4 Requirements
4.1Load resistance
When tested in accordance with 5.2, wall-hung wash basins shall not crack, be broken or show permanentdistortion.
4.2Draining of water
When tested in accordance with 5.3, all water shall drain away.4.3Resistance to temperature changes
When wash basins are tested in accordance with 5.4,they shall not show defects，such as cracks ordelamination which influences the intended use.
Experience has shown that wash basins made of glazed ceramics, stainless steel, enamelled steel and glasscomply with this requirement.
4.4Resistance to chemicals and staining agents
When used as intended, any functional surface shall be resistant to household chemicals and cleansingagents recommended by the manufacturer.
When tested in accordance with 5.5,wash basins shall not show any permanent surface deterioration, suchas 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 complywith 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 toplayer 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 theserequirements.
4.6Cleanability
When tested in accordance with 5.8,wash basins shall have smooth and readily cleansed non-absorbentfunctional surfaces which are free from acute internal corners which would be difficult to clean, i.e. surfacesintended to or likely to come into contact with water during use.
Experience has shown that wash basins manufactured from plastics materials,enamelled steelcast ironstainless steel, glazed ceramics and glass, designed and constructed without acute internal corners, satisfythis requirement.
4.7Protection against overflowing4.7.1 Wash basins with overflow
Every wash basin shall be protected against overflowing.
In two-bowl wash basins, it is permitted to have only one overflow,if the overflowing from one bowl to theother is ensured.
4.7.2Wash basins without overflow
A wash basin with a non-closable outlet or a floor gully may also be used as a protection against overflowing.ln this case the wash basin is considered to be class CL oo.
4.8 Durability
Products conforming with the requirements of 4.1 to 4.7 are deemed to be durable.
5 Test methods
5.1General
All tests may be carried out on the same sample wash basin.
5.2 Load resistance
Install the wash basin to be tested in a horizontal position in accordance with the manufacturer’sinstructions onto smooth surface(s) with a layer of mortar or other facing material used for pointingbetween the back of wash basin and the smooth surface.
Gradually apply a force of (1,50 ± 0,01)kN on top of a wooden beam with a cross section of100 mm x 100 mm positioned in accordance with Figure 6.Allow the force to remain in position for aperiod of 1 h.
5.3Draining of water
– Install the wash basin horizontally in accordance with the manufacturers installation instructions. The
wash basin shall be cleaned with cleansing agents recommended by the manufacturer and afterwardsshall be rubbed dry.
一Pour not less than 1 l water evenly around the upper inside edge of the bow(s).
Visually examine whether the water has drained to the waste outlet hole(s). Water remaining due tosurface tension is permitted.
5.4Resistance to temperature changes5.4.1 Test apparatus
5.4.1.1 A hot water supply, capable of delivering water at a temperature of (70 ± 2)C at the outlet of thedischarge pipe.
5.4.1.2A cold water supply, capable of delivering water at a temperature of (15±2)C at the outlet ofthe discharge pipe.
5.4.1.3 A discharge pipe with an internal diameter of 10 mm for delivering the hot and the cold water.5.4.1.4 Means of supporting the wash basin to be tested in a horizontal position.
No stress shall be exerted on the wash basin.
5.4.1.5 A thermometer, capable of measuring temperatures between 0 °C and 100 °C with an accuracyof± 1 C at the measured temperature.
5.4.1.6 flow meter, capable of measuring a flow rate of(0,1 ±0,01)l/s.BS EN 14688 pdf free download.
