StandardDetails

This Technical Specification specifies methods for accelerated wear and corrosion, to be used prior to the detection of nickel release from coated metal and combination spectacle frames, and for detecting the release of nickel from those parts of metal and combination spectacle frames, whether coated or not, intended to come into direct and prolonged contact with the skin, in order to determine whether such parts release nickel at a rate greater than 0,5 µg/cm2/week. This Technical Specification aims to control those spectacle frames which, if produced with materials and/or surface treatments containing nickel, can be worn by nickel-sensitized persons.
