Foreword
This document (FprEN 878:2015) 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 878:2004.
Significant technical differences between this edition and EN 878:2004 are as follows:
a) deletion of the reference to EU Directive 80/778/EEC of 15 July 1980;
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".
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by this standard:
d) this 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;
e) 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 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 aluminium sulfate used for treatment of water intended for human
consumption. It describes the characteristics of aluminium sulfate and specifies the requirements for aluminium
sulfate and gives reference to the analytical methods. It gives information on its use in water treatment. It also
determines the rules relating to safe handling and use of aluminium sulfate (see Annex B).
