Foreword
This document (EN 13237:2003) has been prepared by Technical Committee CEN/TC 305 "Potentially explosive
atmospheres - Explosion prevention and protection", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latest
by December 2003.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.
Annex A is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard has been produced to assist designers, manufacturers and other interested parties to use
harmonised terms and definitions (vocabulary) for equipment and protective systems intended for use in potentially
explosive atmospheres. It describes the vocabulary to be used to give all standards in this area an overall
uniformity of terminology. Throughout this European Standard, the only hazard considered is the explosion of an
explosive atmosphere.
1 Scope
This European Standard specifies terms and definitions (vocabulary) to be used in suitable standards dealing with
equipment and protective systems intended for use in potentially explosive atmospheres.
NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive
atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The
present standard is not intended to provide means of complying with the essential health and safety requirements
of Directive 94/9/EC.
