1.1These test methods cover procedures for assessing the volatility of solids and liquids at given temperatures using thermogravimetry under prescribed experimental conditions. Results of these test methods are obtained as volatility rates expressed as mass per unit time. Rates ≥5 μg/min are achievable with these test methods.

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

1.3These test methods are 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 these test methods to determine the need for and the number of repetitive measurements on fresh specimens necessary to satisfy end use requirements.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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 these test methods to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.6This 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.
