Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of

7、 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure Preparation of Test Assemblies: 1. Condition coupons and test material for 24 h at 23 +/- 2 C and 50 +/- 5 % relative humidity. 2. Clean the

8、 test coupons with petroleum naphtha or equivalent solvent. (Prepare a minimum of 3 assemblies (2 coupons per assembly) for each test condition and exposure). 3. Apply a uniform film coating of the oil or drawing compound onto the test coupon (specified by the Engineering Material Specification) usi

Insert wire spacers into the test material to maintain material bondline thicknesses that are specified to be

10、 less than 1.5 mm. . Use a template as a spacer of the appropriate thickness for material bondline thicknesses that are specified to be thicker than 1.5 mm. 5. Carefully position the end of another prepared coupon over the parallel to the coupon with the applied material to form a 650 mm2 overlap bo

Remove excess material that was squeezed out from coupon surface after assembly. 8. To assist in holding the coupon assembly together, attach two

12、 bulldog clips at the bonded area (as shown in Figure 1). 9. Condition coupon assemblies prepared with heat cure test materials for 1 h minimum at 23 +/- 2 C and 50 +/- 5 % relative humidity and then cure the assemblies as specified in the Engineering Material Specification.
