Standards for Oil and Grease in Water Under Way; Round Robin Chemists
Sought
Interested parties are invited to meet with two new task groups
of ASTM Subcommittee D19.06 on Organics in Water on Tuesday, Jan.
16, 2001, during the meetings of ASTM Committee D19 on Water in Cocoa Beach, Fla., Jan. 14-18, 2001. Non-members
may attend. 
At the June meetings of Committee D19, it was recommended during
an Oil and Grease Workshop that the subcommittee form two new
task groups for the analysis of oil and grease:
Task Group D19.06.03.03 will develop a draft of a screening method
for oil and grease using portable infrared instruments in the
field; and Task Group D19.06.04.04 will evaluate a new solvent
that can be substituted in existing test methods to replace freon
and other environmentally unfriendly solvents. Round-robin participants
are sought for this standard.
Ikon Solvent-P, developed under contract for the Defense Department,
was first brought to our attention at the June workshop. The chemical
structure includes iodine, which is more environmentally friendly
than chlorofluorohydrocarbons, said the subcommittee chairman,
Martha Hendrick-Smith, manager, U.S. Coast Guard Marine Safety
Laboratory, Groton, Conn. We will fast-track the development
of this standard, which we hope will replace a widely used freon-based
ASTM standard, D 3921, Test Method for Oil and Grease and Petroleum Hydrocarbons in
Water. Freon cannot be legally imported and laboratories which
have limited supplies of freon would like an alternative.
The subcommittee will also be initiating round robin testing after
January 2001 for another standard test method, under development
several years, that analyzes low-level petroleum hydrocarbons
in water.
To participate in either round robin, contact Martha Hendrick-Smith, Manager, U.S. Coast Guard Marine Safety Laboratory, 1082 Shennecossett
Rd., Groton, CT 06340 (860/ 441-2777; fax: 860/441-2641). For
further Committee D19 membership or meeting details, contact Staff
Manager Bruce Noe, ASTM (610/832-9719). //
