(Test Method)Standard Test Method for Shear Strength of Adhesives Using Pin-and-Collar Specimen
Standard Test Method for Shear Strength of Adhesives Using Pin-and-Collar Specimen
SCOPE
1.1 This test method covers the determination of the shear strength of curing liquid adhesives used for retaining cylindrical assemblies or for locking and sealing threaded fasteners.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

the manufacturer of the adhesive shall furnish numerical values
and other specific information for each of the following
variables:

and length of time.

the length of time, temperature, and relative humidity.
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
breakaway load by the bond area as follows:
