European foreword
This document (prEN 1302:2023) 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 1302:1999.
In comparison with the previous edition, the following technical modifications have been made:
— Replacement of the withdrawn aluminium product standards EN 881 and EN 883 by EN 17034.
— Replacement of the withdrawn mercury analysing standard ISO 5666-1:1983 by ISO 12846:2012.
— Removal of the withdrawn standard ISO 6382:1981. As there was no replacement, the analysing
method for silicon content based on this standard was removed.
— Removal of routine methods used for determinate arsenic. Method: Silver diethyldithiocarbamate
spectrophotometric method based on standard ISO 6595:1982 as this standard has been
withdrawn without replacement.
— Removal of routine methods used for determinate iron. Method: 1,10-Phenanthroline
spectrophotometric method based on standard ISO 6685:1982 as this standard has been
withdrawn without replacement.
2+
— Removal of a method for determination of iron (total and Fe ) (volumetric method) as EN 5790
has been removed as the standard has been withdrawn without replacement. Furthermore, the
method uses potassium dichromate and there are other options for iron determination.
— Update of the clause titles to correspond the CEN Standard form.
— Update of Table 1 and 2 to correspond the analytical methods available in the standard.

4 Methods of analysis
The methods of analysis are used to analyse the product quality. Table 1 lists the methods which shall
be used for analysis of aluminium-based coagulants composition as commercial product and the
principles of each method. The reference methods which shall be used are described in full in
Annexes A and B. Other methods can be used for quality control.
Table 2 lists the methods which shall be used for analysis of main by-products and chemical
parameters. These are applicable to all aluminium based coagulants (EN 878, EN 882, EN 885, EN 886,
EN 887, EN 935 and EN 17034). The relevant limit value for each coagulant is available in the product
standard.
