15、3 European foreword This document (EN 1253-5:2017) has been prepared by Technical Committee CEN/TC 165 “Wastewater engineering”, the secretariat of 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 endorsem
16、ent, at the latest by August 2017, and conflicting national standards shall be withdrawn at the latest by August 2017.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 held responsible for identifying any or all su
17、ch 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 the main title Gullies for buildings actuall
18、y 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 closure. Since the latest versions of EN 1253-5
19、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, requirements as well as methods of marking
20、. 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, Former Yugoslav Republic of Macedonia, France, G
21、ermany, 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. DIN EN 1253-5:2017-05 EN 1253-5:2017 (E) 4 1 Scope This European Standard spe
22、cifies 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 light liquids into drainage systems in
23、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 for its application. For dated referen
24、ces, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、aluation 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 liquid from entering the drainage system
26、 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 Note 1 to entry: Such liquids are, e.g
27、. 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 accessory, with a minimum flow rate given
28、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. DIN EN 1253-5:2017-05 EN 1253-5:2017 (E) 5 6 Requirements 6.1 General A gully with ligh
29、t 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 closure, e.g. handling, transport, t
30、emporary 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 sufficiently protected against du
31、st, 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.
