CETOP is:
• the communication platform for fluid power in Europe
• an international umbrella organisation for 17 national fluid power associations with
• more than 1,000 member companies all over Europe
CETOP General Secretariat • Lyoner Strasse 18 • 60528 Frankfurt/Main • Germany • e-mail: [email protected] • www.cetop.org November 2008
This poster is not intended to be exhaustive. It is based on the information supplied by national CETOP member associations. We cannot assume responsibility for the correctness of this. All information is subject to change.
ATEX/IECEx: Certification standards identical for electrical equipment. For IECEx and ATEX equipment, possibility to
deliver the certificates based on the same standards. Audit of the quality system for IECEx and ATEX based on common requirements.
