European foreword

This document (prEN 891:2020) 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 CEN Enquiry.
This document will supersede EN 891:2004.

In comparison with the previous edition, the following technical modifications have been made:

‒ removed the analytical methods from this standard and referred to EN 17215 as analytical method

standard;

‒ harmonization of the table for elements (Table 2, section 5.4) for all iron product standards;

‒ update of the information of risk and safety labelling of the product to comply with the new regulations

(see 7.2 and [2]).
