28、f the castings. Castings shall be free of cracks, laps, hot tears, and cold shuts, and free of scale and other process induced surface contamination which would obscure defects. 3.7.1.1 Unless otherwise specified, castings shall be sufficiently cleaned such that, after passivation by purchaser, the
29、castings shall meet the corrosion test requirement of AMS2700. 3.7.2 Castings shall be produced under radiographic control.

32、rchaser. 3.7.4 Acceptance standards for radiographic, fluorescent penetrant, magnetic particle, visual, and other inspection methods shall be agreed upon by purchaser and vendor (See 8.2.8). AMS2175 may be used to specify acceptance standards (casting grade) and frequency of inspection (casting clas
33、s). 3.7.4.1 When acceptance standards are not specified, Grade C of AMS2175 as applicable to steel castings shall apply for each applicable method of inspection. 3.7.5 Castings shall not be peened, plugged, impregnated, or welded unless authorized by purchaser. 3.7.5.1 When authorized by purchaser,
34、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 castings shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. P
35、urchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the castings conform to specified requirements. SAE INTERNATIONAL AMS5362L Page 4 of 9_ 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties (3.6.1), and
36、the applicable requirements of quality (3.7) are acceptance tests and shall be performed as specified in 4.3. 4.2.2 Periodic Tests Embrittlement (3.6.2), corrosion resistance (3.7.1.1), and radiographic soundness (3.7.2), are periodic tests and shall be performed at a frequency selected by vendor un
37、less a 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), and when purchaser deems confirmatory testing to be required. 4.3
38、Sampling and Testing The minimum testing performed by vendor shall be in accordance with the following: 4.3.1 One chemical analysis specimen or a casting from each master heat shall be tested for conformance with Table 1; if 3.4.2.1 applies, test frequency shall be acceptable to purchaser. 4.3.2 One
39、 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 specified by purchaser. 4.3.3 Tensile tests shall be conducted to determine conformance with Table 2.
40、 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 shall be acceptable to purchaser. 4.3.3.1 For separately-cast specimens in the solution heat treated co
41、ndition of 3.5.1, one specimen from each master heat shall be tested for conformance to 3.6.1. 4.3.3.2 For integrally-cast specimens in the solution heat treated condition of 3.5.1, two specimens from each lot (See 8.2.9) shall be randomly selected and tested for conformance to 3.6.1. 4.3.3.3 For sp
42、ecimens machined from casting, one casting shall be randomly selected from each lot and tested after solution heat treatment in conformance with 3.5.1.1 at locations shown on the engineering drawing for conformance with 3.6.1. 4.3.3.3.1 When size and location of specimens are not shown, two test spe
43、cimens 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 to purchaser, specimens machined from casting may be used in lieu of both separa
44、tely-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 requirements of 3.6, or to alternative requirements specified (See 8.2.3) by purchaser. 4.3.3.4.1 When specimens are selecte
45、d 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. 4.3.3.5 When casting size, section thickness, gating method, or other factors do not permit conformance to 4.3.3.2 or
46、 4.3.3.3, sampling and testing shall be agreed upon by purchaser and vendor. SAE INTERNATIONAL AMS5362L Page 5 of 9_ 4.3.4 Castings shall be inspected in accordance with 3.7 to the methods, frequency, and acceptance standards specified by purchaser. 4.4 Approval 4.4.1 Sample casting(s) from new or r
47、eworked master patterns produced under the casting procedure of 4.4.2 shall be approved by purchaser before castings for production use are supplied, unless such approval be waived by purchaser. 4.4.2 For each casting part number, vendor shall establish parameters for process control factors that wi
48、ll consistently produce castings and test specimens meeting the requirements of the casting drawing and this specification. These parameters shall constitute the approved casting procedure and shall be used for production of subsequent castings and test specimens. If necessary to make any change to these parameters, vendor shall submit a state
