- Simulation of wear and corrosion;
- EIS coating test (optional);
- Laboratory test: Release of nickel and its quantitative analytical detection.
This document applies to those parts of metal spectacle frames and those metal parts of combination spectacle frames that come into direct and prolonged contact with the skin of the wearer. This document also applies to those relevant metal parts of articles for eye and face protection, including sunglasses.
The EIS coating test method can be applied only to metal parts which have been coated with an organic, electrically insulating, layer.
