ASTM D624-00(2012)
Standard Test Method for Tear Strength of Conventional Vulcanized Rubber and Thermoplastic
Elastomers
1.1 These practices cover the evaluation of all plastic materials including cast,
hot-molded, cold-molded, laminated resinous products, and sheet materials for resistance
to chemical reagents. These practices include provisions for reporting changes in
weight, dimensions, appearance, and strength properties. Standard reagents are specified
to establish results on a comparable basis. Provisions are made for various exposure
times, stress conditions, and exposure to reagents at elevated temperatures. The
type of conditioning (immersion or wet patch) depends upon the end-use of the material.
If used as a container or transfer line, immerse the specimens. If the material will
only see short exposures or will be used in proximity and reagent will splash or
spill on the material, use the wet patch method of applying reagent.
1.2 The effect of chemical reagents on other properties shall be determined by making
measurements on standard specimens for such tests before and after immersion or stress,
or both, if so tested.
1.3 The values stated in SI units are to be regarded as standard. The values given
in parentheses are for information only.
1.4 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. Specific hazards statements are given in
Section 7.
NOTE 1 This standard and ISO 22088 Part 3 address the same subject matter, but differ
in technical content (and the results cannot be directly compared between the two
test methods).
