Title
Standard Test Method for dimer/trimer of chlorotrifluoroethylene (S-316) Recoverable Oil and Grease and Nonpolar Material by Infrared Determination
ASTM International
Publication Date:
Jun 1, 2004
Scope:
This test method covers the determination of oil and grease and
nonpolar material in water and wastewater by an infrared (IR)
determination of dimer/trimer of chlorotrifluoroethylene (S-316)
extractable substances from an acidified sample. Included in this
estimation of oil and grease are any other compounds soluble in the
solvent.
The method is applicable to measurement of the light fuel
although loss of some light ends during extraction can be
expected.
This method defines oil and grease in water and wastewater as
that which is extractable in the test method and measured by IR
absorption at 2930 cm-1 or 3.4 microns. Similarly, this
test method defines nonpolar material in water and wastewater as
that oil and grease which is not adsorbed by silica gel in the test
method and measured by IR absorption at 2930 cm-1.
This method covers the range of 5 to 100 mg/L and may be
extended to a lower or higher level by extraction of a larger or
smaller sample volume collected separately.
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 (D 3856 Guide for Good
Laboratory Practices2) the applicability of
regulatory limitations prior to use.

ASTM Committee D19 on Water and is the direct responsibility of
Subcommittee D19.06 on Methods for Analysis for Organic Substances
in Water. Current edition approved June 1, 2004. Published July
