8 | 1 Scope This document describes exposures of materials and components to UV-C radiation during ultraviolet germicidal irradiation (UVGI) treatments or other processes that require UV-C exposure and tests to simulate those environments. Severities rep… 2 Normative references 3 Terms and definitions |
9 | 4 UV-C field exposures 4.1 Overview 4.2 Exposures to UV-C irradiation |
10 | 4.3 Temperature 4.4 Humidity 5 Test chamber for UV-C exposures 5.1 Source of UV-C 5.2 General 5.3 Irradiance monitoring and control 5.3.1 Common sources of UV-C measurement error 5.3.2 Spectral mismatch errors |
11 | 5.3.3 Deviation from true cosine response 5.4 Temperature 6 Test procedures 6.1 Specimens 6.2 General 6.3 Test Conditions Table 2 describes test conditions representing a range of exposure severities. Each test duration represents the nominal UV-C dose during one year of service life, with a minimum total exposure. Irradiance levels in the table are intended to balance r… |
12 | NOTE Alternating periods of darkness can produce a different result than continuous exposure. Some materials can experience a relaxation effect when no longer exposed to irradiance. 7 Evaluation criteria 8 Information to be given in the test report |
