ASTM Committee D19 on Water seeks volunteers to develop a Standard Test Method for Oxidation-Reduction Potential of Water with a task group of Subcommittee D19.03 Sampling Water and Water-Formed Deposits, Analysis of Water for Power Generation and Process Use, On-Line Water Analysis, and Surveillance of Water.

Representatives of testing laboratories, instrumentation manufacturers, and scientists specializing in applications, or research and development, should contact the task-group chairman, Mike Dziewatkoski (see below). Task group participation will require a minimal time commitment, Dziewatkoski says. The interlaboratory group will collect data on the measurement technique to develop a precision and bias statement.

The subcommittee initiated the proposed test method to benefit specialists involved with process analytical chemistry, online water analysis, water-quality, or environmental testing.

To participate or obtain further information, contact Mike Dziewatkoski, YSI, Inc., Yellow Springs, Ohio (phone: 937/767-7241, ext. 266). Committee D19 meets June 22-26 in Louisville, Ky. For membership or meeting details, contact Len  Morrissey, manager, ASTM Technical Committee Operations (610/832-9719). //
