GSO ASTM D7371:2021 Scope
1.1 This test method covers the determination of the content
of fatty acid methyl esters (FAME) biodiesel in diesel fuel oils.
It is applicable to concentrations from 1.00 to 20 volume %
(see Note 1). This procedure is applicable only to FAME.
Biodiesel in the form of fatty acid ethyl esters (FAEE) will
cause a negative bias.
NOTE 1—Using the proper ATR sample accessory, the range maybe
expanded from 1 to 100 volume %, however precision data is not available
above 20 volume %.
1.2 The values stated in SI units of measurement are to be
regarded as the standard. The values given in parentheses are
for information only.
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.
