Standard Guide for
Testing Epoxy Resins1

This standard is issued under the fixed designation D 4142; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This guide covers methods for testing epoxy resins as
listed in Table 1. All of the methods were tested by interlaboratory participation in accordance with usual ASTM guidelines. Each method specifies a recommended amount of sample
for starting a separate analysis, but several of the procedures
can be conducted on the same starting material if so desired.
For example, viscosity, color, and density could be run on the
same specimen.

1.2 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.
