This European Standard shall be given the status of a national standard, either by pub
13、lication of an identical text or by endorsement, at the latest by August 2017, and conflicting national standards shall be withdrawn at the latest by August 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be he
14、ld responsible for identifying any or all such patent rights. This document supersedes EN 1253-5:2003. This is the fifth part in EN 1253, a series of standards relating to different types of floor gullies, roof drains and access covers for drainage systems inside buildings. The EN 1253 series under
15、the main title Gullies for buildings actually consists of the following parts: Part 1: Trapped floor gullies with a 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 clos
16、ure. Since the latest versions of EN 1253-5 the most significant technical changes are the following: a) introduction of the new standards on trapped floor gullies with a depth of water seal of at least 50 mm (EN 1253-1) and evaluation of conformity (EN 1253-3); b) amendment of scope, classification
17、, requirements as well as methods of marking. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Form
18、er Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

19、E) 4 1 Scope This European Standard specifies requirements for the design, construction, performance, application and marking as well as test methods of factory made gullies with a light liquid closure for buildings. Light liquid closures for buildings are applied to avoid uncontrolled discharge of
20、light liquids into drainage systems in case of emergency. This European Standard does not apply to installations for separation of light liquids covered by EN 858-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable
21、 for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

22、3-3, Gullies for buildings - Part 3: Evaluation of conformity 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1253-1:2015 and the following apply. 3.1 gully with a light liquid closure trapped floor gully with closure device which prevents the light l
23、iquid from entering the drainage system 3.2 light liquid closure device which automatically closes the gully outlet when a certain level of light liquid is present 3.3 light liquid liquid with a density not greater than 0,95 g/cm3which is actually or practically insoluble in water and unsaponifiable
24、 Note 1 to entry: Such liquids are, e.g. petrol, diesel fuel, fuel oil. 4 Types Type A: Gully with an integrated light liquid closure with a flow rate in accordance with Table 1 for the unlimited use in gravity drainage systems. Type B: Gully with light liquid closure which is incorporated as an acc
25、essory, with a minimum flow rate given in Table 1, which may be reduced up to 30 % for use in gravity drainage systems. 5 Materials All material in contact with the light liquid and the wastewater shall be resistant to light liquids and to wastewater. BS EN 1253-5:2017EN 1253-5:2017 (E) 5 6 Requirem
26、ents 6.1 General A gully with light liquid closure shall fulfil all requirements given in EN 1253-1, except for flow rates, and the following requirements given in 6.2 to 6.6. The manufacturer shall supply all the appropriate information concerning the use of the trapped gully with a light liquid cl
27、osure, e.g. handling, transport, temporary storage and instructions for installation, operation and maintenance. 6.2 Inflow The inflow shall be through the grating on the top of the gully. Inlets under the grating and behind the light liquid closure are not allowed. The light liquid closure shall be
28、 sufficiently protected against dust, dirt, inflow and others which could impair functioning. 6.3 Security height When the light liquid closure has closed the gully, there shall be a security distance between the sealing and the separating line between water and light liquid of 30 mm.

33、orresponding to that indicated by the manufacturer 0,015 g/cm3at 12 C, slowly (0,1 l/s) into the gully, until the closure device closes, but at least up to the top of the grating. Place a container under the pipe outlet, and determine after 1 h the amount of water and light liquid in the container.
34、7.3 Security height When the closure device has closed (see 7.2), measure by suitable methods the distance between the sealing and the separating line between water and light liquid. 8 Marking Gullies with a light liquid closure device and their components shall bear the following clear and durable
35、markings, for example, cast on, by engraving, painting, stamping or labelling (including electronic recognition labelling) as indicated in Table 2: a) EN 1253-5; b) name and/or mark of the manufacturer; c) period of manufacture (coded or not); d) identification of independent certification body, whe
