Describes reference test methods for determining the properties of sunglasses given in ISO 12312 (all parts).

This International Standard specifies reference test methods for determining the properties of sunglasses given in ISO12312 (all parts). It is applicable to all sunglasses and related eyewear. Other test methods may be used if proven to be equivalent.
