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.

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.
