ASTM D4758-92(1998) PDF

Scope: 1.1 This test method covers a quality control test for nonvolatile content of latex vehicles. The specified timetemperature 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 timetemperature conditions should be agreed upon between the producer and user. NOTE 1—The test conditions of Test Method D 2369 (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 concerns, 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.
