EU Publishes New Sunglasses Testing Standard EN ISO 12312
Vol. 736 | October 21, 2013
In order to demonstrate compliance with the basic health and safety requirements of the EU Personal Protective Equipment (PPE) 89/686/EEC Directive, sunglasses have conformed with the European sunglasses safety standard EN 1836. Recently, two new international standards have been published for sunglasses, which will replace the existing EN 1836 by Feb. 2014 at the latest.
Please note these new standards won’t offer a presumption of conformity to the basic health and safety requirements of the PPE Directive until their references have been published in the EU’s Official Journal.
(a) EN ISO 12312-1:2013 – Eye and face protection – Sunglasses and related eyewear, Part 1: Sunglasses for general use.
(b) EN ISO 12311:2013 – Personal protective equipment – Specifies test methods for sunglasses and related eyewear.
(1) New requirements are specified for transmittance and refractive power.
(2) Wide angle scattering shall not exceed 3% at the reference point.
(3) Resistance to perspiration has been incorporated as a new test, which is technically identical to the method in the European spectacle frames standard EN ISO 12870.
(4) Resistance to abrasion has been added too, as an optional requirement, applying the method per the international standard for abrasion-resistant spectacle lens surfaces ISO 8980-5.
(5) New requirements have been added on the extent of protective coverage that the lenses shall provide for the eyes.
(6) Very dark, special purpose (filter category 4) sunglasses shall provide temporal shielding (wrap around the temple area) to provide at least the same degree of protection from UV and visible light as compared to the forward part of the lenses.
(7) Description of the filter category may now be in the form of a symbol and/or a verbal description.
(8) The design of the “Not suitable for driving and road use” pictogram has been changed to one from ISO 7000, the International graphical symbols standard. This pictogram is required for filters that do not meet the necessary requirements for driving and also for category 4 filters. Minimum height of the pictogram remains at 5 mm.
