    Withdrawn Rationale:

    This test method covers a quality control test for nonvolatile content of latex vehicles. The specified time-temperature conditions (180C, 20 min) were selected to allow test completion in 1 h or less. For latex vehicles used in certain air-dry or low-temperature bake coatings, as well as for those that contain temperature-sensitive materials, the use of a lower temperature and other bake time will more accurately reflect the effective nonvolatile content). Alternative time-temperature conditions should be agreed upon between the producer and user.

    Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in March 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.

    1. Scope

    1.1 This test method covers a quality control test for nonvolatile content of latex vehicles. The specified time-temperature conditions (180°C, 20 min) were selected to allow test completion in 1 h or less. For latex vehicles used in certain air-dry or low-temperature bake coatings, as well as for those that contain temperature-sensitive materials, the use of a lower temperature and other bake time will more accurately reflect the effective nonvolatile content (Note 1). Alternative time-temperature conditions should be agreed upon between the producer and user.

    Note 1-The test conditions of Test Method D2369 (110°C, 60 min) have been found suitable for use with many latex vehicles.

    1.2 This test method is not intended to be employed for determining the volatile organic content (VOC) of formulated coatings.

    1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
