22、tings of longitudinally welded hot-dip galvanized steel pipes with spigot and socket for waste water systems as specified in EN 1123-2 are used in gravity drainage systems in buildings. For vacuum drainage systems and for drainage systems in shipbuilding, it was necessary to specify additional requi

23、rements and further dimensional specifications for components and joints used in these systems. Components specified in this document are used for vacuum drainage systems and for drainage systems in shipbuilding. 1 Scope This document specifies requirements, dimensions and tolerances for pipes and f

24、ittings of longitudinally welded, hot-dip galvanized steel pipe with spigot and socket used for vacuum drainage systems inside and outside 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 ac

25、count in the event of damage when installed above 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 ta

26、nks. On well-anchored maritime structures, this standard applies to pipes and fittings of longitudinally welded hot- dip galvanized 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 cle

27、aning installations, in vacuum suction lifting installations, in chip transporting installations and in other waste water and process pipes as long as the 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 agr

28、eed with the relevant operators and following prior consultation with the manufacturer. This document contains a designation system for the different types of pipes and fittings for easy identification of each component. This document is only applicable in conjunction with EN 1123-1. It does not app

29、ly to the marking of products for which EN 1123-1/A1 is applicable. 2 Normative references The following referenced documents are indispensable for the application of this document.
