ASTM D1876-08

Standard Test Method for Peel Resistance of Adhesives (T-Peel Test)

ABSTRACT
This test method is primarily intended for determining the relative peel resistance of adhesive bonds between flexible adherends by means of a T-type specimen using a tension testing machine. The bent, unbonded ends of the test specimen shall be clamped in the test grips of the tension testing machine and a load of a constant head speed shall be applied. An autographic recording of the load versus the head movement or load versus distance peeled shall be made. The peel resistance over a specified length of the bond line after the initial peak shall be determined.
SCOPE
1.1 This test method is primarily intended for determining the relative peel resistance of adhesive bonds between flexible adherends by means of a T-type specimen.
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 and health practices and determine the applicability of regulatory limitations prior to use.

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 by 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) Procedure for preparation of the surfaces prior to application of the adhesive, the cleaning and
drying of metal surfaces, and special surface treatments such as sanding, which are not specifically
limited by the pertinent test method.
(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 to be applied to one or both surfaces, and the conditions of
drying where 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 glue 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.
