Commission Implementing Decision (EU) 2026/79 of 12 January 2026 amending Commission Implementing Decision (EU) 2025/165 as regards harmonised standards for seamless steel tubes, butt-welding pipe fittings, copper and copper alloys, unfired pressure vessels, flanges and their joints, industrial valves, and safety devices for protection against excessive pressure, drafted in support of Directive 2014/68/EU of the European Parliament and of the Council (Text with EEA relevance) 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 OJ L 316, 14.11.2012, p. 12, ELI: http://data.europa.eu/eli/reg/2012/1025/oj. , 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 Directive 2014/68/EU of the European Parliament and the Council of 15 May 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of pressure equipment (OJ L 189, 27.6.2014, p. 164, ELI: http://data.europa.eu/eli/dir/2014/68/oj). , 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 set out in Annex I to that Directive covered by those standards or parts thereof. (2) By Implementing Decision C(2024) 1241 Commission Implementing Decision C(2024) 1241 final of 1 March 2024 on a standardisation request to the European Committee for Standardization and the European Committee for Electrotechnical Standardization as regards pressure equipment and assemblies in support of Directive 2014/68/EU of the European Parliament and of the Council. , the Commission made a request to the European Committee for Standardization (CEN) and the European Committee for Electrotechnical Standardization (Cenelec) for drafting of new harmonised standards, the revision of existing harmonised standards and the completion of the work on draft harmonised standards in support of Directive 2014/68/EU. (3) On the basis of the request set out in Implementing Decision C(2024) 1241, CEN revised harmonised standard EN 10216-2:2013 for seamless steel tubes. This resulted in the adoption of standard EN 10216-2:2024. CEN further revised harmonised standard EN 10253-4:2008 and amendment thereto on butt-welding pipe fittings. This resulted in the adoption of standard EN 10253-4:2025. CEN also completed standards EN 12163:2024, EN 12164:2024, EN 12166:2024, EN 12167:2024 and EN 12168:2024 on copper and copper alloys. CEN also revised harmonised standard EN 12420:2014 on copper and copper alloys. This resulted in the adoption of standard EN 12420:2024 on copper and copper alloys. CEN also revised standard EN 12735-2:2016 on copper and copper alloys. This resulted in the adoption of standard EN 12735-2:2024. CEN further completed standard EN 13445-11:2024 on unfired pressure vessels. CEN also revised standard EN 13445-5:2021 on unfired pressure vessels. This resulted in the adoption of amended standard EN 13445-5:2021+A1:2024. CEN also revised standard EN 1591-1:2013 on flanges and their joints. This resulted in the adoption of standard EN 1591-1:2024. CEN further revised standard EN 16668:2016+A1:2018 on industrial valves. This resulted in the adoption of standard EN 16668:2025. CEN further completed standard EN 1982:2024 on copper and copper alloys. CEN lastly completed standard EN ISO 4126-10:2024 on safety devices for protection against excessive pressure.

(4) The Commission together with CEN has assessed whether those standards for pressure equipment as drafted by CEN comply with the request set out in Implementing Decision C(2024) 1241. (5) Those standards satisfy the requirements which they aim to cover, and which are set out in Annex I to Directive 2014/68/EU. It is therefore appropriate to publish the references of those standards in the Official Journal of the European Union. (6) Commission Implementing Decision (EU) 2025/165 Commission Implementing Decision (EU) 2025/165 of 30 January 2025 on the harmonised standards for pressure equipment drafted in support of Directive 2014/68/EU of the European Parliament and of the Council (OJ L, 2025/165, 31.1.2025, ELI: http://data.europa.eu/eli/dec_impl/2025/165/oj). provides in Annex I thereto the references of harmonised standards conferring a presumption of conformity with Directive 2014/68/EU. In order to ensure that the references of harmonised standards drafted in support of Directive 2014/68/EU are listed in one act, the references of the harmonised standards EN 10216-2:2024, EN 10253-4:2025, EN 12163:2024, EN 12164:2024, EN 12166:2024, EN 12167:2024, EN 12168:2024, EN 12420:2024, EN 12735-2:2024, EN 13445-11:2024, EN 13445-5:2021+A1:2024, EN 1591-1:2024, EN 16668:2025, EN 1982:2024, and EN ISO 4126-10:2024 should be included in that Annex. (7) It is necessary to withdraw from the L series of the Official Journal of the European Union the references of the harmonised standards EN 10216-2:2013, EN 10253-4:2008 and amendment thereto, EN 12420:2014, EN 12735-2:2016, EN 13445-5:2021, EN 1591-1:2013, and EN 16668:2016+A1:2018, given that they have been revised. It is therefore appropriate to delete these references from Annex I to Implementing Decision (EU) 2025/165. (8) In order to give manufacturers sufficient time to adapt their products to the revised versions of harmonised standards EN 10216-2:2013, EN 10253-4:2008 and amendment thereto, EN 12420:2014, EN 12735-2:2016, EN 13445-5:2021, EN 1591-1:2013, and EN 16668:2016+A1:2018 it is necessary to defer the withdrawal of the reference of those standards. (9) Implementing Decision (EU) 2025/165 should therefore be amended accordingly. (10) Compliance with a harmonised standard confers a presumption of conformity with the corresponding essential requirements set out in Union harmonisation legislation from the date of publication of the reference of such standard in the Official Journal of the European Union. This Decision should therefore enter into force on the day of its publication, HAS ADOPTED THIS DECISION:
