Foreword
This document (prEN 1123-2:2005) has been prepared by Technical Committee CEN/TC 165 “Waste water
engineering”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1123-2:1999.
This document on pipes and fittings of longitudinally welded hot-dip galvanized steel pipe with spigot and
socket for waste water systems consists of the following Parts:
Part 1: Requirements, testing, quality control;
Part 2: Dimensions
Part 3: Dimensions and special requirements for vacuum drainage systems and for drainage systems in
shipbuilding

Introduction
Pipes and fittings of longitudinally welded hot-dip galvanized steel pipes with spigot and socket for waste
water systems as specified in this document are used in gravity drainage systems in buildings. For vacuum
drainage systems and for drainage systems in shipbuilding, it was necessary to specify additional
requirements and further dimensional specifications for components and joints used in these systems.
Components specified in this EN 1123-3 are used for vacuum drainage systems and for drainage systems in
shipbuilding.

1 Scope
This standard applies to pipes and fittings of longitudinally welded hot-dip galvanized steel pipes with spigot
and socket for waste water systems. It specifies dimensions and tolerances for pipes, fittings, pipe connectors
and seals and establishes a system of designations for the different pipe and fitting types that conform to the
stated requirements. This standard is only valid in connection with EN 1123-1. This standard does not apply
to the marking of products. EN 1123-1 applies to the marking.
