Foreword
This European Standard 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by endorsement, at the latest by July 2002, and conflicting national standards shall be withdrawn at the latest by
July 2002.
Together with Parts 2 and 3 of this standard, this European Standard supersedes EN 274:1992, EN 329:1994 and
EN 411:1995.
The other parts of the European Standard contain the necessary statements on testing and quality control of waste
fittings for sanitary appliances.
Annex A is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
1 Scope
This standard specifies the dimensional, performance, materials and marking requirements for waste outlets, traps
and overflows for kitchen sinks, shower trays, wash basins, bidets and baths which are connected to gravity
drainage systems, whatever the purpose of the building.
This standard does not specify requirements for waste outlets, traps and overflows which are integral with sanitary
appliances.
NOTE  All figures in this standard are diagrammatic only.
This standard does not cover the possible effect of aggressive drain cleaning materials on products.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
waste outlet
fitting through which the water is evacuated from the sanitary appliance, which can be sealed by means of a flap or
plug and can be equipped with a fixed or a removable grille
3.2
overflow
fitting which allows the evacuation of excess water when a sanitary appliance is filled above a certain level
3.3
trap
fitting which provides a hydraulic seal between the waste outlet and the discharge pipe in order to prevent the entry
of foul air from the discharge pipe into the building, without obstructing the discharge of the wastewater
4 Requirements
4.1 General
Waste outlets, traps and overflows enable the functioning of sanitary appliances. They shall be capable of being
connected to drainage pipework systems in accordance with EN 12056-1 and EN 12056-2.
4.2 Appearance of surfaces
When viewed without magnification, the internal and external surfaces of the waste fittings shall be smooth, free
from grooving, blistering or any other surface defects likely to impair their functioning.
The appearance of visible electrodeposited NiCr coatings shall comply with EN 248.
4.3 Materials
Waste outlets and traps shall be manufactured from materials which withstand intermittent contact with domestic
waste water with a temperature range from (20 ± 5) °C to 95 °C when tested in accordance with clause 3 of

2
EN 274-2:2002. Waste outlets and traps made of only metallic materials are deemed to satisfy this requirement.
The materials used shall be such that the finished products meet the requirements of this standard. It is the
responsibility of the manufacturer of the waste fittings to employ materials which are fit for this purpose. This
requirement does not cover the use of aggressive drain cleaning materials. The use of such materials is beyond the
scope of this standard.
4.4 Design
4.4.1 Waste outlets
Waste outlets may be manufactured in one piece or may comprise various pieces joined together mechanically,
either with or without an overflow. They can include a trap.
Waste outlets not fitted with a trap shall have a threaded or a plain outlet dimensioned as given in Table 1.
Waste outlets can be fitted with a fixed or removable gri
