The ASTM D02.CS96 Subcommittee for In-Service Lubricant Testing brings together people from many parts of the industry. Its members come from oil analysis labs, instrument makers, service providers, OEMs and end users. Together, they advance standards for in-service lubricant testing and condition monitoring.
These standards matter because they keep oil analysis accurate, consistent and practical. As a result, labs and end users can trust the numbers they use to judge oil health and run their programs.

Who Can Join
Anyone who wants to help shape these standards can join. In return, members get an early look at new tools and test methods. They also work with industry experts and contribute to precision and validation studies. Above all, they help keep ASTM methods relevant and technically sound.
The CS96 Subcommittee meets twice a year, in June and December. These meetings take place during ASTM D02 Petroleum Products, Liquid Fuels, and Lubricants Committee Week.
Where CS96 Fits Within ASTM D02
For context, the ASTM D02 Committee writes and maintains more than 800 standards. People around the world use them for petroleum products, liquid fuels and lubricants. Within D02, the CS96 Subcommittee manages 45 standards. Each one is reviewed every five years for technical accuracy.
Highlights from the June 2026 Meeting
In June 2026, the ASTM D02 Committee Week took place in Chicago, IL. There, CS96 members took part in technical discussions and reviewed standards. They also stressed the need to keep test methods in step with what the industry needs today.
The group now has three main priorities: modernizing existing standards, developing methods for emerging technologies, and strengthening the precision of existing methods.
Three Priorities for CS96
Modernizing Existing Standards
First, CS96 is reviewing and updating standards for many core oil analysis technologies. These include FTIR, wear debris monitoring and particle quantification (PQ). The list also covers particle counting, viscosity measurement, grease analysis and moisture analysis.
Developing New Methods for Emerging Technologies
Next, CS96 is looking at standards for newer tools. These include online sensors, portable field-testing tools and in-service grease analysis. In addition, the Subcommittee is exploring standard guides. Such guides would help end users pick the right oil tests for their machines.
Strengthening the Precision of Standards
Finally, several groups are running interlaboratory studies and statistical validation work. The goal is results that agree more closely from one lab to the next. Key topics here include particle counting, FTIR, moisture analysis, in-service viscosity testing and particle quantification (PQ).
Above all, broader industry participation keeps these standards relevant, practical and technically accurate.
What’s Next: Get Involved
The Subcommittee welcomes new members. In particular, it is looking for people with expertise or interest in:
- FTIR applications in oil analysis
- Particle quantification (PQ) and wear debris analysis
- Particle counting
- Viscosity measurement technologies
- Online (sensor) and portable condition monitoring tools
- In-service grease analysis
- Statistical analysis of oil condition monitoring data
- New or emerging trends in oil condition monitoring technology
There are many ways to take part. For example, you can review existing standards or join round-robin studies. You can also share technical knowledge, introduce new technology or simply stay current with the industry. Either way, CS96 membership is a practical way to get involved.
The Next Meeting: Orlando, December 2026
The next ASTM D02 meeting for the CS96 Subcommittee is December 6–10, 2026, at the Renaissance Orlando at SeaWorld, 6677 Sea Harbor Dr, Orlando, Florida. For more information, visit astm.org or contact Subcommittee Chair Lisa Williams at lisa.williams@ametek.com.
