EN 1123-2:2006 (E) 5 Introduction Pipes and fittings of longitudinally welded hot-dip galvanized steel pipes with spigot
24、and socket for waste water systems as specified in this European Standard 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
25、 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. EN 1123-2:2006 (E) 6 1 Scope This European Standard applies to pipes and fittings of longitudinally welded hot-dip galvanized steel pipes with spig
26、ot 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 11
27、23-1. This standard does not apply to the marking of products. EN 1123-1 applies to the marking. 2 Normative references The following referenced documents are indispensable for the application of this document.
