4 General requirements for goggles
4.1 Physiological compatibility
Goggles shall be designed and manufactured in such a way that, when used under the conditions and for the purposes intended, they will not compromise the health or safety of the wearer. The risks posed by substances leaking or evaporating from the goggles that can come Into prolonged contact with the wearer shall be reduced by the manufacturer to within the limits of any applicable regulatory requirement.
Special attention shall be given to substances that are allergenic, carcinogenic, mutagenic or toxic to reproduction.
NOTE I Excessive pressure due to a poor (it on the head, chemical irritation or allergy are known to produce reactions, Rare or Idiosyncratic reactions to any material arc known to occur and the individual wearer Is well advised to avoid those types ot frame materials.
Substances recommended for cleaning, maintenance or disinfection shall be known to be unlikely to have any adverse effect upon the wearer, when applied in accordance with the instructions given in the Information to be supplied by the manufacturer.
Manufacturers/suppliers shall perform an appropriate risk analysis on potentially harmful substances contained in the goggles such that, when the goggles are used under the conditions and for the purposes intended, the health (and safety) of the wearer shall not be compromised.
The following are examples of documents that represent the appropriate information:
a) specification of the material(s);
b) safety data sheets relating to the materials;
c) information relating to the suitability of the materials for use with food, in medical devices, or other relevant applications;
d) Information relating to toxicological, allergenic, carcinogenic, toxic to reproduction, or mutagenic investigations on the materials.
NOTE 2 SpecIfic national regulations with regard to the restriction of certain chemical substances need lobe observed, for example release of nickel,
4.2 Construction and adjustment
Areas of the goggles that may, during intended use, come into contact with the wearer shall be free from projections, sharp edges or other features likely to cause discomfort or injury to the wearer.
Any part of the goggles that can be adjusted or removed by the wearer for the purpose of replacement (In accordance with the instructions given In the Information to be supplied by the manufacturer) shall facilitate adjustment, removal and attachment without the use of tools.
Any adjustment system incorporated In the goggles shall maintain the intended fit for the foreseeable conditions of use.
The test shall be carried out by physical Inspection according to ISO 18526-3:2020, 6.1.
4.3 Cleaning and/or disinfection
The goggles shall be cleaned only once according to the cleaning and/or disinfection procedures in the information to be supplied by the manuficturer before being subjected to testing.
4.4 Lens material and surface quality
In a circular area 30’ mm diameter centred on the reference point(s) but excluding a marginal area 5,. mm wide around the edge of the lens if this overlaps with the circular area, lenses shall be free from defects likely to impair vision in use (such as bubbles, scratches, inclusions, dull spots, pitting. mould marks, scouring, grains, pocking, scaling and undulation) when examined according to ISO 18526-3:2020, 6.6
4.5 Headform(s)
Unless the manufacturer specifies the headform(s) according to ISO 18526-4 that is/are compatible with the goggles, the test methods where (a) headformsJ is/are required shall use the headlorm l-M according to ISO 18526-4 as the default,
4.6 Retention by headband and harnesses (sit and fit)
Goggles shall sit in the intended position during normal use and shall adapt to the contours of the face. The headband shall be designed to be flexible or adjustable and sit securely on the back of the head or a helmet. The headband assembly shall not cause any discomfort nor exhibit any insecurity when tested in accordance with ISO 18526-3:2020, 6.5.
4.7 Mandatory and optional requirements
In this document both optional and mandatory requirements are described. Depending on the intended use and/or the manufacturer’s claimed specification, some requirements marked as optional become mandatory.
5 Transmittance of the lenses
5.1 General
Transmittance values shall be determined in accordance with ISO 18526-2:2020. Clauses 6 to 11, as appropriate. Luminous transmittance shall be calculated using CIE standard illuminant D65 in accordance with ISO 11664-2 (see also ISO 4007:20 18, 3. 10.1.32).
5.2 Transmittance categories
Depending upon the mean luminous transmittance, V.D6S. at their reference points, lenses for downhill ski ing and snowboarding use shall be attributed to one of the five tint categories in Table 1.
The ranges of the luminous transmittance, TvD65, of these live categories are given by the values in
Table 1. There are only three descriptive groups for use by consumers as shown in Table 7. An overlap
of the transmittance values shall he not more than ±2 % (absolute) between the categories 0, 1,2 and 3.
There is no overlap in transmittance values between categories 3 and 4.
