Subcommittee D01.35 on Solvents, Plasticizers and Chemical Intermediates recently conducted an interlaboratory study that determined the precision and relative bias of automatic versus manual procedure for ASTM D 1078, Standard Test Method for Distillation Range of Volatile Organic Liquids, published in 1999.

The subcommittee, which operates within Committee D01 on Paint and Related Coatings, Materials, and Applications, will revise the standard to incorporate the new precision statement. The study indicates equivalent results for automatic relative to manual instruments, thus confirming acceptable use of both procedures, according to Senior Chemist R.G. Montemayor, Ph.D., Imperial Oil Ltd., Sarnia, Ontario, Canada, the subcommittee chairman.

For further technical information, contact R.G. Montemayor, Ph.D., Products and Chemicals Division, Imperial Oil Ltd., Sarnia, Ontario, Canada (fax: 519/339-5945). Committee D01 meets June 10-13 in Pittsburgh, Pa., in conjunction with ASTM Committee G03 on Weathering and Durability.
