Standard 52.2 Committee Looking for New Members

From eSociety, September 2019

SSPC 52.2, Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size, is interested in obtaining new members representing the user interest category. 

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

The standard’s scope allows the following:

  • 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 air cleaning devices in removing particles of specific dust fed at intervals to simulate accumulation of particles diameters as the devices become loaded by standardized loading 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 0.3 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 which can be applied to air cleaning devices covered by this standard.
