20、equired tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the sponge conforms to the requirements of this specification.4.2 Classification of Tests: Tests for all technical requirements are acceptance tests and preproduction tests a
21、nd shall be performed prior to or on the initial shipment of sponge to a purchaser, on each lot, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required.4.2.1 For direct U.S. Military procurement, substantiating tes

25、ot 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.4.3.1.1 A lot shall be all sponge produced from the same batch of compound processed in one continuous producti
26、on run and presented for vendors inspection at one time. A lot shall not exceed 500 pounds (227kg) and may be packaged in smaller quantities and delivered under the basic lot approval provided lot identification is maintained.4.3.1.2 A batch shall be the quantity of compound run through a mill or mi
27、xer at one time.4.3.1.3 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 4.3.1 and the report of 4.5 shall state that such plan was used.4.3.2 For Preproduction Tests: As agreed upon by purchaser a
28、nd vendor.4.4 Approval: 4.4.1 Sample sponge shall be approved by purchaser before sponge for production use is supplied, unless such approval be waived by purchaser. Results of tests on production sponge shall be essentially equivalent to those on the approved sample.4.4.2 Vendor shall use ingredien
29、ts, manufacturing procedures, processes, and methods of inspection on production sponge which are essentially the same as those used on the approved sample sponge. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedures, vendor shall submit
30、 for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample sponge. Production sponge made by the revised procedure shall not be shipped prior to receipt of reapproval.4.5 Reports: The vendor of sponge shall furnish with each shipment a report sho
31、wing the results of tests to determine conformance to the technical requirements. This report shall include the purchase order number, vendors compound number, lot number, AMS 3196F, form or part number, and quantity.4.6 Resampling and Retesting: If any specimen used in the above tests fails to meet
32、 the specified requirements, disposition of the sponge may be based on the results of testing three additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the sponge represented. Results of all
33、tests shall be reported.5.
