The light source for indoor lighting environment is specified in ISO 14605. A halophosphate or triphosphor fluorescent lamp with a correlated colour temperature of between 3 800 K to 4 500 K shall be used. When a triphosphor fluorescent lamp is used for evaluating, the fluorescent lamp of the CIE 1974 general colour rendering index (Ra) defined by CIE 13.3 higher than 80 shall be selected. A UV sharp cut off filter specified in ISO 14605 shall be used under UV cut-off condition. The test specimen shall be irradiated uniformly through the window by the light source. The light source that requires warming up shall be equipped with a shutter. The distance between the light source and the chamber shall be adjusted so that the illuminance on the test specimen surface is 1 000 lx±50 lx. The irradiance along the length of the test specimen shall also be constant within±5 %. The illuminance shall be measured with an illuminance meter which has been calibrated by a calibration laboratory. Reflection plate of luminaire and a shielding device of the reactor from external light are to show small or constant absorption in UV and indoor light. The reactor shall be shielded from external light if necessary.
Recovery tests shall be performed in the test chamber by introducing supply air with the same formaldehyde concentration as to be used in the performance test and then comparing air measurement results at the outlet and inlet of the test chamber. The mean recovery shall be greater than 80 %. The results of the recovery test shall be reported (expected concentration versus concentration measured).
NOTE Sink effect, leakage or poor calibration can cause difficulties in meeting minimum requirements for the test.
The test chamber shall be cleaned in order to fulfil the requirements of 7.2.2. Cleaning can be done by washing the inner surface of the test chamber with a detergent followed by two separate rinsing with freshly distilled water. The test chamber is then dried and purged under test conditions. The test chamber can also be cleaned by thermal desorption.
For cleaning of the test chamber, an oven may be used to volatilize any aldehydes or VOCs on the internal wall of the test chamber. Alternative methods can be used instead of an oven.ISO 18560-1 pdf free download.
