Foreword
This European Standard was prepared jointly by a mining working group, convened under SC 31-3,
Intrinsically safe apparatus and systems "i", of Technical Committee CENELEC TC 31, Electrical apparatus
for explosive atmospheres.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as EN 50394-1 on 2003-10-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
 at national level by publication of an identical
 national standard or by endorsement (dop) 2004-10-01
- latest date by which the national standards conflicting
 with the EN have to be withdrawn (dow) 2006-10-01
This European Standard was prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association to set down requirements for the design and construction of
equipment in support of the essential safety and health requirements described in the European Directive
94/9/EC "Equipment and protective systems intended for use in potentially explosive atmospheres".
