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. Purchaser reserves the right to sample and to perform any confirmatory testing deemed neces

39、sary to ensure that the castings conform to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1), tensile properties of specimens cut from castings (3.6.1.1) or, when specified, tensile properties of separately-cast specimens (3.6.1.2), and quality (3.7) are a

40、cceptance tests and shall be performed to represent each melt or heat treat lot as applicable. SAE INTERNATIONAL AMS4223E Page 6 of 8 4.2.2 Periodic Tests Stress-corrosion resistance (3.6.2) and radiographic inspection (3.7.3) following the establishment of process control factors (4.4.2) are period

41、ic tests 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 prior to or on the first-article shipment of a casting to a purchaser, when

42、 a change in material and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing Shall be in accordance with the following: 4.3.1 One chemical analysis specimen from each melt for conformance to 3.1. 4.3.2 One or more pre

43、production castings of each casting part number in accordance with 4.4.1. 4.3.3 Not less than four tensile specimens machined from a casting or castings from each heat treat lot except when purchaser specifies use of separately-cast specimens. If specimen locations are not shown on the drawing, not

44、less than two specimens from the thickest section and not less than two specimens from the thinnest section, shall be cut from a casting or castings from each heat treat lot. 4.3.4 One separately-cast tensile specimen in accordance with 3.4.2 representing each lot when purchaser specifies use of sep

45、arately-cast specimens, except when properties of specimens cut from castings are specified. 4.3.5 Specimens for stress-corrosion tests shall be tensile specimens taken from the same areas of castings as for tensile tests of specimens cut from castings. Whenever practicable, specimens shall be not l

46、ess than 0.250 inch (6.35 mm) diameter at the reduced parallel gage section. If tensile specimens are not cut from castings but are separately cast, the stress-corrosion specimen can be taken from the separately-cast tensile specimens. 4.4 Approval 4.4.1 Sample castings from new or reworked tooling

47、(i.e., patterns, molds, dies, etc.) and the casting procedure shall be approved by purchaser before castings for production use are supplied, unless such approval be waived by purchaser. 4.4.2 Vendor shall establish, for production of sample castings of each part number, parameters for process contr

48、ol factors which will produce acceptable castings; these shall constitute the approved casting procedure and shall be used for producing production castings. Vendor shall also establish a procedure for production of separately-cast tensile specimens, but these control factors need not be identical t

49、o those used for production of castings. Method for production of separately-cast tensile specimens shall be consistent for all material cast to this specification. If necessary to make any change in parameters for process control factors, vendor shall submit for reapproval a statement of the proposed changes in processing and, when requested, sample castings, test specimens, or bot
