The preliminary work was done by Working Group WG 1 “General requirements for pipes”. The responsible German body
5、 involved in its preparation was the Normenausschuss Wasserwesen (Water Practice Standards Committee), Working Committee NA 119-05-09 AA Allgemeine Anforderungen an Rohre, Rohrverbindungen etc. fr Abwasserkanle und -leitungen.

Amendments This standard differs from DIN EN 476:1997-08, DIN EN 773:1999-06 and DIN EN 1293:1999-06 as follows: a) the contents of DIN EN 773:1999-06 and DIN EN 1293:1999-06 have been incorporated and thus, DIN EN 476:1997-08 has been restructured; b) the definition of the nominal s
7、ize, DN, has been extended to include pipes with profiled external surface and outside smooth spigot jointing dimensions; c) for the tightness testing of pipes and fittings, the test duration has been specified; d) the former Clause 10 “Quality control” has been deleted.

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of an identical text or by endorsement, at the latest by July 2011, and conflicting national standards shall be withdrawn at the latest by July 2011. Attention is drawn to the possibility that some
24、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 document supersedes EN 476:1997, EN 773:1999 and EN 1293:1999. The specifications of this standard have been based on the require
25、ments for wastewater systems specified in EN 752 and EN 12056. This document is the result of merging EN 476, EN 773 and EN 1293. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria,

27、EN 476:2011-04 EN 476:2011 (E) 5 1 Scope This European Standard specifies general requirements for components inside and outside buildings (see EN 12056-1) such as pipes, fittings and manholes with their respective joints intended for use in discharge pipes, drains and sewers which operate as gravit
28、y systems allowing for a maximum pressure of 40 kPa. It also specifies general requirements for components used in hydraulically and pneumatically pressurised discharge pipes, drains and sewers. It provides basic specifications to be respected in material related product standards for these applicat
29、ions. It is not applicable for the direct evaluation of products. It is applicable as a reference for drawing up a product specification, if there is no product standard available. NOTE Where the term “inside buildings“ is used in the context of components fixed inside buildings, it also includes di
30、scharge pipes and fittings fixed on external surfaces of buildings. This European Standard covers components to be used in conveying in a satisfactory manner: domestic wastewater; rainwater and surface water; and other waste waters acceptable for discharge into the system (e.g. industrial wastewater
31、). This European Standard applies to components of circular and other cross sections. This European Standard applies equally to components which are factory-made and to those constructed on site, where applicable. This European Standard does not apply to components used for trenchless construction a
32、ccording to EN 14457 and for components used for renovation of drains and sewers according to EN 13380. 2 Normative references The following referenced documents are indispensable for the application of this document.
