QUALITY ASSURANCE PROVISIONS

    25、4.1 Responsibility for InspectionThe producer of castings shall supply all samples for producers 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 castings confo

    26、rm to specified requirements.4.2 Classification of Tests4.2.1 Acceptance TestsAll technical requirements except radiographic inspection (3.5.3) are acceptance tests and shall be performed on each lot (see 4.2.2).4.2.2 Periodic TestsRadiographic inspection (3.5.3) following establishment of process c

    27、ontrol (4.4.2) is a periodic test and shall be performed at a frequency determined by the producer to ensure continued maintenance of internal quality, unless frequency is specified by purchaser (see 3.5.2).4.2.3 Preproduction TestsAll technical requirements are preproduction tests and shall be perf

    28、ormed 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 required.4.3 Sampling and TestingShall be in accordance with the following:4.3.1 At least one

    29、chemical analysis specimen from each melt for conformance to 3.1 unless another sampling frequency is agreed upon by purchaser and producer.4.3.2 One or more preproduction castings of each casting part number in accordance with 4.4.1.4.4 Approval4.4.1 Sample castings from new or reworked dies and th

    30、e casting procedure shall be approved by purchaser before castings for production use are supplied, unless such approval be waived by purchaser.4.4.2 Producer shall establish, for production of sample castings of each part number, parameters for process control factors which will produce acceptable

    31、castings and, when requested, sample castings and/or radiographic results; these shall constitute the approved casting procedure and shall be used for producing production castings. If necessary to make any change in parameters for process control factors, producer shall submit for reapproval a stat

    32、ement of the proposed change in processing and, when requested, sample castings. Production castings incorporating the revised operations shall not be shipped prior to receipt of reapproval.SAE INTERNATIONAL AMS4290M Page 5 of 64.4.2.1 Control factors for producing castings include, but are not limi

    34、28 q C) from the established limit is permissibleSolidification and cooling proceduresStraightening procedure, when applicableCleaning operationsMethods of inspectionRadiographic inspection sampling plan, if used.4.4.2.1.1 Any of the above process control factors for which parameters are considered

    35、proprietary by the producer may be assigned a code designation. Each variation in such parameters shall be assigned a modified codedesignation.4.5 ReportsThe producer of castings shall furnish with each shipment a report showing the results of tests for composition of each melt and stating that the

    36、castings conform to the other technical requirements. This report shall include the purchase order number, melt and lot number, AMS4290M, part number, and quantity.4.6 Resampling and RetestingIf any specimen used in the above tests fails to meet the specified requirements, disposition of the casting

    37、s may be based on the results of testing two additional specimens for each original nonconforming specimen. Failure of any retest 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 DELIVERY5.

    38、1 IdentificationShall be in accordance with AMS2804.5.1.1 Impregnated castings shall be marked “IMP“.5.2 PackagingCastings shall be prepared for shipment in accordance with ASTM B660 and in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of

    39、the castings to ensure carrier acceptance and safe delivery.6. ACKNOWLEDGMENTA producer shall mention this specification number and its revision letter in all quotations and when acknowledging purchase orders.7. REJECTIONSCastings not conforming to this specification, or to modifications authorized

    40、by purchaser, will be subject to rejection.SAE INTERNATIONAL AMS4290M Page 6 of 68. NOTES8.1 Revision IndicatorA change bar (l) located in the left margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of th

    41、is document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are not used in original publications, nor in documents that contain editorial changes only.8.2 Terms used in AMS are clarified in ARP1917 an

    42、d as follows:8.2.1 MeltA single homogeneous batch of molten metal to which all melt additions and processing have been completed and from which castings are poured.8.2.2 Melt LotCastings poured from a single melt.8.3 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are p

    43、rimary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.8.4 Purchase documents should specify not less than the following:AMS4290MPart number or die number of castings desiredQuant

    44、ity of castings desiredAcceptance standards for nondestructive inspection (see 3.5.1) plus method and frequency of inspection (see 3.5.2) when required.8.5 Similar SpecificationsAMS-QQ-A-591, Alloy 360.0 or 413.0 is listed for information only and shall not be construed as an acceptable alternate unless all requirements of this AMS are met.PREPARED BY AMS COMMITTEE “D”
