Particle Count

Comprehensive contamination control.

Our full-service particle count analysis is essential for close tolerance turbine and hydraulic systems. It meets even the most stringent standards for monitoring particle contamination in sophisticated industrial equipment by OEMs such as General Electric, Bosch, Parker and Westinghouse. Bottom line? If you operate systems critical to production, power generation or process control, then your predictive maintenance program should include Bureau Veritas’s ISO-3 particle count analysis. It is particularly applicable for:

  • Factory production machinery, including robotics
  • Gas and steam turbines
  • Bench test equipment
  • Steering systems, winches, lift controls
  • Hydrostatic transmissions in sophisticated off-highway construction and mining equipment.

Bureau Veritas’s laboratory analysis and data reporting procedures meet all of the newly expanded ISO and NAS requirements, although we still provide particle counts based on older standards for customers with special needs for legacy testing.

ISO-3 Particle Count Analysis

Bureau Veritas includes particle count measurements and evaluations for six (6) different micron ranges, including particulates sized at or below 4µm. Filter manufacturers, OEMs and fluid analysis customers are recognizing the vital importance of particle measurements in this smaller range. We refer to this 6-range reporting as ISO-3. Analyzing fluid samples for the most minute contaminants provides customers with a third ISO Cleanliness Code instead of the older 2-code reporting. The importance of this information cannot be underestimated, since particles smaller than 4µm can accumulate as silt within systems. When contamination particles are this fine, they can clog and erode close-tolerance high-pressure components, leading to rapid fluid degradation and eventual control valve seizures.
