7.1.5 Cure the specimens in accordance with the manufac-
turer’s instructions.
7.1.5.1 For primed or activated surfaces, when specified or
recommended, use the manufacturer’s primer. Apply the
primer and adhesive according to the manufacturer’s instruc-
tions. Assemble and cure the specimens for a time and
temperature in accordance with the manufacturer’s recommen-
dation.
8. Procedure
8.1 After allowing for cure and any planned environmental
conditioning, determine the static shear strength as follows:
8.1.1 Place the pin and collar assembly on the universal test
machine as shown in Fig. 3. Load the specimen smoothly at
about 500 lb/s (2200 N/s) using a free crosshead speed of 0.05
in./min (1.3 mm/min). Record the maximum load in pounds
(Newtons). Calculate the static shear strength by dividing the
