Organization: ASTM International
Publication Date: 1 January 2012
Status: inactive
Page Count: 7
ICS Code (Liquid fuels): 75.160.20
significance And Use:

Petroleum-based diesel may be blended with biodiesel. High levels of free glycerin in biodiesel can cause injector deposits ("gel effect"), as well as clogging fuel systems. High levels of... View More

scope:

1.1 This test method covers and describes an anion exchange chromatography procedure for determining free and total glycerin content of biodiesel (B100) and blends (B0 to B20) with diesel fuel oils defined by Specification D975 Grades 1-D, 2-D, and low sulfur 1-D and 2-D and Specification D6751 (for B100 feedstocks). It is intended for the analysis of biodiesel and blend samples containing between 0.5 to 50 mg/kg glycerin.

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