34、s and the fabric to fabric/bonds at one end of each specimen by hand. Insert the loosened ends of each specimen 1 in (25 mm) in the jaws of the mechanical tester.

36、 exhibit an original peel adhesion of 100 oz (27.8 N) min and an aged peel adhesion of 80 oz (22.3 N) min. Test Method: Separate various portions of the applied design by hand without the use of a solvent. Position the separated design section in the upper jaw, and the convertible top section in the
37、 lower jaw of a mechanical tester. Pull at a 180 angle at the rate of 12 in (305 mm)/min. Aged peel adhesion values shall be determined on preconditioned samples subjected to a 500 h weatherometer exposure period (FLTM BO 101-01) in accordance with the test procedure described above.
