ASTM E1868-02

Standard Test Method for Loss-On-Drying by Thermogravimetry

SCOPE
1.1 This test method covers a procedure for determining the amount of volatile matter of any kind that is driven off from a test specimen under a specific set of temperature and time conditions. This test method determines only the mass of material lost, not its identity.
1.2 This test method is applicable to a wide variety of solid or liquid materials, mixtures or blends where the major component is stable at the test temperature.
1.3 The applicable temperature range for this test method is generally between ambient temperature and 1000°C.
1.4 Electronic instrumentation or automated data analysis and data reduction systems or treatments equivalent to this method may be used.
Note 1—Users are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user to determine the necessary equivalency prior to use.
1.5 SI units are the standard.
1.6 There is no ISO standard equivalent to this test method.
1.7 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 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
