Pressure equipment

What is the Pressure Equipment Directive?

Stakeholders seeking to place their pressure equipment on the EU market must design, manufacture and assess the conformity of pressure equipment with a maximum allowable pressure (PS) greater than 0.5 bar in compliance with the Pressure Equipment Directive (PED) 2014/68/EU. CE marking of the products is mandatory. For products to be eligible for CE marking, the essential safety requirements of the PED must be fulfilled and pressure equipment preferably manufactured according to harmonised standards, including EN 13445, or national codes of practice, such as the AD 2000 Code.

Competent third-party bodies, i.e. authorised “Notified Bodies”, must be involved in the assessment and monitoring of the manufacturers. In February 2018, GSI - Gesellschaft für Schweißtechnik mbH became authorised as a Notified Body (identification number 1182) for products and systems falling under the scope of the Pressure Equipment Directive 2014/68/EU by the Central Authority for Safety of the German Federal States (Zentralstelle der Länder für Sicherheitstechnik, ZLS). GSI is thus authorised to provide the test services required within the scope of conformity assessment in its ZLS-recognised laboratories and at the manufacturer's premises.

As a Notified Body, we support you with the expansion of your product portfolio, the required qualifications and approvals and the quality assurance of your products and with ensuring construction progress. On your behalf, we also perform final assessment of new pressure equipment or audit your QM system.

Manufacturers of pressure vessels and pressure-bearing components in more than 100 countries worldwide rely on the ASME Code. It is the most comprehensive code for the design, manufacture and testing of pressure vessels. Pressure vessel manufacturers require ASME manufacturer certification.

Assurance of the ASME quality standards is verified by authorised inspection agencies (AIAs) such as TÜV Thüringen e.V., whose subsidiary, CIS GmbH Consulting Inspection Services (CIS), provides advisory, training and other services.

Working with CIS, GSI SLV supports you in obtaining product certification according to the ASME Code, offering numerous events and seminars on this topic.
