European foreword
This document (EN 15655-2:2020) has been prepared by Technical Committee CEN/TC 203 “Cast iron
pipes, fittings and their joints”, 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 May 2021, and conflicting national standards shall be
withdrawn at the latest by May 2021.Attention is drawn to the possibility that some of the elements of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
