European foreword
This document (EN 882:2016) 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 September 2016, and conflicting national standards
shall be withdrawn at the latest by September 2016.
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 882:2004.
Significant technical differences between this edition and EN 882:2004 are as follows:
a) addition of chemical names for aluminium sodium dioxide and for aluminium sodium tetrahydroxide;
b) replacement of warning and safety precautions notes by labelling according to Regulation (EC) No
1272/2008.
