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.
