European foreword
This document (EN 887:2016) 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withdrawn at the latest by September 2016.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 shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 887:2004.
Significant technical differences between this edition and EN 887:2004 are as follows:
a) addition of CAS Registry Numbers for aluminium sulfate tetradecahydrate, hexadecahydrate and
octadecahydrate;
b) addition of normative reference concerning the determination of iron (III) sulfate;
c) replacement of warning and safety precautions notes by labelling according to Regulation (EC) No
1272/2008”.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
