European foreword
This document (EN 14805:2022) 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 October 2022, and conflicting national standards shall
be withdrawn at the latest by October 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14805:2008.
In comparison with the previous edition EN 14805:2008, the following technical modifications have
been made:
a) modification of 7.3 on transportation regulations and labelling, adding the sentence “The user must
be aware of the incompatibilities between transported products.”;
b) modification of 7.4 on marking. The requirements of marking are also applied to the accompanying
documents;
c) deletion of reference to EU Directive 67/548/EEC of June 27, 1967 in order to take into account the
latest Regulation in force (see [2]);
d) EU Directive 98/83/EC (see [1]) of 3 November 1998 shall be taken into account the latest
Regulation in force for drinking water.
e) modification of moisture content in Table 2, to be in line with EN 973:2009 and EN 16401:2013.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
