Standard Guide for Testing Epoxy Resins
SIGNIFICANCE AND USE
This guide directs the user to test methods that determine properties generally accepted as standard test items for classification of epoxy resins.
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.
