42、, tensile properties (3.6.1), intermediate hardness (3.6.2.1), final hardness (3.6.2.2) and applicable requirements of quality (3.7) are acceptance tests and shall be performed as specified in 4.3. 4.2.2 Periodic Tests Corrosion resistance (3.7.1.1) and radiographic soundness (3.7.2) are periodic te
43、sts and shall be performed at a frequency selected by vendor, unless frequency of testing is specified by purchaser. 4.2.3 Preproduction Tests All technical requirements are preproduction tests and shall be performed on sample castings (4.3.2), when a change in control factors occurs (4.4.2.2), or w
44、hen purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing The minimum testing performed by vendor shall be in accordance with the following: SAE INTERNATIONAL AMS5353E Page 6 of 11 4.3.1 One chemical analysis specimen or a casting from each master heat shall be tested for con
45、formance with Table 1. If 3.4.2.1 applies, test frequency shall be acceptable to purchaser. 4.3.2 One preproduction casting in accordance with 4.4 shall be tested to the requirements of the casting drawing and to all technical requirements. 4.3.2.1 Dimensional inspection sample quantity shall be as
46、specified by purchaser. 4.3.3 Tensile tests shall be conducted to determine conformance with Table 2. Sampling and test frequency are dependent upon the type and origin of specimen specified by purchaser (See 3.4.4 and 3.6) or selected by vendor (See 4.3.3.4). When 3.4.2.1 applies, test frequency sh
47、all be acceptable to purchaser. 4.3.3.1 For separately-cast specimens in the fully heat treated condition (See 3.5.2), one specimen from each master heat shall be tested to 3.6.1. 4.3.3.2 For integrally-cast specimens in the fully heat treated condition (See 3.5.2), two specimens from each lot (See
48、8.2.10) shall be randomly selected and tested for conformance to properties specified by purchaser (See 3.6 and 8.6). 4.3.3.3 For specimens machined-from-casting, one casting shall be randomly selected from each lot and tested in the fully heat treated condition (See 3.5.2) at each location shown on
49、 the engineering drawing for conformance to the properties specified by purchaser. 4.3.3.3.1 When size and location of specimens are not shown, two test specimens shall be tested, one from the thickest section and one from the thinnest section. Once established under 4.4.2.2, test locations may be changed only as agreed upon by purchaser and vendor. 4.3.3.4 When acceptable
