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

32、sary to ensure that the castings conform to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1) and tensile properties (3.6.1) are acceptance tests and shall be performed to represent each melt or heat treat lot as applicable. SAE INTERNATIONAL AMS4214J Page

33、5 of 7 4.2.2 Periodic Tests Radiographic inspection (3.7.3) following establishment of process control (4.4.2) is a periodic test and shall be performed at a frequency determined by the vendor to ensure continued maintenance of internal quality unless frequency of testing is specified by purchaser.

34、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 a change in material and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be

35、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 separately-cast tensile specimens in accordance with 3.4.2 from each heat treat lot unless purchaser specifies that specimens be

38、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 the process control factors which will produce acceptable castings; these shall cons

39、titute 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. Method for production of separately cast tensile specimens shall be consistent for all material cast to this specifi

40、cation. Control factors for producing separately-cast tensile specimens need not be the same as those used for production of castings. If necessary to make any change in parameters for the process control factors, vendor shall submit for reapproval a statement of the proposed changes in processing a

41、nd, when requested, test specimens, sample castings, or both. Production castings incorporating the revised operations shall not be shipped prior to receipt of reapproval. SAE INTERNATIONAL AMS4214J Page 6 of 7 4.4.2.1 Control factors for producing castings include, but are not limited to, the follo

45、t least one casting or of separately-cast specimens from each melt and the results of tests for tensile properties of separately-cast specimens representing each lot or, when specified, of specimens cut from castings from each lot. This report shall include the purchase order number, lot number, AMS

46、4214J, part number, and quantity. 4.6 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the castings may be based on the results of testing two additional specimens for each original nonconforming specimen. Failure of any retest

47、 specimen to meet the specified requirements shall be cause for rejection of the castings represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification Shall be in accordance with AMS2804. 5.1.1 Impregnated castings shall be marked “IMP” (see 3.7.5) 5.2 Packagin
