Scope:

1.1 This test method covers procedures for assessing the volatility of solids and liquids at given temperatures using thermogravimetry under prescribed experimental conditions. Results of this test method are obtained as volatility rates expressed as mass per unit time. Rates 5 g/min are achievable with this test method.

1.2 Temperatures typical for this test method are within the range from 25C to 500C. This temperature range may differ depending upon the instrumentation used.

1.3 This test method is intended to provide a value for the volatility rate of a sample using a thermogravimetric analysis measurement on a single representative specimen. It is the responsibility of the user of this test method to determine the need for and the number of repetitive measurements on fresh specimens necessary to satisfy end use requirements.

1.4 Computer- or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used.

Note 1

Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this test method to determine the necessary equivalency prior to use.

1.5 SI units are the standard.

1.6 There is no ISO method equivalent to this standard.

This 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 test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
