NEN-EN-ISO 4618 defines terms used in the field of coating materials (paints, varnishes and raw materials for paints and varnishes). Terms relating to specific applications and properties are dealt with in standards concerning those applications and properties, eg corrosion protection, coating powders. Terms on nanotechnologies are harmonized with ISO / TS 80004-4. In addition to terms in English and French (two of the three official ISO languages), this International Standard gives the equivalent terms in German; these are published under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
