Revised text
6.1.3.1 Photochromic sunglare filters
6.1.3.1.1 Conditioning
Unless the manufacturer specifies a different procedure to reach the faded state in the information supplied with
the product, photochromic filters shall be conditioned by the following procedure.
Store samples in the dark at (65 ± 5) °C for (2 ± 0,2) h. Then store in the dark at (23 ± 5) °C for at least 12 h.
6.1.3.1.2 Measurement
NOTE Most photochromic materials respond to normal room lighting and all measurements should therefore be made in
absence of extraneous light.
WARNING Care should be taken to ensure that the radiation used for the measurements does not cause
darkening or bleaching of the sample.
In order to test the variability of the transmittance, a source simulating daylight shall be used. It should approximate
as closely as practicable to the spectral distribution of solar radiation for air mass m = 2 (P. Moon, Journal of the
Franklin Institute, Vol. 230 (1940), pp 583-617, see also CIE 85:1989, Table 6 for the spectral distribution of solar
radiation.) at an illuminance of (50 000 ± 5 000) lux, respecting the values given in Table 6.
Testing shall be done with a Xenon high pressure lamp with filters chosen so that the specified illuminance of
(50 000 ± 5 000) lux and the irradiance values given in Table 5 are reached. The permissible tolerances of the
