4.1 In some uses of petroleum wax, such as food packaging, odor intensity of the wax is an important property. For example, some description of limits on wax odor often appears in specifications for petroleum wax. The method given here provides a basis for agreement between laboratories on the odor intensity of wax using a numerical scale rather than descriptive terms. While the method is primarily intended for rating odor intensity, results can be influenced by odor type.

1.1 This test method covers a procedure for rating the odor intensity of waxes derived from petroleum.

1.2 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.

1.3 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.
