34、r temperature is between 3800 K to 4500 K (F4000) shall be used for testing of indoor light-acitive photocatalytic materials used under an indoor lighting environment without sunlight. The CIE 1974 general colour rendering index (Ra) defined by CIE 13.3 of halophosphate fluorescent lamp is about 60.
35、 When a triphosphor fluorescent lamp is used for testing, the fluorescent lamp which Ra is higher than 80 shall be selected. Performance specifications of fluorescent lamps are specified in IEC 60081. A typical relative spectral power distribution of the halophosphate fluorescent lamp is shown in Fi

43、r specified in ISO 10677.8 Indoor lighting conditions and selection of UV sharp cut-off filtersTo set three kinds of indoor lighting conditions (condition A, condition B, condition C), the method of selecting the UV sharp cut-off filter is defined.Condition ACondition A is an indoor lighting conditi
44、on by luminaire with cover that transmits optical radiation longer wavelength than 400 nm. In this condition, the type A filter shall be used.Condition BCondition B is an indoor lighting condition by luminaire with cover that transimits optical radiation longer wavelength than 380 nm. In this condit
45、ion, the type B filter shall be used.Condition C6 ISO 2013 All rights reservedBS ISO 14605:2013ISO 14605:2013(E)Condtion C is an indoor lighting condition by luminaire without cover. When evaluating this condition, the UV sharp cut-off filter is not needed in general. However, in general, a fluoresc
46、ent lamp for general lighting service emits very small UV radiation and large amount of visible radiation, and photocatalytic responsivity in UV range is higher than that in visible range. It is necessary to separate UV effects and the visible one. Therefore, to evaluate true performance produced by
47、 only visible radiation, performance evaluation by combination of the UV sharp cut-off filter and the light source shall be done together. The type of filter is defined by each application.9 Measurement and use conditionsa) The illuminance shall be measured with and without a UV sharp cut-off filter
48、, along with the UV irradiance. The illuminance for testing shall be set as a standard value specified in each standard.b) The illuminance and UV irradiance shall be measured at stabilized condition, which is a minimum of 15 min after the light is turned on.c) The illuminance and UV irradiance shall
49、 be measured at start and end of the testing. The lamp shall be replaced when the illuminance has decreased to 70 % of the initial value.d) If a luminaire with a reflection plate is used fot testing, the reflection plate shall be shown small absorption in ultraviolet and visible radiation.e) The transmittance of the UV sharp cut-off filter might be changed by long time irradiation. Therefore, transmittance of the filter shall be measured periodically or the filter shall be replaced periodically.f) If an acrylic
