SAE AMS3220G Page 4 of 6 4.2 Classification of Tests 4.2.1 Acceptance Tests Tests for the following requirements are accept

    22、ance tests and shall be performed on each lot: TABLE 1 Requirement Paragraph Reference Hardness, Original Properties 3.2.1.1 Elongation, Original Properties 3.2.1.2 Elongation Change in Oil 3.2.2.2 Volume Change in Fuel 3.2.3.2 4.2.2 Qualification Tests Qualification testing shall consist of all of

    23、the physical property requirements listed in 3.2 and shall be performed prior to certification of materials to this specification, when a change in ingredients and/or processing requires reapproval as in 4.5.2, and/or when purchaser deems confirmatory testing to be required. 4.2.3 Test Samples 4.2.3

    24、.1 For qualification testing, specimens shall be prepared from 6 inch (152 mm) square by 0.075 inch 0.008 (1.90 mm 0.20) thick molded test slabs per ASTM D 3182 compounded for the same intended curing process as the end product. 4.2.3.2 For acceptance testing, sufficient material shall be taken at r

    25、andom from each lot of product to provide specimens to perform all required tests. The number of determinations for each requirement shall be as specified in the applicable test procedure or, if not specified therein, not less than three. If specimens cannot be prepared from the product, test specim

    26、ens prepared from the same batch of material and in the same state of cure as the product shall be used. At a minimum, specific gravity tests shall be conducted on the end item or a section removed from the end item (except as noted in 4.2.3.2.3). 4.2.3.2.1 When the product supplied is an extrusion

    27、of such shape that suitable test specimens cannot be cut from the product, a separate extruded flat strip test sample, 0.075 inch 0.008 (1.90 mm 0.20) thick, produced from the same production batch of compound, in the same state of cure as the product being supplied, shall be used to prepare test sp

    28、ecimens. 4.2.3.2.2 When the product is a molded item of such shape that suitable test specimens cannot be cut, a slab 6 inches (152 mm) square by 0.075 inch 0.008 (1.90 mm 0.20) thick per ASTM D 3182, molded from the same batch of compound, in the same state of cure as the product being supplied, sh

    29、all be used to prepare test specimens. 4.2.3.2.3 When the mixer of the material is not the actual manufacturer of the end product, specimens shall be prepared from 6 inch (152 mm) square by 0.075 inch 0.008 (1.90 mm 0.20) thick molded test slabs per ASTM D 3182, catalyzed and cured to an optimum sta

    30、te of cure. 4.2.3.3 Specimen Test Values All individual specimen test result values used to determine pass/fail criteria must be within acceptable limits as indicated in 3.2. Where test methods dictate that results be reported as average or median values, failed values shall not be allowed in these

    31、determinations. SAE AMS3220G Page 5 of 6 4.2.3.3.1 If any specimen fails to meet the pass/fail criteria as listed in Table 1, a retesting of three (3) additional specimens with acceptable results for each nonconforming specimen, shall be necessary for acceptance. The same material batch as was used

    32、for the failed test shall be used for retesting. Failure of any retest specimen shall be cause for rejection of the batch along with the rejection of any product that may have been produced from the batch. Results of all tests shall be reported. Records of all rejections shall be maintained. 4.3 Ind

    33、ividual specimen failures that occur due to obvious flaws in the specimen itself or because of mechanical failure of the test equipment, may be disregarded with only a single retest specimen required for acceptance. All such occurrences must be recorded. 4.4 Sampling When a statistical sampling plan

    34、 for product acceptance has been agreed upon by purchaser and vendor, sampling shall be in accordance with such plan and the report of 4.6 shall state that such plan was used.
