This test method covers the qualitative determination of the polyols in alkyd resins, including resin-modified alkyds. It may be used for analyzing polyesters, but additional peaks may appear from monomers such as styrene.

Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in February 2006 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Область применения

1.1 This test method covers the qualitative determination of the polyols in alkyd resins, including resin-modified alkyds. It may be used for analyzing polyesters, but additional peaks may appear from monomers such as styrene.

1.2 The constituents of three resin samples have been correctly identified in collaborative work by five laboratories. Quantities as low as 1%, obtained by blending samples of known composition, were readily detected.

1.3 This standard does not purport to address the safety problems 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.> For a specific hazard statement, see Section 7.
