Foreword
This document (EN 902:2009) has been prepared by Technical Committee CEN/TC 164 “Water supply”, the
secretariat of which is held by AFNOR.
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by endorsement, at the latest by July 2009, and conflicting national standards shall be withdrawn at the latest by
July 2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 902:1999.
The significant technical differences between this edition and EN 902:1999 are as follows:
a) deletion of the reference to EU Directive 80/778/EEC of July 15,1980 in order to take into account the latest
Directive in force (see [1]);
b) notification that the standard applies to pure chemical and not to mixtures with other chemicals;
c) replacement of ISO 5666-1 by EN 1483;
d) use of the changed classification and labelling (see [2]).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic,
