This document has been developed and written by the Pressure Equipment Consultation Forum (PECF), Safety Assessment Federation (SAFed) and EEMUA in consultation with other stakeholders within the pressure equipment industry to help those parties involved in the creation of pressure equipment assemblies to ensure that global conformity assessment can be successfully applied. The UK Health and Safety Executive (HSE), which was also involved in producing this publication, supports the guidance as a sensible and proportionate approach to managing health and safety.

The Pressure Equipment Directive (PED) requires that individual items of pressure equipment undergo conformity assessment where appropriate. This also applies to assemblies of pressure equipment which need to undergo global conformity assessment and CE marking. Experience within the UK indicates that generally this process works well when assemblies are placed on the market as complete, factory supplied products. However, when assemblies are created on site at the place of installation the legal process of global conformity assessment is often found to be non-compliant. The document is intended to provide the necessary guidance to all parties with responsibilities for the pressure equipment assembly to ensure global conformity assessment can take place.

The guidance applies to the following directives: Pressure Equipment Directive (97/23/EC), as implemented by the Pressure Equipment Regulations (PER) 1999; and Pressure Equipment Directive (2014/68/EU), as implemented by the Pressure Equipment (Safety) Regulations (PESR) 2016.

This publication is aimed at all parties (other than notified bodies or user inspectorates) who are involved in the design and manufacturer of site installed assemblies in the UK. This includes the following parties: end users (including those responsible for procurement of the assembly or appointment of contractors); main contractors; site erection contractors; design consultants; control and instrumentation contractors; piping contractors; commissioning teams.
