which is held by din.this european standard shall be given the status of a national standard, either by publication of an identical text, or by endorsement, at the latest by october 1999, and conflicting national standards shall be withdrawn at the latest by october 1999.according to the cen/cenelec internal regulations, the national standards organizations of the following countries are

sweden, switzerland and the united kingdomforeword 21 scopethis european standard classifies gullies, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking of factory made gullies for buildings, irrespective of material, for use in drainage systems operating under gravity including siphonic systems.note although normally used to convey domestic waste water, industrial waste water and rainwater, gullies can convey other waste water provided there is no risk of damage to components or of injury to health.this european standard does not apply to gully tops and manhole tops which are specified in en 124.2 normative referencesthis european standard incorporates by dated or undated reference, provisions from other publications. these normative references are cited at the appropriate places in the text and the publications are listed hereafter. for dated references, subsequent amendments to or revisions of any of these

accordance with en 1253-2:1998, clause 4, into the following classes: h 1,5, k 3, l 15, m 125.gullies not accessible to either vehicular or foot traffic or not required to withstand external loads are not classified.5 places of installation5.1 generala guide for selecting the class of gully appropriate to the place of installation is given below. the selection of the appropriate class is the responsibility of the specifier.class h 1,5unused flat roofs such as felt-and-gravel roofs, gravel fill roofs and similar.class k 3areas without vehicular traffic, such as bathrooms in dwellings, old peoples homes, hotels, schools, swimming baths, public wash and shower facilities, balconies, loggias, terraces and roofs with greenery.non-load bearing gullies in bathrooms shall fulfil the requirements of class h 1,5.class l 15areas with light vehicular traffic, excluding fork-lift trucks, in commercially used premises.class m 125areas with vehicular traffic, such as car parks, factories and workshops.class c 250 to f 900 gullies and tops conforming to en 124 shall be used for all areas subject to special stresses, such as exhibition halls, market halls, factory sheds and aircraft hangars.5.2 exceptionsnon-load bearing gratings for places of installation which are not accessible to vehicles and pedestrians (protected by suitable masonry surroundings) and which are not covered by the places of installation listed above nor by en 124 shall at least conform tothe test requirements given in en 1253-2:1998, clause 4.6 nominal sizesrecommended nominal sizes are defined by internal diameter of outlet (dn/id) and by external diameter of outlet (dn/od) as follows.nominal sizes dn/id:30; 40; 50; 70; 75; 100;125; 150; 200nominal sizes dn/od:32; 40; 50; 63; 75; 90;100; 110; 125; 160; 200note other nominal sizes which are at present in use are permissible, but they may be reconsidered in the future.7 materialsmaterials shall withstand domestic waste water up to a temperature of 95 8c and industrial waste water as specified by the specifier.materials for roof outlets shall be resistant to rainwater and, when needed, to hot bitumen.materials shall withstand the stresses likely to occur during installation and operation.gullies made of materials which are not inherently corrosion-resistant shall be protected by corrosion prevention.8 design and construction8.1 generalgullies shall be capable of being connected to pipework systems covered by relevant european standards and, when installed in accordance with the manufacturers instructions, shall form an integral part of the building. there shall be no movement possible between the gully and the floor or roof construction, which would impair the functioning of the installed gully.in areas where a pressure test of the pipe system is necessary, gullies for use in the ground floor shall enable such tests to be performed.the upper surfaces of frame and grating shall be flush, except in unused flat roofs. when in position, it shall not be possible for gratings and covers to be dislodged from the frame, but they shall be easy to release.bell traps shall be prevented from floating or becoming displaced by a design feature such as fixing or weight.gullies and their components shall be resistant to normal actions of mechanical, chemical and thermal character.gullies shall be delivered with installation instructions. all joints to and from the gully shall be designed to bewatertight in accordance with pren 476.8.2 appearanceinternal and external surfaces shall be free from sharp edges and imperfections which could impair functioning or risk injury to persons.8.3 depth of water sealtrapped gullies for waste water shall provide a minimum depth of water seal of 50 mm and shall be tested in accordance with en 1253-2:1998, 5.1.note some drainage systems can require depths of water seal greater than 50 mm.8.4 resistance of water seal to pressurewhen tested in accordance with en 1253-2:1998, 5.2, the applied pressure which just causes passage of air shall be 400 pa.8.5 apertures in gratingsapertures can be holes or slots of any shape. permissible aperture dimensions
