16、3. This is the first part of EN 1253, a series of standards relating to floor gullies, roof drains and access covers for drainage systems inside buildings. The EN 1253 series under the main title Gullies for buildings will actually consist of the following parts: Part 1: Trapped floor gullies with a

17、 depth water seal of at least 50 mm; Part 2: Roof drains and floor gullies without trap; Part 3: Evaluation of conformity; Part 4: Access covers; Part 5: Gullies with light liquids closure. Since the latest versions of EN 1253-1 and EN 1253-2, the most significant technical changes are the following

18、: a) reduction of scope on trapped floor gullies with a depth of water seal of at least 50 mm for use in gravity drainage systems; b) more definitive description of products; c) modification of terms and definitions; d) precision in definition of places of installation; e) consideration of liquid ap

19、plied membranes as connecting components; f) precision of test conditions for flow rate testing; g) revision of loading test concerning test loads, loading speed as well as shape, size and point of impact of test blocks in dependence on different configuration of gratings; h) revision of tightness t

20、ests for products for use with sheet floor coverings, membranes and liquid applied membranes. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus,

21、 Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Ki

BS EN 1253-1:2015EN 1253-1:2015 (E) 4 1 Scope This European Standard 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, irrespectiv

23、e of the material, for use in drainage systems requiring a trap with a depth of water seal of at least 50 mm (further: floor gullies). Although normally used to convey domestic wastewater, these floor gullies may convey other wastewater, e.g. industrial wastewater, provided there is no risk of damag

24、e to components or of injury to health. This European Standard does not apply to: linear drainage channels as specified in EN 1433, gully tops and manhole tops which are specified in EN 124, roof drains and floor gullies without trap as specified in EN 1253-2. 2 Normative references The following do

25、cuments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

43、s, shall form an integral part of the building. There shall be no movement possible between the body and the floor, which would impair the functioning of the installed gully. In areas where pressure testing of the pipe system is necessary floor gullies for use in the ground floor shall enable such t

44、est to be performed. The upper surfaces of frame and grating shall be flush. When in position, it shall not be possible for gratings and covers to be dislodged from the frame, but they shall be easy to be released for e.g. maintenance and cleaning. Traps shall be prevented, by design features such a

45、s fixings or weights, from uncontrolled floating or becoming displaced. Floor gullies and their components shall be resistant to normal actions of mechanical and thermal character. Floor gullies may be designed with or without side inlet. Floor gullies shall be delivered with installation instructio

46、ns. All pipe joints to and from the floor gully shall be designed to be watertight in accordance with EN 476. 4.1.2 Appearance Internal and external surfaces shall be free from sharp edges and imperfections which could impair functioning of the floor gully or give risk of injury. 4.1.3 Apertures in

47、gratings Apertures can be holes or slots of any shape and may also be formed between grating and frame. When measured in accordance with 5.1, the permissible aperture dimensions for gratings are given in Table 1. BS EN 1253-1:2015EN 1253-1:2015 (E) 9 Table 1 Apertures in gratings Class Dimensions of

49、lso be used with a maximum width of apertures up to 31 mm. bApertures of less than 4 mm width are permitted and shall not form part of the hydraulic tests. 4.1.4 Side inlets There are two types of floor gully with side inlets as follows: 1) Type I: side inlets either partially or totally below the water level; 2) Type II: side inlets completely above the water level. The positioning of side inlets shall be checked in accordance with 5.2. 4.1.5 Depth of water seal Floor gullies for wastewater shall provide a minimum depth of water seal H of 50 mm a
