26、ot shall be all adhesive produced in a single production run from the same batches of raw materials and presented for vendors inspection at one time. An inspection lot shall not exceed 500 pounds (227 kg). 4.3.1.2 When a statistical sampling plan has been agreed upon by purchaser and vendor, samplin

27、g shall be in accordance with such plan in lieu of sampling as in 4.3.1 and the report of 4.6 shall state that such plan was used. 4.3.2 For Preproduction Tests As agreed upon by purchaser and vendor. 4.4 Approval 4.4.1 Sample adhesive shall be approved by purchaser before adhesive for production us

28、e is supplied, unless such approval be waived by purchaser. Results of tests on production adhesive shall be essentially equivalent to those on the approved sample. 4.4.2 Vendor shall use ingredients, manufacturing procedures, processes, and methods of inspection on production adhesive which are ess

29、entially the same as those used on the approved sample adhesive. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedures, vendor shall submit for reapproval a statement of the proposed changes in ingredients and/or processing and, when requ

30、ested, sample adhesive. Production adhesive made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Test Methods 4.5.1 Tensile Shear Shall be determined in accordance with ASTM D 1002 with the following modifications. Individual test pieces shall be made of AMS5044 ste

31、el, or equivalent, nominally 1/8 x 1 x 5 inches (3.2 x 25 x 127 mm). Tensile holding fixture shall allow sufficient offset to account for the metal thickness, and through-pin holding arrangement shall be allowable when 1/8 inch (3.2 mm) thick test pieces are used. The test piece width shall be 1 inc

32、h 0.1 (25 mm 3) and the overlap area approximately 0.5 square inch (323 mm2). Bonding fixtures used shall give identical pressure on the adhesive joint from batch to batch. Bonding surface shall be freshly sandblasted to obtain a uniformly roughened surface and shall be thoroughly washed with a suit

33、able solvent. 4.5.2 Thermal Cycling Samples shall be subjected to 10 thermal cycles in air as follows and tested at room temperature. One cycle shall consist of 30 minutes 5 at 67 F 2 (55 C 1), 30 minutes 5 at 75 F 2 (24 C 1), 30 minutes 5 at 158 F 2 (70 C 1), and 30 minutes 5 at 75 F 2 (24 C 1). Th

34、e cycle may be extended during any 75 F (24 C) conditioning period. 4.5.3 Thermal Aging Samples shall be maintained at 185 F 2 (85 C 1) in a circulating-air oven for 200 hours 12, removed from the oven, and allowed to stabilize at test temperature for not less than two hours before testing.

36、ared, standard glass microscope slide with a uniform, bubble-free film of adhesive 0.005 to 0.020 inch (0.13 to 0.51 mm) thick. Thin sections on corners are acceptable. Samples shall be cured according to manufacturers recommendations, weighed to 0.0001 gram, and the adhesive film weight calculated.

37、 Five samples shall be subjected to each test fluid for 96 hours 1 at 212 F 2 (100 C 1). Two samples shall be aged for 96 hours 1 at 212 F 2 (100 C 1) in a circulating-air oven. Thermal aged samples shall be cooled, allowed to stabilize at 75 F 2 (24 C 1) in a desiccator, and weighed. Samples subjec

38、ted to Ref. Fuel B shall be cooled to 75 F 2 (24 C 1) in the fuel, removed from the fuel, wiped dry, and weighed immediately. Samples subjected to Service Fluid No. 1 and Oil No. 3 shall be cooled to 75 F 2 (24 C 1), washed free of excess material with a suitable solvent, allowed to stabilize to con

39、stant weight, and weighed immediately. The initial and final average weights of samples exposed to each fluid and to hot air shall be determined and the difference expressed as percent weight change. Results shall be recorded as the difference between the percent weight change of the air aged sample

40、s and the fluid aged samples. 4.6 Reports The vendor of adhesive shall furnish with each shipment a report showing the results of tests to determine conformance to the acceptance test requirements and stating that the adhesive conforms to the other technical requirements. This report shall include t

41、he purchase order number, lot number, AMS3690C, vendors material designation, and quantity. 4.6.1 A material safety data sheet conforming to AMS2825, or equivalent, shall be supplied to each purchaser prior to, or concurrent with, the report of preproduction test results or, if preproduction testing

42、 be waived by purchaser, concurrent with the first shipment of adhesive for production use. Each request for modification of adhesive formulation shall be accompanied by a revised data sheet for the proposed formulation. 4.7 Resampling and Retesting If any specimen used in the above tests fails to m

43、eet the specified requirements, disposition of the adhesive 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 adhesive represented. Results

44、of all tests shall be reported. 5.
