These shall constitute the approved procedures and shall be used for manufactu

36、ring production of parts. If necessary to make any changes in the parameters for process control factors, manufacturer shall submit for reapproval a statement of the proposed changes in ingredients, and/or processing. Products manufactured using a revised procedure shall be shipped prior to reapprov

37、al in writing. Manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspection, which are essentially the same as those used on the approved sample. 4.4.1.1 Control factors for producing products include but are not limited to, the following: Compound ingredients a

38、nd proportions thereof within established limits Sequence of mixing compound ingredients Type of mixing equipment Method and equipment for preparing preforms Basic molding procedure (compression, transfer, injection) Curing time and pressure; variations of +/- 10% are permissible Finishing methods M
