This document specifies requirements, dimensions and tolerances for pipes and fittings of longitudinallywelded, hot-dip galvanized steel pipe with spigot and socket used for vacuum drainage systems inside andoutside buildings and for gravity and vacuum drainage systems on ships and floating maritime structures 1) :.above freeboard deck as long as the heeling is taken into account in the event of damage when installedabove freeboard deck on passenger ships;.inside a watertight compartment below freeboard deck;.with direct connection to the outboard (not permitted below freeboard deck);.inside tanks as long as these are not filled with foreign media and are not cargo tanks.On well-anchored maritime structures, this standard applies to pipes and fittings of longitudinally welded hot-dipgalvanized steel pipe with spigot and socket used in drainage systems in the living area.NOTE Pipes and fittings according to this document may also be used in central vacuum cleaning installations, invacuum suction lifting installations, in chip transporting installations and in other waste water and process pipes as long asthe media to be discharged do not damage the components or the health and safety of the personnel.For other pipes, this document only applies if agreed with the relevant operators and following priorconsultation with the manufacturer.This document contains a designation system for the different types of pipes and fittings for easy identificationof each component.This document is only applicable in conjunction with EN 1123-1. It does not apply to the marking of productsfor which EN 1123-1/A1 is applicable.
