Page 3 EN 1253-1:1999 BSI 09-1999 1 Scope This European Standard classifies gullies, gives guidance for places of installation and specifies requirements for the const
23、ruction, design, performance and marking of factory made gullies for buildings, irrespective of material, for use in drainage systems operating under gravity including siphonic systems. NOTEAlthough normally used to convey domestic waste water, industrial waste water and rainwater, gullies can conve
24、y 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 references This European Standard incorporates by dated or undated reference, provisions from
25、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 publications apply to this European Standard only when incorporated in it by amendment
26、 or revision. For undated references the latest edition of the publication referred to applies.

41、h, when tested in 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 installation 5.1 General A guide for selecting the c
42、lass 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 1,5 Unused flat roofs such as felt-and-gravel roofs, gravel fill roofs and similar. Class K 3 Areas without vehicular traffic, such as bathroo
43、ms 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 15 Areas with light vehicular traffic, excluding f
