3Terms and definitions
For the purposes of this document, the following terms and definitions apply.3.1
wash basin
sanitary appliance primarily intended for washing the upper parts of the body, with one or more bowls, eachwith a waste outlet hole, with or without overflow and with or without taphole(s)
Note 1 to entry: The various types of wash basins are differentiated by the methods of mounting. The main types aregiven in the definitions that follow.
3.1.1
wall-hung wash basin
wash basin attached directly to a wall
Note 1 to entry:See Figures 1 and 2.
3.1.2
bracket-mounted wash basin
wash basin supported on brackets which are fixed to a wall
Note 1 to entry: See Figure 3.
3.1.4
vanity wash basin
wash basin installed into a vanity top
Note 1 to entry: See Figure 5.
Note 2 to entry: The bowl(s) may be mounted in different ways:
a) the rim of the wash basin rests on the vanity top (inset wash basin);
b) the front of the basin protrudes beyond the front edge of the vanity top (semi-recessed wash basin);
c) the rim of the wash basin butts against the underside of the vanity top (wash basin mounted beneath a vanity top);
d) the bottom of the wash basin rests on the vanity top (vessel wash basin).
4 Requirements
4.1 Load resistance
When tested in accordance with 5.2, wall-hung wash basins shall not crack, be broken or show permanent distortion.
4.2 Draining of water
When tested in accordance with 5.3, all water shall drain away.
4.3 Resistance to temperature changes
When wash basins are tested in accordance with 5.4, they shall not show defects, such as cracks or delamination which influences the intended use.
Experience has shown that wash basins made of glazed ceramics, stainless steel, enamelled steel and glass comply with this requirement.
4.4 Resistance to chemicals and staining agents
When used as intended, any functional surface shall be resistant to household chemicals and cleansing agents recommended by the manufacturer.
When tested in accordance with 5.5, wash basins shall not show any permanent surface deterioration, such as stains or deterioration not removable with water or abrasive agent.
Experience has shown that wash basins made of glazed ceramics, stainless steel and enamelled steel comply with this requirement.
4.5 Surface stability
This requirement is applicable only to multi-layer wash basins to ensure the stability of the top layer.
When tested in accordance with 5.6, any scratch shall not exceed 0,1 mm and/or the total depth of the top layer whichever is the least.
When tested in accordance with 5.7, the top layer of the test specimen shall not be abraded through.
Experience has shown that wash basins made of glazed ceramics and enamelled steel comply with these requirements.
4.6 Cleanability
When tested in accordance with 5.8, wash basins shall have smooth and readily cleansed non-absorbent functional surfaces which are free from acute internal corners which would be difficult to clean, i.e. surfaces intended to or likely to come into contact with water during use.
Experience has shown that wash basins manufactured from plastics materials, enamelled steel/cast iron,stainless steel, glazed ceramics and glass, designed and constructed without acute internal corners, satisfy this requirement.
4.7 Protection against overflowing
4.7.1 Wash basins with overflow
Every wash basin shall be protected against overflowing.
