Determination of color and transmittance The determination of the chromatic-tone-equal wave-length and transmittance is condu
3、cted according to part 1, cl. 6.8 of these technical delivery conditions. 2.4.1. Color The chromatic-tone-equal wave length of the transmitted light must amount to 570 nm on the whole area. 2.4.2. The glass roof must have following transmittance on the whole area useful for the inspection; light tra

Test at waviness The glasses for sun-roof may not have any waviness which cause strong distortions on the top view of roof. The glasses are tested according to following method: with a projector (according to ECE-R43, cl.
5、9.2.1.2.1), a screen slide AZ is projected according to DIN 52 350 from 4 m distance on a device, in which a mirror of about same size as the glass to be tested in found. The center of the mirror lying horizontally in the device should be found in center of objective. The mirror is bent with the dev
6、ice by 20against the vertical. In 1 m distance from the mirror, a white area (measurement minimum (0.6 x 1.25)m) bent likewise by 20against the vertical. The objective is adjusted so that the black screen lines are sharply illustrated on the white area. Instead of the mirror, the sample to be tested
