EN 1421:2005 (E) 3 Foreword This European Standard (EN 1421:2005) 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of an identical text or by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn at the latest by December 2005. This document supersedes EN 1421:1996. Significant technical differences between this edition and EN 1421:1996 are as follows: a) deletion of the reference to EU Directive 80/778/EEC of 15 July 1980 in order to take account of the latest Directive in force (see [1]). b) taking into account the new EU Directive 98/83/EC; c) replacement of ISO 5666-1 by EN 1483 and of EN 26595 by EN ISO 11969; d) introduction of EN ISO 11885 for the determination of antimony; e) introduction of Annex B for general rules relating to safety. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
