AS NZS 18527.1:2022 pdf free download – Eye and face protection for sports usePart 1: Requirements for downhill sking and snow boarding goggles(ISO 18527-1:2021,MOD).
This document applies to all goggles with piano lenses, intended for eye protection against hazards including ultraviolet and visible solar radiation, rain, snow and wind, during downhill skiing. snowboarding and other similar activities.
This document applies to downhill skiing and snowboarding goggles fitted with an insert to carry prescription lenses.
It specifies requirements and testing for materials, performance, marking of goggles and information to he supplied by the manulacturer.
Information on the selection and use of downhill skiing and snowboarding goggles is given in Annex A. This document does not apply to
a) eye protectors for protection when operating or travelling on a motorized vehicle,
b) eye protectors for protection against optical radiation from artificial sources, such as those used in solarla,
c) eye protectors for direct observation of the sun, and
d) eye protectors intended for sports with unrelated hazards and risks.

3 Terms and definitions
For the purposes of this document, the terms and the definitions given in Iso 4007 apply.
NOTE 2 Lenses of tint category 0 do not have any useful polarizing effect.
5.5.3 Gradient-tinted lenses
5.5.3.1 General
Uniformity of transmission is subiect to the requirements at S.4.1. and s.4.i,i
5.5.3.2 Determination of the tint category
The tint category of gradient-tinted lenses shall be determined by the luminous transmittance at the reference point.
5.6 Claimed transmittance and reflectance properties (optional requirements)
5.6.1 General
In the case where specific transmittance values are claimed, these claims shall be according to 5.6.2 and 5.6.3. These requirements shall apply within a 10 mm radius circle centred on the reference point.
5.6.2 Solar blue-light absorption/transmittance
a) Solar blue-light absorption – In the case where It is claimed that a lens has x % solar blue- light absorption, the solar blue-light transmittance. TSB. of the lens, measured according to ISO 18526-2:2020, 9.1, shall not exceed (100.5 – x) %.
b) Solar blue-light transmittance In the case where It is claimed that a lens has less than x% solar blue-light Lranmittance, the solar blue-light transmittance, tSH. of the lens, measured according to ISO 18526-2:2020,9.1, shall not exceed (x + 0,5) %.
For the calculation of the blue-light transmittance, the values of ISO 18526-2:2020, Table DI shall be used.
5.6.3 Solar IJY absorptlon/transmlttance
Requirements for the maximum transmittance of lenses in the UV-A and the UV-B shall be as given In Table 1 as appropriate. In cases where It Is claimed that a lens provides a certain percentage UV absorption or UV transmittance that is better than the requirement in Table 1, corresponding requirements shall apply.
For the calculation of the values of UV absorption/transmittance the values of Iso 18526-2:2020, Table D.1 shall be used,
a) Solar UV absorption – In the case where it is claimed that a lens has x % UV absorption, the solar DV transmittance of the lens, tSUV.380 measured according to ISO 18526-2:2020, 8.3, shall not exceed (100.5 — t) %.
b) Solar DV transmittance – In the case where it is claimed that a lens has less than x % DV transmittance, the solar LIV transmittance of the lens, SUV,380. measured according to ISO 18526-2:2020. 83, shall not exceed (x + 0.5) %.
