Description (English):

ISO 12500-1:2007 specifies the test layout and test procedures required for testing coalescing filters used in compressed-air systems to determine their effectiveness in removing oil aerosols. ISO 12500-1:2007 provides the means to indicate performance characteristics of the pressure drop and the capability of removing oil aerosols. ISO 12500-1:2007 defines one method of presenting filter performance as outlet oil aerosol concentration stated in milligrams per cubic metre from results obtained under standard rating parameters.

Abstract

Overview

ISO 12500-1:2007 - "Filters for compressed air - Test methods - Part 1: Oil aerosols" specifies the test layout and procedures for evaluating coalescing filters used in compressed-air systems. The standard defines how to measure a filter’s ability to remove oil aerosols and the associated pressure drop, and presents one method of reporting filter performance as outlet oil aerosol concentration (mg/m³) under defined rating parameters.

Key topics and technical requirements

Test layout and equipment: Typical test rig arrangement (air supply, aerosol generator, flow control, sensing points, filter under test) and sampling points are defined.
Standard rating parameters: Reference conditions include inlet temperature (~20 °C), test pressure (commonly 700 kPa / 7 bar(e)), rated flow (100% of manufacturer’s rated flow) and inlet oil-aerosol challenge concentration (documented test values).
Aerosol challenge: Poly-disperse oil aerosol with mean particle size ~0.15–0.40 µm (by particle count). Care to ensure aerosols, not wall flow, enter the filter.
Flow and Reynolds number: Tests use the manufacturer’s maximum rated continuous flow; minimum Reynolds number in the inlet pipe shall be 4 000 to maintain turbulent flow.
Conditioning and wet pressure drop: Filters must reach equilibrium (liquid oil visible in housing and pressure-drop change
