ENGINEERING DATASETS · OPEN ACCESS
Filtration Engineering Reference Datasets
Downloadable datasets derived from ISO, ASTM, and SAE engineering standards. Available in JSON and CSV formats for use in fluid analysis software, maintenance management systems, and engineering calculations. All data is traceable to the governing standard cited for each dataset.
ISO 4406 Range Number Table
Particle count brackets for all 24 Range Numbers per ISO 4406:2021
Complete Range Number (RN) to particle count per millilitre conversion table with component-specific cleanliness targets (servo valve, piston pump, gear pump, engine bearing). Essential for interpreting oil analysis reports and setting filtration specifications.
Beta Ratio to Filtration Efficiency Conversion
ISO 16889 β_x(c) values and their equivalent single-pass efficiency percentages
Conversion table from ISO 16889:2022 Beta ratio β_x(c) to filtration efficiency percentage, including typical application specifications for servo valve circuits (β₃(c) ≥ 200), proportional valve circuits (β₆(c) ≥ 75), mobile hydraulic systems, and kidney-loop polishing filters.
ISO 8573-1 Compressed Air Purity Classes
Particle, water (dew point), and oil content limits for Classes 0–X
Complete ISO 8573-1:2010 purity class table for compressed air quality — solid particle concentration by size band, pressure dew point by class, and total oil aerosol limits. Includes typical application specifications for food, pharmaceutical, painting, instrument air, and mining pneumatic systems.
DATASET INTEGRITY
All datasets are compiled directly from the governing standard text. No extrapolation, no interpolation beyond values stated in the standard. Range boundary values are as defined in the original published standard. If a value appears to differ from another published source, verify against the primary standard document — ELIMFILTERS does not modify published standard data.
