wash basin with a width of ≤ 530 mm, intended for hand washing only 3.3 multi-layer wash basin wash basin consisting of two or more layers of material 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.



EN 14688:2006 (E) 8 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. When tested in accordance with 5.9, the flow rate of a single overflow shall not be less than the values given in Table 1.
