Organization: ASTM
Publication Date: 10 March 2003
Status: inactive
Page Count: 6
ICS Code (Heat. Calorimetry): 17.200.10
scope:

This method describes the determination of purity of materials greater than 98.5 mole percent purity using differential scanning calorimetry and the van't Hoff equation.

This test method is applicable to thermally stable compounds with well-defined melting temperatures.

Determination of purity by this test method is only applicable when the impurity dissolves in the melt and is insoluble in the crystal.

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

NOTE 1 - Since all data treatments are not equivalent, it is the responsibility of the user to verify equivalency prior to use.

SI values are the 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 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

There is no ISO method equivalent to this method.
