Transition to Directive 2014/68/EU

Directive 97/23/EC was fully superseded by directive 2014/68/EU from 20 July 2016 onwards. Article 13 of the new directive (classification of pressure equipment) became effective 1 June 2015, replacing article 9 of directive 97/23/EC.European Commission: Pressure Equipment Directive

In the UK the Pressure Equipment (Safety) Regulations 2016 PE(S)R (Formerly Pressure Equipment Regulations 1999 (PER)) and the Pressure Systems Safety Regulations 2000 apply:UK Legislation
Pressure Equipment Regulations 1999
accessed 16 October 2022 see Health and safety regulations in the United Kingdom. The Health and Safety Executive and the Health and Safety Executive for Northern Ireland are the named enforcement authorities. Some of the provisions included in PE(S)R 2016 apply differently in NI for as long as the Northern Ireland Protocol is in force after UK existing EU.
