Organization: ASTM International
Publication Date: 1 October 2015
Status: active
Page Count: 2
ICS Code (Waxes, bituminous materials and other petroleum products): 75.140
significance And Use:

4.1 This test method is used to determine the property of acid functionality. Acid functionality determines the utility of the wax as well as being a significant Quality Control test.

scope:

1.1 This test method covers the determination of the acid number of synthetic waxes and natural waxes. The number is obtained by direct titration of the material and indicates the amount of free acid present.

1.2 This test method, using an ethanol-xylene mixture, is applicable to all natural waxes, including carnauba. The test method is also applicable to oxidized microcrystalline waxes, oxidized Fischer-Tropsch, oxidized polyethylene, and montan esters.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
