ISO/TS 24348:2007 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 micrograms per square centimetre per week.
ISO/TS 24348:2007 aims to control those spectacle frames that, if produced with materials and/or surface treatments containing nickel, can be worn by nickel-sensitized persons.
