QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection Th

25、e vendor of film shall supply all 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 film conforms to specified requirements. 4.2 Classificati

26、on of Tests 4.2.1 Acceptance Tests Dielectric breakdown voltage (3.2.5), quality (3.3), and tolerances (3.4) are acceptance tests and shall be performed on each lot. 4.2.2 Preproduction Tests Tests for all technical requirements are preproduction tests and shall be performed prior to or on the initi

27、al shipment of film 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 Sufficient film shall be taken at random from each lot to perform all required tests. The number

28、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 A lot shall be all film produced in a single production run from the same batches of raw materials and presented for vendors inspection at one time.

29、A lot shall not exceed 1500 square feet (139 m2).4.4 Approval 4.4.1 Sample film shall be approved by purchaser before film for production use is supplied, unless such approval is waived by purchaser. Results of tests on production film shall be essentially equivalent to those on the approved sample.

30、 4.4.2 Vendor shall use ingredients, manufacturing procedures, processes, and methods of inspection on production film which are essentially the same as those used on the approved sample. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedu

31、res, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample film. Production film made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Test Methods Shall be in accordance with the following

32、: 4.5.1 Shrinkage Suspend freely five specimens, 10 inches (254 mm) long by width of film but not over 10 inches (254 mm) wide, measured to the nearest 0.01 inch (0.25 mm), in an oven maintained at 200 C 2 (392 F 4) for 30 minutes 2. Average 15 measurements for each direction by taking three in each

33、 direction on each specimen at room temperature before and after heating. The three measurements shall be made at the center and midway between the center and the edge along each side, respectively. Bench mark or pinpoint marking may be used for location of measurements.

34、eNo reproduction or networking permitted without license from IHS-,-,-SAE AMS3612C Page 6 of 84.5.2 High Temperature Durability Suspend 30 specimens, 5 inches (127 mm) long by width of film but not over 1 inch (25 mm) wide, in an oven maintained at 125 C 2 (257 F 4) for 30 minutes 2. Samples shall s

35、upport, at one end, a weight of 200 grams per 0.0010 inch (0.025 mm) thickness per 1.00 inch (25 mm) width. Raise the temperature to 220 C 2 (428 F 4) and maintain for 30 minutes 2. Cool to room temperature under load. Fold the sample 180 degrees in the machine direction. Crease under moderate finge

36、r pressure and unfold. Repeat test with fold and crease in the transverse direction. Film shall not crack. Film samples shall be taken from one mill roll lot number and shall be taken at random across the roll. 4.5.3 Dielectric Breakdown Voltage Shall be determined in accordance with ASTM D 149, sho

37、rt time test in air using 2 inch (51 mm) diameter electrodes except that 1/4 inch (6.4 mm) diameter electrodes may be used when narrow film is supplied. In tests of 40 specimens, there shall be not more than three failures in film 0.0030 inch (0.076 mm) and under in thickness and not more than four

38、failures in thicker film. 4.6 Reports The vendor of film shall furnish with each shipment a report showing the results of tests to determine conformance to the acceptance test requirements and stating that the film conforms to the other technical requirements. This report shall include the purchase

39、order number, lot number, AMS3612C, vendors material designation, size, and quantity. 4.7 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the film may be based on the results of testing three additional specimens for each orig

40、inal nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the film represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Packaging 5.1.1 A lot of film may be packaged in small quantities and delivered

41、 under the basic lot approval provided lot identification is maintained. 5.1.2 Packaging shall be accomplished to ensure that the film, during shipment and storage, will not be permanently distorted and will be protected against damage from exposure to weather or any other normal hazard.
