This test method determines the initial melting point and melting range of waxes. The data obtained are important in the application of waxes in one-time carbon inks.

1.1 This test method covers the determination of the initial and final melting points and recovery point of waxes using a hot stage and microscope.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 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. See Section 8 for a specific precautionary statement.
