18、d directly without refining for pouring of castings. Melting of revert creates a new master heat. 3.2.1.1 The metal for castings and specimens shall be melted and poured under vacuum without loss of vacuum between melting and pouring. When authorized by purchaser, protective atmosphere may be used i

19、n lieu of vacuum for pouring of castings.

25、ed, specimen size and location shall be agreed upon by purchaser and vendor (See 8.2.9 and 8.3). 3.5 Heat Treatment: Not applicable. SAE AMS 5401C Page 5 of 11 3.6 Properties: Conformance shall be based upon testing of separately-cast specimens unless purchaser specifies integrally-cast specimens or

Castings shall be free of cracks, laps, hot tears, cold shuts, and f

29、ree of scale and other process-induced surface contamination which would obscure defects. 3.7.2 Castings shall be produced under radiographic control. This control shall consist of radiographic examination of each casting part number until foundry manufacturing controls in accordance with 4.4.2 have

30、 been established. Additional radiography shall be conducted in accordance with the frequency of inspection specified by purchaser, or as necessary to ensure continued maintenance of internal quality. 3.7.2.1 Radiographic inspection shall be conducted in accordance with ASTM E 1742 or other method s

31、pecified by purchaser. 3.7.3 When specified, castings shall be subjected to fluorescent penetrant inspection in accordance with ASTM E 1417 or other method specified by purchaser. 3.7.4 Acceptance standards for radiographic, fluorescent penetrant, visual, and other inspection methods shall be as agr

32、eed upon by purchaser and vendor (See 8.2.9).

33、hod of inspection. SAE AMS 5401C Page 6 of 11 3.7.5 Castings shall not be peened, plugged, impregnated, or welded unless authorized by purchaser. 3.7.5.1 When authorized by purchaser, welding in accordance with AMS 2694 or other welding program acceptable to purchaser may be used. 4. QUALITY ASSURAN

34、CE 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. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the c

35、astings conform to specified requirements. 4.2 Classification of Tests: 4.2.1 Acceptance Tests: Composition (3.1), room temperature tensile properties (3.6.1), 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: Radi

36、ographic soundness (3.7.2) is a periodic test and shall be performed at a frequency selected by the 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 ch

37、ange in control factors 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

38、 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 tested to requirements of the casting drawing and to all technical requirements. 4.3.2.1 Dimensional inspection sample quantity shall be

39、 as specified by purchaser. 4.3.3 Tensile property tests shall be conducted to determine conformance with 3.6.1. 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, spe

40、cimen source and test frequency 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 3.6.1. SAE AMS 5401C Page 7 of 11 4.3.3.2 For integrally-cast specimens in the as-cast condition, tw

41、o specimens shall be randomly selected from each lot (See 8.2.10) and tested for conformance to properties specified by purchaser (See 3.6 and 8.3). 4.3.3.3 For specimens machined from a casting, one casting shall be randomly selected from each lot and tested in the as-cast condition locations shown

42、 on the engineering drawing for conformance to properties specified by purchaser (See 3.6 and 8.3). 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 4.4.2.2, test locati

43、ons 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 separately-cast and integrally-cast specimens, and integrally-cast specimens may be used in lieu of separately-cast specimens. In each cas

44、e, the resultant properties shall conform to the alternate requirements specified by purchaser (See 8.3). If alternate requirements are not specified, the resultant properties shall conform to the requirements of 3.6 for separately-cast specimens. 4.3.3.4.1 When specimens are selected for test as in

45、 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 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, samp

46、ling 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 standards specified by purchaser. 4.4 Approval: 4.4.1 Sample casting(s) from new or reworked master patterns produced under the casting pr

47、ocedure 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 m

48、eeting 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

49、the proposed change for purchaser reapproval. When requested, vendor shall also submit test specimens, sample castings, or both to purchaser for reapproval. 4.4.2.1 Production castings produced prior to receipt of purchasers approval shall be at vendors risk. SAE AMS 5401C Page 8 of 11 4.4.2.2 Control factors for producing castings and separately-cast specimens include, but are not limited to, the following fa
