20、 (EN 1253-2:2015) has been prepared by Technical Committee CEN/TC 165 “Waste water 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 endorsement, at the latest by July 2015
21、and conflicting national standards shall be withdrawn at the latest by July 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This
22、 document, together with EN 1253-1:2015, supersedes EN 1253-1:2003 and EN 1253-2:2003. This is the second part in 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 buildin
23、gs will actually consist of the following parts: Part 1: Trapped floor gullies with a depth of 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 versi
24、ons of EN 1253-1 and EN 1253-2 the most significant technical changes are the following: a) reduction of scope on roof outlets and floor gullies without trap including parapet and emergency drains for use in gravity and siphonic drainage systems; b) more definitive description of products; c) modifi
25、cation of terms and definitions; d) precision in definition of places of installation; e) consideration of liquid applied membranes as connecting components; f) precision of test conditions for flow rate testing for different types of products; g) revision of loading test concerning test loads, load
26、ing speed as well as shape, size and point of impact of test blocks in dependence on different configuration of gratings; h) introduction of classification of products concerning their temperature cycling behavior according to number of hot/cold water cycles. According to the CEN-CENELEC Internal Re
27、gulations, the national standards organizations 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, Germany, Greece, Hungary, Iceland, Ireland,
28、 Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 1253-2:2015-03 EN 1253-2:2015 (E) 4 1 Scope This European Standard classifies roof drains and floor gullies without trap
29、 for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking as well as test methods of factory made roof drains and floor gullies without trap (further: floor gullies) for buildings, irrespective of the materia
30、l for use in drainage systems. Although normally used to convey rainwater and wastewater, these roof drains and floor gullies without trap may convey other wastewater provided there is no risk of damage to components or of injury to health. This European Standard does not apply to trapped floor gull
31、ies with a depth of water seal of at least 50 mm as specified in EN 1253-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
