Sensory Evaluation Committee to Hold Open Discussion of European Odor-Threshold Standard in October

ASTM Committee E18 on Sensory Evaluation of Materials and Products invites sensory professionals and the environmental community to an open discussion of the draft European odor-threshold testing standard, prEN 13725, “Air Quality—Determination of odour concentration by dynamic olfactometry.” The discussion will be scheduled during Committee E18 meetings, Oct. 8-11 in Montreal at the LeCentre Sheraton. Contact ASTM manager Joe Hugo for details.

E18 member Mike McGinley, laboratory director, St. Croix Sensory, Inc., Lake Elmo, Minn., says Committee E18 predicts their current odor-threshold standard will face limited use in future environmental odor testing due to increased use of the European standard. The ASTM standard is E 679, Standard Practice for Determination of Odor and Taste Thresholds By a Forced-Choice Ascending Concentration Series Method of Limits.

“ASTM E 679 is a general standard for determination of odor and taste thresholds,” explains McGinley, who is coordinating the October meeting. “The E18 committee intends to keep this standard in its current form. However, the committee will discuss the use of prEN 13725 as a basis for the development of a new ASTM standard. The intent would be to develop a specific standard, which is comparable to the European draft standard, yet references essential elements from ASTM E 679 and other E18 ASTM documents.”

In late 2002, the European standard is slated for publication as a CEN standard, according to McGinley. “Australia and New Zealand have already adopted a standard identical to the European draft (AS/NZ 4323.3-2001) and organizations throughout Southeast Asia are also requiring the use of the European draft standard,” he says. “Furthermore, state and municipal air pollution regulators in the U.S. are already specifying the use of prEN 13725.”
