The amendments to harmonised standards under the Pressure Equipment Directive (PED) are published in an executive order. These took effect on October 11, 2021. It covers the harmonized standards for:
- metallic industrial piping systems;
- bolted connections for flanges and their joints;
- flame tube boilers made of corrosion-resistant steel.
Article 12 of Directive 2014/68/EU
In accordance with Article 12, pressure equipment or assemblies thereof [1] shall be presumed to conform to the essential safety requirements [2].
[1]: Article 4(1) and (2) refer to assemblies which are in conformity with harmonized standards or parts thereof. The references have been published in the Official Journal of the European Union.
[2] The conformity is with the essential safety requirements described in Annex 1 to the Directive covered by the standards (or parts thereof).
In 1994, the EC made a request (M/071) to the European Committee for Standardization (CEN). In that request, the CEN is asked to draw up both product-related standards and the standards of a horizontal nature in connection with pressure equipment. This is in support of Directive 97/23/EC. Because when that was replaced by Directive 2014/68/EU, the essential safety requirements in Annex 1 did not change.
Standards amended and revised by the CEN
CEN has amended some existing standards. This was done based on the request M/071 and to reflect the state of the art.
Concerning bolted connections for flanges and their joints: The old harmonized standard from 2009 has been replaced by a new harmonized standard (EN 1515-4:2021).
Flame arresters made of corrosion resistant steel: The old harmonized standard from 2003 has been replaced by a new harmonized standard (EN 14222:2021).
Regarding metallic industrial piping systems, the harmonized standard EN 13480-3:2017 has been amended.
Furthermore, CEN together with the Commission verified the compliance of the above measures with request M/071.
