39、ed in a continuous series of operations from the same batches of ingredients and presented for vendors inspection at one time. 4.3.1 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 rep
40、ort of 4.5 shall state that such plan was used. 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 essentially equivalent to those on the approved
41、 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 manufacturing procedures, vendor shall submit for r

Production cleaner made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Reports The vendor of cleaner shall furnish with each shipment a report showin
43、g the results of tests to determine conformance to the acceptance test requirements and stating that the cleaner conforms to the other technical requirements. This report shall include the purchase order number, lot number, AMS1523B, manufacturers identification, and quantity. 4.5.1 A material safet
44、y data sheet conforming to FED-STD-1313, or equivalent, shall be supplied to each purchaser prior to, or concurrent with, the report of preproduction tests results or, if preproduction testing be waived by purchaser, concurrent with the first shipment of cleaner for production use. Each request for
45、modification of cleaner 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, disposition of the cleaner may be based on the results of testing three addition
46、al 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 The product shall be
