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)
33、 with a relative humidity of 30 to 50% using a frequency of 10 to 50 Hz. The test specimens shall meet the following requirements:4.3.2.1 Fatigue Specimen DesignFatigue samples shall be machined to ASTM E466, Figure 1. The specimen shall have a 0.500 inch (12.70 mm) gage diameter, a 2.00 inch (50.80
