scope:

This standard describes a method of laboratory testing to measure the performance of UV-C lights used in general ventilating systems.

The method of test measures the performance of UV-C lights to inactivate selected indicator microorganisms in the airstream. The standard defines procedures for generating the bioaerosols required for conducting the test. It also provides a method for counting the airborne bioaerosols upstream and downstream of the UV-C light in order to calculate inactivation efficiency for each microorganism.

This standard also establishes performance specifications for the equipment required to conduct the tests, defines methods of calculating and reporting results obtained from the test data, and establishes a reporting system to be applied to UV-C lights covered herein.

PURPOSE

This standard establishes a test method for evaluating the efficacy of UV-C lights for their ability to inactivate airborne microorganisms.
