31、ect on painted surfaces (3.2.5), effect on unpainted surfaces (3.2.6), and quality (3.3) are acceptance tests and shall be performed on each lot. 4.2.2 Periodic Tests Sandwich corrosion (3.2.1.1), low-embrittling cadmium plate (3.2.1.3), hydrogen embrittlement (3.2.2), flash point (3.2.3), effect on
32、 plastics (3.2.4), abrasive effects (3.2.7), storage stability (3.2.8), and performance (3.2.9) are periodic tests and shall be performed at a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.2.3 Preproduction Tests All technical requirements are preproductio
33、n tests and shall be performed prior to or on the initial shipment of the cleaner to a purchaser, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.3 Sampling and Testing Sufficient cleaner shall be taken a
34、t random from each lot 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. A lot shall be all cleaner produced in a single production run from the same batches of ra
35、w materials under the same fixed conditions and presented for vendors inspection at one time. 4.4 Approval 4.4.1 Sample cleaner shall be approved by purchaser before cleaner for production use is supplied, unless such approval be waived by purchaser. Results of tests on production cleaner shall be e
36、ssentially equivalent to those on the approved sample. 4.4.2 Vendor shall use ingredients, manufacturing procedures, and methods of inspection on production cleaner which are essentially the same as those used on the approved sample cleaner. If necessary to make any change in ingredients or in manuf
37、acturing procedures, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample cleaner. Production cleaner made by the revised procedure shall not be shipped prior to receipt of reapproval. SAE AMS1531D - 5 - 4.5 Reports The v
38、endor of cleaner shall furnish with each shipment a report showing the results of tests to determine conformance to the acceptance test requirements and, when performed, to the periodic test requirements and stating that the cleaner conforms to the other technical requirements. This report shall inc
39、lude the purchase order number, AMS1531D, manufacturers identification, formula number, lot number, and quantity. 4.6 Resampling and Retesting If any sample used in the above tests fails to meet the specified requirements, disposition of the cleaner may be based on the results of testing three addit
40、ional samples for each original nonconforming sample. Failure of any retest sample to meet the specified requirements shall be cause for rejection of the cleaner represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Packaging and Identification 5.1.1 Cleaner shall be p
