This draft European Standard is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical
Committee CEN/TC 164.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

Foreword
This document (FprEN 12518:2013) has been prepared by Technical Committee CEN/TC 164 “Water supply”,
the secretariat of which is held by AFNOR.
This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede EN 12518:2008.
The significant technical difference between this edition and EN 12518:2008 is the deletion of the reference to
EC Directive 80/778/EEC of July, 15 1980 in order to take into account of the last Directive in force (see [1]).

Introduction
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by this European Standard:
a) this European Standard provides no information as to whether the product may be used without
restriction in any of the Member States of the EU or EFTA;
b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national
regulations concerning the use and/or the characteristics of this product remain in force.
NOTE Conformity with this European Standard does not confer or imply acceptance or approval of the product in any
of the Member States of the EU or EFTA. The use of the product covered by this European Standard is subject to
regulation or control by National Authorities.

1 Scope
This European Standard is applicable to high-calcium lime used for treatment of water intended for human
consumption. It describes the characteristics of high-calcium lime and specifies the requirements and the
corresponding test methods for high-calcium lime. It gives information on its use in water treatment. It also
determines the rules relating to safe handling and use (see Annex B).
