This protocol has been developed to present a consistent methodology for the determination and benchmarking of UV lamp output from monochromatic (254 nm) lamps operated by a corresponding power supply (ballast). The protocol can be used for testing and comparing different lamp and ballast combinations, to compare test results from different laboratories and to compare operation under different ambient conditions. The protocol is not intended for general manufacturing quality control or quality assurance testing, or as a replacement for biodosimetry for determining the dose in UV water treatment systems. The protocol should be conducted by someone who is a UV expert and preferably by a third-party independent contractor.
