20、ified, shall conform to all applicable requirements of AMS2279. 3.5 Toxicological Formulations The material shall have no adverse effects on the health of personnel when used for its intended purpose in accordance with manufacturers instructions and with appropriate handling procedures. 4. QUALITY A
21、SSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the product 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 tha
22、t the product conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Tests for the following requirements shown in Table 2 are acceptance tests and shall be performed on each lot: TABLE 2 Requirement Paragraph Reference Hardness, as received 3.2.1.1 Tensile Strength,
23、as received 3.2.1.2 Elongation, as received 3.2.1.3 Volume Change in Oil 3.2.2.4 and 3.2.3.2 SAE AMS3222H - 4 -4.2.1.1 Lot A quantity of one size of product processed and packaged as one production entity from a batch. 4.2.1.2 Batch The quantity of compound run through a mill or mixer at one time. 4
24、.2.1.3 Random Sampling The method shall be as specified in the parts standard, drawing or purchase document. If not specified, product shall be taken at random from each lot to perform all the required acceptance tests. The number of test iterations for each requirement shall be specified in the app
25、licable test procedure. 4.2.1.4 Sample shall be from a production batch/lot. 4.2.2 Preproduction Tests All technical requirements are preproduction tests and shall be performed prior to or on the initial shipment of a product to a purchaser, when a change in ingredients and/or processing requires re
26、approval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing Shall be as follows: 4.3.1 For Acceptance Tests Sufficient product shall be taken at random from each lot to perform all required tests. The number of determinations for each requirement shal
27、l be as specified in the applicable test procedure or, if not specified therein, not less than three. 4.3.1.1 If specimens cannot be prepared from the product, ASTM test specimens prepared from the same batch and state of cure shall be used. When the product supplied is an extrusion of such shape th
28、at suitable test specimens cannot be cut from the product, a separate flat strip test sample from the same production lot shall be supplied upon request. This strip shall be prepared from tubing 1.000 inch 0.063 (25.40 mm 1.60) in OD by 0.075 inch 0.008 (1.90 mm 0.20) in wall thickness, mechanically
29、 slit and flattened into a strip while being extruded, and cured in the same manner as production product. When the product is a molded shape from which test specimens cannot be cut, a slab, 6 inches (152 mm) square by 0.075 inch 0.008 (1.90 mm 0.20) thick, molded from the same batch of compound sha
30、ll be supplied upon request. 4.3.1.2 When a statistical sampling plan has been agreed upon by purchaser and vendor, sampling shall be in accordance with such plan in lieu of sampling as in 4.3 and the report of 4.5 shall state that such plan was used.4.3.2 For Preproduction Tests As agreed upon by p
31、urchaser and vendor. 4.4 Approval 4.4.1 Sample product shall be approved by purchaser before product for production use is supplied, unless such approval is waived by the purchaser. Results of tests on production product shall be essentially equivalent to those on the approved sample. SAE AMS3222H -
32、 5 -4.4.2 Vendor shall use ingredients, manufacturing procedures, processes, and methods of inspection on production product which are essentially the same as those used on the approved sample product. If it is necessary to make any change in ingredients, in type of equipment for processing, or in m
33、anufacturing procedures, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample product. Production product made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Reports The supplier of the
34、product shall make readily available a report showing the results of tests to determine conformance to the acceptance requirements and stating that the product conforms to the other technical requirements. This report shall include AMS number with revision, manufacturers identification and product d
35、esignation, batch/lot number and date of manufacture.4.6 Resampling and Retesting If any specimen fails, a retesting of three additional specimens for each nonconforming specimen shall be necessary for product acceptance. Whenever possible the same batch/lot of product as was used for the failed tes
36、t shall be used for retesting. Failure of any retest specimen shall be cause for rejection. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification and Packaging Shall be as specified in the parts standard, drawing or purchase document. If not specified, shall be as fo
37、llows: Packaging shall be in accordance with AMS2810. A lot may be packaged in small quantities and delivered under the basic lot approval provided lot information is maintained. 5.1.1 Each package, box, and shipping container shall be permanently and legibly marked with the following when pertinent
38、:Specification number AMS number with revision, class, grade, and type Manufacturers identification Manufacturers product designation Batch/lot number Date of manufacturing/packaging Shelf life expiration date Storage conditions 6. ACKNOWLEDGMENT A vendor shall mention this specification number and
39、its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Product not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. 8.

40、user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of a specification. An (R) symbol to the left of the document title indicates a complete revision of the specification, including technical revision. Change bars and (R) are not used in orig
41、inal publications, nor in specifications that contain editorial changes only. 8.2 Terms used in AMS are clarified in ARP1917. SAE AMS3222H - 6 -8.3 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius tempera
42、tures 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: AMS3222GForm and size or part number of product desired Quantity of product desired Method of test and acceptance standards for weathering (See 3.2.7) and corrosion (See 3.2.8).
