SAE INTERNATIONAL AMS5390G Page 5 of 9 3.7.4 Acceptance standards for radiographic, fluorescent penetrant, visual, and other inspection methods shall be as agreed upon by purchaser and vendor (See 8.2.9). AMS2175 may be used to specify acceptance standar
33、ds (casting grade) and frequency of inspection (casting class). 3.7.4.1 When acceptance standards are not specified, Grade C of AMS2175 as applicable to steel castings shall apply for each specified method of inspection. 3.7.5 Castings shall not be peened, plugged, impregnated, or welded unless auth

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection The vendor of castings shall supply all samples for vendors tests and shall be
35、 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 4.2.1 Acceptance Tests Composition (3.1), elevated temper
36、ature tensile properties (3.6.2), hardness (3.6.3.1), and the applicable requirements of quality (3.7) are acceptance tests and shall be performed as specified in 4.3. 4.2.2 Periodic Tests Response to heat treatment (3.5), room temperature tensile properties (3.6.1), and radiographic soundness (3.7.
37、2) are periodic tests and shall be performed at a frequency selected by the vendor unless 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
38、 occurs (4.4.2.2), and 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: 4.3.1 One chemical analysis specimen or a casting from each master heat shall be tested for conformance with Ta
39、ble 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 requirements of the casting drawing and to all technical requirements. 4.3.2.1 Dimensional inspection sample quantity shall be as specified by purchas
40、er. 4.3.3 Tensile property tests shall be conducted to determine conformance with 3.6.2. Sampling and test frequency is dependent upon the type and origin of the 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, specimen source and test fr
41、equency shall be acceptable to purchaser. 4.3.3.1 For separately-cast specimens in the as-cast condition, one specimen from each master heat shall be tested for conformance to Table 3. SAE INTERNATIONAL AMS5390G Page 6 of 9 4.3.3.2 For integrally-cast specimens in the as-cast condition, two specimen
42、s shall be randomly selected from each lot (See 8.2.10) and tested for conformance with properties specified by purchaser (See 8.5). 4.3.3.3 For specimens machined-from-casting, one casting shall be randomly selected from each lot and tested in the as-cast condition at each location shown on the eng
43、ineering drawing for conformance with properties specified by purchaser (See 8.5). 4.3.3.3.1 When size and location of specimens are not shown, two specimens shall be tested, one from the thickest section and one from the thinnest section. Once established under test locations may be changed only as
44、 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 separately-cast and integrally-cast specimens, and integrally-cast specimens may be used in lieu of separately-cast specimens. In each case, the resultant propertie
45、s shall conform to the requirements of 3.6 or to alternative requirements specified by purchaser (See 8.5). 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 source of the
46、 specimen that was tested. 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, freq
47、uency, and acceptance standards specified by purchaser. 4.3.5 One casting or representative specimen from each master heat shall be tested for hardness to determine conformance with 3.6.3.1. 4.4 Approval 4.4.1 Sample casting(s) from new or reworked master patterns produced under the casting procedur
48、e 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 will consistently produce castings and test specimens meeting
49、 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 statement of the proposed change for purchaser reapproval. When requested, vendor shall also submit test specimens, sample castings, o
