24、ndards for radiographic, fluorescent penetrant, 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 class). 3.7.4.1 When acceptance standards are not sp
25、ecified, 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, welding in accordance with AMS2694 or another we
26、lding 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. Purchaser reserves the right to sample and to per
27、form 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), hardness of castings (3.6.1), and the applicable requirements of quality (3.7) are acceptance tests and shall be perform

SAE INTERNATIONAL AMS5387E Page 5 of 8_ 4.4.2.2.1 Any of the control factors for which parameters are considered proprietary by vendor may be assigned a code designation. Each variation in such parameters shall be assigned a modified code designati
41、on. 4.4.2.2.1.1 Unless otherwise agreed upon by purchaser and vendor, purchaser shall be entitled to review proprietary control factor details and coding at vendors facility. 4.5 Reports The vendor of castings shall furnish with each shipment a report showing the results of tests to determine confor
42、mance to the acceptance test requirements, and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, master heat identification, AMS5387E, part number, and quantity. 4.6 Resampling and Retesting If the results of a valid test fail
43、 to meet the requirements, two additional specimens in accordance with 4.3 from the same master heat, modified melt (See 3.2.3), or lot, as applicable, shall be tested for each nonconforming characteristic. The results of each additional test, and the average of the results of all tests (original an
44、d retests) shall meet the specified requirements; otherwise, the master heat or lot shall be rejected.
