Photocatalysis. Irradiation conditions for testing photocatalytic properties of semiconducting materials and the measurement of these conditions1 Scope This Technical Specification prescribes the conditions for irradiating photocatalytic surfaces in order to perform photocatalytic efficiency tests. In addition, the measurement and documentation of these irradiation conditions with respect to the spectral distribution, irradiance and homogeneity are given.
