QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the cleaner shall supply al
32、l 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 that the cleaner conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance
33、Tests Effect on plastics (3.2.4), 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 Corrosion of metal surfaces (3.2.1), hydrogen embrittlement (3.2.2), flash point (3.2.3), effect on painted surfaces (3.2.5), storag
34、e stability (3.2.7), emulsion 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 preproduction tests and shall be pe
35、rformed prior to or on the initial shipment of 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 Shall be in accordance with ASTM D 1568; a lot shall be all cl

SAE AMS1528D - 5 - 4.4 Approval 4.4.1 Sample cleaner shall be approved by purchaser before cleaner for production use is supplied, unless
37、 such approval be waived by purchaser. Results of tests on production cleaner shall be essentially 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
38、 the approved sample cleaner. If necessary to make any change in ingredients or in manufacturing 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 s
39、hall not be shipped prior to receipt of reapproval. 4.5 Reports The vendor 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 cleane

41、er may be based on the results of testing three additional 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
42、Packaging and Identification 5.1.1 Cleaner shall be packaged in containers of a type and size acceptable to purchaser. 5.1.2 A lot of cleaner may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained. 5.1.3 Each container of cleaner shal
