(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
SIGNIFICANCE AND USE
5.1 This test method provides reasonably accurate information with regard to the ability of an adhesive to withstand shearing forces. It may also be used to determine degree of cure and the effect of environment on shear strength.
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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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
