5.1 The related methods of determining the melt point of petroleum wax are relatively time-consuming. This method endeavors to reduce the duration of testing significantly and at the same time maintain a reasonable precision. This method can be useful for quality control of petroleum waxes as well as research and product development work on these waxes.

5.2 For methods used for testing melt points of petroleum waxes, see Tests Method D87, D127, including Petrolatum and Test Method D938.

1.1 This test method covers a procedure for rapidly determining the solidification point of petroleum wax.

Note 1: This test method is also applicable to similar materials such as synthetic waxes but the precision may vary.

1.2 The values stated in SI units are to be regarded as the standard. .

1.2.1 Exception—The values given in parentheses are for information only

1.3 This standard does not purport to address all of the safety problems, 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.

1.4 This 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.
