32、ty for Inspection The fluid supplier shall supply all samples for suppliers tests and shall be responsible for performing all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the fluid conforms to the requirements of this

33、specification. 4.2 Classification of Tests Tests for all composition and property requirements are acceptance tests and preproduction tests and shall be performed prior to or on the initial shipment of fluid to a purchaser, on each lot, when a change in ingredients and/or processing requires reappro

34、val as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.2.1 Acceptance Tests Each lot of fluid shall be visually examined for quality (3.3) and tested for compliance to fluid composition requirements of Table 2 and property requirements of Table 4. The number of determinatio

35、ns for each requirement shall be as specified in the applicable test procedure or, if not specified therein, not less than three. 4.2.1.1 A lot shall be all fluid produced in one continuous manufacturing operation from the same batches of raw materials and presented for suppliers inspection at one t

36、ime. 4.2.1.2 When a statistical sampling plan has been agreed upon by purchaser and supplier, sampling shall be in accordance with such plan in lieu of sampling as in 4.4.1 and the report of 4.5 shall state that such plan was used. 4.2.2 Preproduction Tests As agreed upon by purchaser and supplier.

37、4.3 Shelf-Life Surveillance and Updating Inspections to be conducted for shelf-life extension are aromatic content and mercaptan content in accordance with test methods indicated in Table 2. If fluid composition requirements (Table 2) for aromatic and mercaptan content are met, the shelf life may be

38、 extended an additional 90 days. Additional 90-day shelf life extensions require verification of all fluid composition and property requirements in accordance with Tables 2 and 4. SAE INTERNATIONAL AMS2629E Page 6 of 7 4.4 Approval 4.4.1 Sample fluid shall be approved by purchaser before fluid for p

39、roduction use is supplied, unless such approval is waived by purchaser. Results of tests on production fluid shall be essentially equivalent to those on the approved sample. 4.4.2 Supplier shall use ingredients, processes, and methods of inspection on production fluids which are essentially the same

40、 as those used on the approved sample. If necessary to make any change in ingredients or processing, in type of equipment for processing, or in manufacturing procedures, supplier shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sam

41、ple fluid. Production fluid made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Reports The fluid supplier shall furnish with each shipment a report showing the results of tests to determine conformance to the fluid composition and property requirements. This repor

42、t shall include the purchase order number, lot number, AMS2629E, suppliers material identification, and quantity. 4.5.1 A safety data sheet shall be supplied to each purchaser prior to, or concurrent with, the report of preproduction test results or, if preproduction testing be waived by purchaser,

43、concurrent with the first shipment of fluid for production use. Each request for modification of fluid formulation shall be accompanied by a revised data sheet for the proposed formulation. 4.6 Resampling and Retesting If any sample used in the above tests fails to meet the specified requirements, d

44、isposition of the fluid may be based on the results of testing three additional fluid samples for each original nonconforming sample. Failure of any retest sample to meet the specified requirements shall be cause for rejection of the fluid represented. Results of all tests shall be reported. 5. PREP
