In two-bowl wash basins, it is permitted to have only one overflow, if the overflowing from one bowl to the other is ensured. 4.7.2 Wash basins without overflow A wash basin with a non-closable outlet or a floor gully may also be used as a protection against overflowing. In this case the wash basin is considered to be class CL 00. 4.8 Durability Products conforming with the requirements of 4.1 to 4.7 are deemed to be durable. 5 Test methods 5.1 General 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's instructions onto smooth surface(s) with a layer of mortar or other facing material used for pointing between 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 of 100 mm x 100 mm positioned in accordance with Figure 6. Allow the force to remain in position for a period of 1 h. SIST EN 14688:2015

It incorporates a synthetic flexible open cell foam disc of 75 mm diameter and 15 mm thickness. It is driven by means of a square axle which loosely fits into the device. Any rotating device having a mass of (1 000 ± 50) g can be used. 5.5.1.5 12 h-alumina (suspension of aluminium oxide (Al2O3) in water)1).

Clean the test area thoroughly with hot soapy water then dry with a clean dry cloth. c) At each test area, deposit a drop of the test solution. Cover the drop with a watch glass concave side downwards. The drop size shall be determined in order to be completely covered by the watch glass. Allow the selected chemical to act for a period of (2 ± 0,25) h at (23 ± 5) °C protected from sunlight. d) Thoroughly rinse the test area with deionized water and check for adverse changes in appearances by visual examination. If deterioration exists, dip the foam disc in deionized water and place it on the surface to be tested. Rotate the cleaning device at a speed of 60 min−1. Clean for 30 revolutions. e) Rinse with deionized water and visually examine the test area. If deterioration persists, repeat the cleaning process with the 12 h-alumina and re-examine the test area.

The height of this axis shall be adjustable so that the arm is exactly horizontal when the scratching point rests on the test specimen. 5.6.1.4 Means of applying a defined force (C). 5.6.1.5 Diamond scratching point (D), cone-shaped, the axis of which is perpendicular to the sample surface and which has an angle of (45 ± 0,5)° at the top. The point of the cone shall be hemispherical with a radius of (0,09 ± 0,001) mm. Its geometrical regularity shall be verified and its profile measured on a complete rotation of 360°. The point shall be rejected, if any irregularity of the curvature above ± 0,001 mm is measured. All diamond points shall be rechecked after each 1 000 tests to confirm geometry. 5.6.1.6 Microscope or similar measuring device capable of measuring to an accuracy of 5
5.6.2 Test specimen Use a test specimen cut from the bottom of wash basin (see Figure 9). Test specimens shall be flat. When the test specimen cannot be cut from a wash basin, specially prepared specimens can be used provided the top functional layer is of the same thickness as that in a wash basin to be tested. The thickness of the top layer shall be measured in accordance with 5.6.3. The test specimen shall be preconditioned at a temperature of (23 ± 2) °C and relative humidity of (50 ± 5) % for 24 h. When using a microscope, pre-coat the test specimen with an ink of a contrasting colour. SIST EN 14688:2015

Figure 9 — Test specimen 5.6.3 Procedure — Adjust the height of the arm (B) so that it is horizontal when the diamond point rests on the test specimen. Place the arm (B) in a vertical position. Fix the test specimen with the locking disc (E) and secure it correctly to avoid any slipping. Lower the arm (B) and place the diamond point in contact with the test specimen taking care to avoid any impact. — Apply a force of (10 ± 0,1) N. — Start rotating the turntable in order to produce a scratch of 3 cm to 4 cm long. Measure the width of the scratch and calculate its depth as 50 % of the width of the scratch. Measure the thickness of the top layer in the middle of the four sides and calculate the average. 5.7 Resistance to abrasion 5.7.1 Principle The test measures the ability of the top layer of the multi-layer wash basin to resist abrasion through to the sub-layer. Abrasion is produced by rotating a test specimen in contact with a pair of loaded cylindrical wheels covered with abrasive paper. 5.7.2 Test apparatus and materials Test machine2) as specified in ISO 9352: 5.7.2.1 Calibration plates of rolled zinc sheet having a thickness of (0,8 ± 0,1) mm and a Brinell hardness of (48 ± 2) BHN when tested in accordance with EN ISO 6506-1, except that the ball diameter shall be 5 mm and the force 360 N.
