ASTM D903-98(2004)

Standard Test Method for Peel or Stripping Strength of Adhesive Bonds

ABSTRACT
This test method details the standard procedures for the determination of the comparative peel or stripping strength characteristics of adhesive bonds when tested on standard-sized specimens and under defined conditions of pretreatment, temperature, and testing machine speed. This method requires the use of a power-driven testing machine with a constant rate-of-jaw separation or of the inclination balance or pendulum type, and conditioning room or desiccator.
SCOPE
1.1 This test method covers the determination of the comparative peel or stripping characteristics of adhesive bonds when tested on standard-sized specimens and under defined conditions of pretreatment, temperature, and testing machine speed.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information 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.

7. Conditioning
7.1 Condition all specimens for 7 days by exposure to a
relative humidity of 50 6 2 % at 23 6 1°C (73.46 2°F) or
until equilibrium is reached, except where the adhesive manu-
facturer may specify such an aging period to be unnecessary or
a shorter period to be adequate.
7.2 Special conditioning procedures may be used by agree-
ment between the purchaser and the manufacturer.
8. Procedure
8.1 Conduct the test as soon as possible after removing the
test specimens from the conditioning atmosphere and prefer-
ably under the same conditions.
