Petroleum Subcommittee at Work on Several New Proposed Standards

Since its formation in 2001, Subcommittee D02.96 on In-Service Lubricant Testing and Condition Monitoring Services, part of ASTM International Committee D02 on Petroleum Products and Lubricants, has made much progress in managing activities associated with the evaluation of in-service lubricants. The subcommittee is currently working on the following initiatives:

• A standard test method has been drafted to determine kinematic viscosity using Houillon type viscometers and an interlaboratory study is under way to determine the precision of the test method. These viscometers, because of their speed and small sample size requirement, are often employed in the used oil industry. The results obtained in this study will be compared to results obtained by the standard D 445, Test Method for Kinematic Viscosity of Transparent and Opaque Liquids and the Calculation of Dynamic Viscosity, to determine whether a bias exists between the two methods. Over 20 laboratories have offered to participate.

• A standard test method for determining oxidation of used oils by Fourier transform infrared will be balloted along with a precision statement. This peak area increase method was developed by the Coordinating European Council for monitoring used oil from a laboratory oxidation test. This method is currently used at the request of European original equipment manufacturers for oxidation monitoring in bench and field vehicle tests.

• A new particle contamination section will begin meeting regularly at the D02 meetings. They plan to invite particle count equipment vendors to the December meeting in an effort to develop a particle contamination guide.

• A new machine-generated debris section will begin meeting regularly, starting in December.

• The subcommittee is following the efforts of Subcommittee 2 on the development of a new tester for the determination of water in petroleum products. This new tester uses no hazardous solvents and is viable for the testing of used oils.

Participation is invited, especially from representatives of the oil condition monitoring industry and testers familiar with the evaluation of in-service lubricants. Members of related ASTM committees are also welcomed.
