceptance TestsComposition (3.1), tensile properties (3.3.1), corrosion resistance (3.3.2), tolerances (3.5), when specified, fatigue re

30、sistance (3.3.5), and when specified, ultrasonic soundness (3.4.1) are acceptance tests and except for composition, shall be performed on each inspection lot.4.2.2 Periodic TestsExfoliation corrosion resistance (3.3.3) and stress corrosion cracking (3.3.4) are periodic tests and shall be performed a

31、t afrequency selected by the vendor unless frequency of testing is specified by purchaser.4.3 Sampling and TestingShall be in accordance with AMS2355 and the following:4.3.1 Tensile TestingTensile specimens shall be taken with axis of specimens parallel to each applicable grain flow direction specif

32、ied in Table 2.4.3.2 Fatigue Resistance TestingTwo specimens for fatigue testing shall be taken from each end of the parent plate in the long transverse grain direction. These specimens are to be removed from the T/2, W/2 location. Fatigue testing shall be conducted in air at 70 F + 5 F (21 C + 3 C)
