Foreword
This document (FprEN 882:2015) 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 882:2004.
Significant technical differences between this edition and EN 882:2004 are as follows:
a) replacement of the reference to EU Directive 80/778 of 15 July 1980 with the latest Directive in force
(see[1]);
b) introduction of an Annex B (normative) giving general rules relating to safety;
c) expansion of Annex A by addition of A.2 "Quality of commercial product".
