Standard Guide for Testing Epoxy Resins

Fecha:
2017-06-19 /Active
Significance and Use:

3.1 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.
