Cenelec revised existing harmonized standard EN 50581:2012 which led to the adoption of standard EN IEC 63000:2018 setting out specifications for the technical documentation required for assessing materials, components and electrical and electronic equipment with respect to the restriction of the use of certain hazardous substances. That new standard EN IEC 63000:2018 is based on existing international standard IEC 63000:2016 which itself is based on harmonized standard EN 50581:2012.

Commission Implementing Decision (EU) 2020/553 of 21 April 2020 was published in the Official Journal L 127/22 of the EU amending the list of harmonized standards published under the Radio Equipment Directive.
