scope:

This standard describes a method of laboratory testing to measure the performance of general ventilation air-cleaning devices.

The method of testing measures the performance of aircleaning devices in removing particles of specific diameters as the devices become loaded by standardized loading dust fed at intervals to simulate accumulation of particles during service life. The standard defines procedures for generating the aerosols required for conducting the test. The standard also provides a method for counting airborne particles of 0.30 to 10 μm in diameter upstream and downstream of the air-cleaning device in order to calculate removal efficiency by particle size.

This standard also establishes performance specifications for the equipment required to conduct the tests, defines methods of calculating and reporting the results obtained from the test data, and establishes a minimum efficiency reporting system that can be applied to air-cleaning devices covered by this standard.

PURPOSE

This standard establishes a test procedure for evaluating the performance of air-cleaning devices as a function of particle size.
