THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) No 1025/2012 of the European Parliament and of the Council of 25 October 2012 on European standardisation, amending Council Directives 89/686/EEC and 93/15/EEC and Directives 94/9/EC, 94/25/EC, 95/16/EC, 97/23/EC, 98/34/EC, 2004/22/EC, 2007/23/EC, 2009/23/EC and 2009/105/EC of the European Parliament and of the Council and repealing Council Decision 87/95/EEC and Decision No 1673/2006/EC of the European Parliament and of the Council (1), and in particular Article 10(6) thereof,

Whereas:

| (1) | In accordance with Article 12 of Directive 2014/68/EU of the European Parliament and of the Council (2), pressure equipment or assemblies referred to in Article 4(1) and (2) of that Directive which are in conformity with harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union, are to be presumed to be in conformity with the essential safety requirements covered by those standards or parts thereof referred to in Annex I to that Directive. |

(1)

In accordance with Article 12 of Directive 2014/68/EU of the European Parliament and of the Council (2), pressure equipment or assemblies referred to in Article 4(1) and (2) of that Directive which are in conformity with harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union, are to be presumed to be in conformity with the essential safety requirements covered by those standards or parts thereof referred to in Annex I to that Directive.

| (2) | By letter M/071 of 1 August 1994 the Commission made a request to the European Committee for Standardisation (CEN) for drawing up, in relation to the pressure equipment, the product related standards and the standards of a horizontal nature in support of Directive 97/23/EC of the European Parliament and of the Council (3). That Directive was replaced by Directive 2014/68/EU without changing the essential safety requirements referred to in Annex I to Directive 97/23/EC. |

(2)

By letter M/071 of 1 August 1994 the Commission made a request to the European Committee for Standardisation (CEN) for drawing up, in relation to the pressure equipment, the product related standards and the standards of a horizontal nature in support of Directive 97/23/EC of the European Parliament and of the Council (3). That Directive was replaced by Directive 2014/68/EU without changing the essential safety requirements referred to in Annex I to Directive 97/23/EC.

| (3) | On the basis of the request M/071 and in order to reflect the state of the art, CEN revised and amended some of the existing harmonised standards. Specifically, CEN revised harmonised standards EN ISO 4126-3:2006, EN 12542:2010 and EN 13175:2014 which resulted in adoption of harmonised standards EN ISO 4126-3:2020 on safety devices, EN 12542:2020 and EN 13175:2019+A1:2020 on LPG equipment and accessories; harmonised standard EN 12735-1:2016 which resulted in adoption of harmonised standard EN 12735-1:2020 on copper and copper alloys; and harmonised standard EN 12953-5:2002 which resulted in adoption of harmonised standard EN 12953-5:2020 on shell boilers. CEN also revised harmonised standards EN 14276-1:2006+A1:2011 and EN 14276-2:2007+A1:2011 which resulted in adoption of harmonised standards EN 14276-1:2020 and EN 14276-2:2020 on pressure equipment for refrigerating systems and heat pumps as well as harmonised standard EN ISO 15620:2000 which resulted in adoption of harmonised standard EN ISO 15620:2019 on welding. |

On the basis of the request M/071 and in order to reflect the state of the art, CEN revised and amended some of the existing harmonised standards. Specifically, CEN revised harmonised standards EN ISO 4126-3:2006, EN 12542:2010 and EN 13175:2014 which resulted in adoption of harmonised standards EN ISO 4126-3:2020 on safety devices, EN 12542:2020 and EN 13175:2019+A1:2020 on LPG equipment and accessories; harmonised standard EN 12735-1:2016 which resulted in adoption of harmonised standard EN 12735-1:2020 on copper and copper alloys; and harmonised standard EN 12953-5:2002 which resulted in adoption of harmonised standard EN 12953-5:2020 on shell boilers. CEN also revised harmonised standards EN 14276-1:2006+A1:2011 and EN 14276-2:2007+A1:2011 which resulted in adoption of harmonised standards EN 14276-1:2020 and EN 14276-2:2020 on pressure equipment for refrigerating systems and heat pumps as well as harmonised standard EN ISO 15620:2000 which resulted in adoption of harmonised standard EN ISO 15620:2019 on welding.
