(Test Method)Standard Test Method for Strength Properties of Adhesives in Plywood Type Construction in Shear by Tension Loading
Standard Test Method for Strength Properties of Adhesives in Plywood Type Construction in Shear by Tension Loading
SIGNIFICANCE AND USE
4.1 The way adhesives are used in plywood makes shear strength an important performance criteria.
4.2 Shear strength measured by this test is suitable for use in adhesive development, manufacturing quality control, and in materials performance specifications.
SCOPE
1.1 This test method covers the determination of the comparative shear strengths of adhesives in plywood-type construction, when tested on a standard specimen and under specified conditions of preparation, conditioning, and testing. This test method is intended to be applied only to adhesives used in bonding wood to wood.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
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.

INTRODUCTION
The accuracy of the results of strength tests of adhesive bonds will depend on the conditions under
which the bonding process is carried out. Unless otherwise agreed upon between the manufacturer and
the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive. In order
to ensure that complete information is available to the individual conducting the tests, the
manufacturer of the adhesive shall furnish numerical values and other specific information for each of
the following variables:
(1) The moisture content of the wood at the time of bonding.
(2) Complete mixing directions for the adhesive.
(3) Conditions for application of the adhesive including the rate of spread or thickness of film,
number of coats to be applied, whether more than one coat is required.
(4) Assembly conditions before application of pressure, including the room temperature, length of
time, and whether open or closed assembly is to be used.
(5) Curing conditions, including the amount of pressure to be applied, the length of time under
pressure and the temperature of the assembly when under pressure. It should be stated whether this
temperature is that of the bond line, or of the atmosphere at which the assembly is to be maintained.
(6) Conditioning procedure before testing, unless a standard procedure is specified, including the
length of time, temperature, and relative humidity.
A range for any variable or combination of variables is permitted provided any arbitrarily chosen
value within the range or combinations specified is acceptable to both the manufacturer and the
purchaser of the adhesives.

by the test operator that any arbitrarily chosen value within such a range or any combination of such
values for several variables will be acceptable to both the manufacturer and the purchaser of the
adhesive.
