ASHRAE Standard 185.1 establishes a test method to evaluate UV-C lamps for their ability to inactivate airborne ASHRAE Standard 185.1 establishes atest method to evaluate UV-C lamps for their ability to inactivate airbornemicroorganisms. It defines procedures for generating test bioaerosols and forsampling upstream and downstream of the UV-C lamp.In addition, the standard establishesperformance specifications for test equipment, quality assurance standards, andmethods of calculating and reporting results from the test data.This method of test may also be usedto test air-cleaning devices that do not use ultraviolet technology if thedevice being tested can be installed in the testing duct system as described.Test reports should note that results were from a modified test and include thespecific device tested and modifications made to the method.
