1.1This test method covers the determination of the softening point of certain alkali-soluble resins having uniform plastic flow characteristics as the melting point is approached.

1.2The resin manufacturer should specify whether or not this test method may be used for his product(s).

1.3This test method is not suitable for styrene-maleic anhydride resins.

Note 1:For testing rosin and other resins, see Test Method E28. For testing asphalts, tars, and pitches, see Test Method D2398.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
