What is BS EN 1253-1 - Gullies for buildings about?
BS EN 1253 discusses gullies for buildings. BS EN 1253-1 is the first part of BS EN 1253 and discusses trapped floor gullies with a depth water seal of at least 50 mm. Although normally used to convey domestic wastewater, these floor gullies may convey other wastewater, e.g., industrial wastewater, provided there is no risk of damage to components or of injury to health.
BS EN 1253-1 classifies floor gullies 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 of at least 50 mm.
Who is BS EN 1253-1 - Gullies for buildings for?
BS EN 1253-1 on gullies for buildings is useful for:
- Gully trap manufacturers
- Architects
- Civil engineers
- Builders
Why should you use BS EN 1253-1 - Gullies for buildings?
Trapped floor gullies is a discharge fitting the top of which is a grating or cover capable of installation at the ground or floor level, intended to receive wastewater either through apertures in the grating and/or from side inlets and/or channels joined to the body of the gully and to drain that wastewater through the outlet.
BS EN 1253-1 provides you with the requirements for the design and construction of trapped floor gullies. It guides you with the requirements for blockage prevention and places of installation. BS EN 1253-1 provides requirements for materials, thermal behaviour of floor gullies, tightness, mechanical strength, and flow rates.
BS EN 1253-1 provides you with a test method to assess the dimensions of apertures in gratings, the position of side inlets, water seal, blockage prevention, thermal behaviour, loading test, tightness, mechanical strength, and flow rates. BS EN 1253-1 helps you with the marking and evaluation of conformity.
What’s changed since the last update?
BS EN 1253-1:2015 supersedes BS EN 1253-1:2003 and BS EN 1253-2:2003, which are withdrawn. It includes some technical changes. These include:
reduction of scope on trapped floor gullies with a depth of water seal of at least 50 mm for use in gravity
- Drainage systems
- More definitive description of products
- Modification of terms and definitions
- Precision in definition of places of installation
- Consideration of liquid applied membranes as connecting components
