Rationale. The Phase 2 protocol is a simple procedure for evaluating di- rect and indirect sunlight photolysis rate constants of a chemical at a spe- cific time of year and latitude. It pro- vides a rough rate constant for the chemical in SHW that is necessary for Phase 3 testing. By comparison with the direct photoreaction rate constant, it can be seen whether the chemical is subject to indirect photoreaction and whether Phase 3 tests are necessary.
