Test The outer surface of the lamp lenses shall be subjected once or more than once to the action of the sand jet produced as described above. The jet shall be sprayed almost perpendicular to the surface to be tested. The deterioration shall be checked by means of one or more samples of glass placed as a reference near the lenses to be tested. The mixture shall be sprayed until the variation in the diffusion of light on the sample or samples measured by the method described in Appendix 2, is such that: Δ d = (T5 - T4) / T2 ≤ 0.0250 ± 0.0025 Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.
