ASTM E324-99 - 10.9.1999
 
1. Scope

1.1 This test method covers the determination, by a capillary tube method, of the initial melting point and the final melting point, which define the melting range, of samples of organic chemicals whose melting points without decomposition fall between 30 and 250°C.

1.2 This test method is applicable only to crystalline materials that are sufficiently stable in storage to meet the requirements of a satisfactory standard sample as defined in Section 6.

1.3 This test method is not directly applicable to opaque materials or to noncrystalline materials such as waxes, fats, and fatty acids.

1.4 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.
