This document classifies floor gullies for domestic waste water for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking of factory made gullies for buildings, irrespective of the material, for use in drainage systems requiring a trap with a depth of water seal less than 50 mm (referred to as floor gullies). NOTE Floor gullies with a depth of water seal less than 50 mm are not covered by EN 1253 1, EN 1253 7 and EN 1253 8. These products are intended to be installed where the three following conditions are met: - space limitation will not accommodate a gully with a 50 mm water seal; - the building does not exceed a ground-floor and three floors above; - at least two domestic sanitary appliances are installed in addition to the gully but with only one WC on the same branch (connection pipe) or secondary or branch ventilation is installed (see EN 12056 2:2000, 4.3.2 or 4.3.4.

This specification covers hubless cast iron soil pipe and fittings for use in gravity flow applications. These pipe and fittings are intended for non-pressure applications, as the selection of the proper size for sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage. The pipe and fittings shall be iron castings suitable for installation and service for sanitary, storm drain, waste, and vent piping applications. The pipe and fittings shall meet all applicable requirements and tests given in this specification. Tensile test and chemical test shall be made to conform to the requirements specified. The pipe and fittings shall be uniformly coated with a material suitable for the purpose that is adherent, not brittle, and without a tendency to scale.
