34、 be peened, plugged, impregnated, or welded unless authorized by purchaser. 3.7.5.1 When authorized by purchaser, welding in accordance with AMS2694 or another welding program acceptable to purchaser may be used. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of casting
35、s 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 castings conform to specified requirements. 4.2 Classification of Tests
36、4.2.1 Acceptance Tests Composition (3.1), tensile properties (3.6.1), hardness of production castings (3.6.2), and applicable requirements of quality (3.7) are acceptance tests and shall be performed as specified in 4.3. 4.2.2 Periodic Tests Radiographic soundness (3.7.2) and non-destructive testing
37、 (3.7.3) are periodic tests 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 factor
38、s occurs (4.4.2.2), or when 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 AMS5354F Page 6 of 11 4.3.1 One chemical analysis specimen or a casting from each master heat shall be test
39、ed for conformance 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 inspected and tested to the requirements of the casting drawing and to all technical requirements. 4.3.2.1 Dimensional inspection samp
40、le quantity shall be as specified by purchaser. 4.3.3 Tensile property tests shall be conducted to determine conformance with Table 2. Sampling and test frequency is dependent upon the type and origin of specimen specified by purchaser (See 3.6) or selected by vendor (See 4.3.3.4). When 3.4.2.1 appl
41、ies, test frequency shall be acceptable to purchaser. 4.3.3.1 For separately-cast specimens in the fully heat treated condition (See 3.5.1), one specimen from each lot shall be tested to 3.6.1. 4.3.3.2 For integrally-cast specimens in the fully heat treated condition (See 3.5.1), two specimens from
42、each lot (See 8.2.9) shall be randomly selected and tested for conformance to 3.6.1. 4.3.3.3 For specimens machined from a casting, one casting shall be randomly selected from each lot and tested after heat treatment in accordance with 3.5 at each location shown on the engineering drawing for confor
43、mance 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 purch
44、aser and vendor. 4.3.3.4 When acceptable to purchaser, specimens machined from a casting may be used in lieu of both separately-cast and integrally-cast specimens, and integrally-cast specimens may be used in lieu of separately-cast specimens. In each case, the resultant properties must conform to r
45、equirements of 3.6.1, or to alternative requirements specified by purchaser (8.6). 4.3.3.4.1 When specimens are selected for test as in 4.3.3.4 from an origin other than that specified by purchaser, vendor shall include in the report of 4.5 a description of the origin of the specimen that was tested
46、. 4.3.3.5 When casting size, section thickness, gating method, or other factors do not permit conformance with 4.3.3.2 or 4.3.3.3, sampling and testing shall be agreed upon by purchaser and vendor. 4.3.4 Castings shall be inspected in accordance with 3.7 to the methods, frequency, and acceptance sta
47、ndards specified by purchaser. 4.3.5 Castings in the heat treated condition of 3.5 for delivery shall be tested for hardness to determine conformance to 3.6.2. Unless otherwise specified by purchaser, the number of castings from each lot shall be in accordance with Table 3. SAE AMS5354F Page 7 of 11
