European foreword
This document (prEN 1018:2024) 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 1018:2021
prEN 1018:2024 includes the following significant technical changes with respect to EN 1018:2021:
— modification of 7.3 on transportation regulations and labelling, adding the sentence “The user shall
be aware of the incompatibilities between transported products.”;
— modification of 7.4 on marking. The requirements of marking are also applied to the accompanying
documents;
— changes in the requirements for the composition of the porous products (Table 1) and their
impurities (Table 2).
