QUALITY A

    35、SSURANCE PROVISIONS 4.1 Responsibility for Inspection The manufacturer of the core shall supply all samples and shall be responsible for all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the core conforms to the specifi

    36、ed requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1.1), density (3.2.1), cell count (3.2.1), foil thickness (3.2.1), compressive strength (3.4.1), shear strength (3.4.2), node bond strength (3.4.3), and flexibility (3.4.4) are acceptance tests and shall be performed

    37、on each lot of foil or core as applicable. 4.2.2 Preproduction Tests All technical requirements are preproduction tests and shall be performed prior to or on the initial shipment of core by the manufacturer, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when pur

    38、chaser deems confirmatory testing to be required. SAE AMS 4177D Page 7 of 11 4.3 Sampling and Testing Shall be in accordance with the following schedule: Composition (3.1.1): Each lot of foil Density (3.2.1): Each lot of core Cell Count (3.2.1): Each lot of core Foil Thickness (3.2.1): Each lot of c

    40、 from the foil producer. 4.3.2 A lot of core shall be all product fabricated at one time to form a block of expanded core. 4.4 Approval 4.4.1 Sample core shall be approved by purchaser before core for production use is supplied, unless such approval be waived by purchaser. Results of tests on produc

    41、tion core shall be essentially equivalent to those on the approved sample. 4.4.2 Manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspection on production core which are essentially the same as those used on the approved sample. If necessary to make any change

    42、in ingredients, in type of equipment for processing, or in manufacturing procedures, manufacturer shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requested, sample core. Production core made by the revised procedure shall not be shipped prio

    43、r to receipt of reapproval. 4.5 Test Methods 4.5.1 Cell Count Shall be determined by actual count of cells per linear foot (meter) of transverse direction (See Figure 1). Make six determinations and report each value and the arithmetic mean. 4.5.2 Core Density Shall be determined by weight of a know

    44、n volume. The test specimens shall be at least 12 x 12 inches (305 x 305 mm) x core thickness. The specimen dimensions shall be measured to the nearest 0.010 inch (0.25 mm) and weighed to an accuracy of 1.0%. Calculate density using Equation 1 for each of three determinations, reporting each value a

    46、.88T x 127L x 254W mm) core slice shall be tested in a suitable core tension fixture by mounting, without causing cell distortion, at opposite ends of the “W“ dimension (See Figure 1) with round pins. Pins shall be as large as cell size permits and engage all cells of a continuous row. Opposite pins

    47、 shall be in mirror image alignment at a distance as near to 8 inches (203 mm) as this mounting method permits. The fixture shall be slotted to allow horizontal pin movement. A steady loading rate of 1.00 inch 0.05 (25.4 mm 1.3) per minute shall be maintained. 4.5.4 Flexibility Test A 10-inch (254-m
