3 Terms and definitions
For the purposes of this standard the terms and definitions given in ISO 2424 apply.
4 Principle
A textile floor covering is submitted for a prescribed number of cycles to the action of three castors which
produce an eccentric turning motion.
At the end of each test:
- the change in appearance in accordance with EN 1471 is assessed after 5 000 cycles and 25 000 cycles
(Test A);
- the change in colour by means of grey scales is assessed after 750 cycles (Test B);
- the extent of deterioration of the specimen is assessed after 10 000 or 25 000 cycles
(Test C).
5 Test apparatus (Figure 1)
5.1 Circular, rotating testing platform, of diameter (800 ± 5) mm on which the specimen support plate is
mounted. The rotation speed of the testing platform shall be (19 ± 1) r/min and the direction of rotation shall
reverse at (180 + 20) s intervals. The stop time between reversals shall be (5 ± 1) s.
5.2 Castor assembly, comprising a vertical shaft set in a bearing and a plate, R, on which the castors are
mounted. This castor assembly is offset at a distance of (198 ± 1) mm from the centre of the testing platform.
The three castors (5.3) are arranged concentrically at 120 intervals around the centre of the plate and at a
distance of (130 ± 1) mm from the centre of the plate. They are free to rotate so that they follow the rotation of
the castor assembly. The rotation speed of the castor assembly shall be (50 ± 1) r/min.
The castor assembly when loaded has a mass of (90 ± 1) kg that is divided equally over the three castors.
The distance under load between the castor assembly plate R and the load/drive plate C (castor plate clearance)
shall be more than 3 mm at the point of measurement (see Figure 1).
NOTE 1 The area of stress produced on the test specimen is determined by the distance between the axes of revolution of
the castor chair assembly and of the testing platform and also by the distance of the castors from the centre of the plate. The
stressed area is approximately 0,3 m
NOTE 2 The relationship between the rotation speed of the testing platform and that of the castor assembly causes a sharp
reverse movement of the castors near the edges of the stressed area.
5.3 Castor set, comprising three castors as illustrated in Figure 2 with the following dimensions:
diameter of castors (50 2) mm
width of castors : (20 2) mm
radius of curvature of castor tread: (130 5) mm
crank distance: (32 2) mm
The distance between any two castor mountings shall be (225 5) mm.
The castors shall be Type H in accordance with EN 12529:1998. The castor treads shall be made from
polyamide having hardness between 90 and 100 Shore scale A units and shall be replaced after every 2 million
cycles of the testing platform, or earlier if necessary.
5.4 Lifting device, to raise the castor assembly above the testing platform when the apparatus is stationary.
5.5 Cycle counter, for setting the number of cycles of the testing platform.
5.6 Suction device, with a flow rate of 25 to 30 l/s mounted over the entire width of the stressed part of the
specimen, the height of this device being adjustable.
5.7 Specimen support, comprising a circular sheet of rigid plastic (e.g. polymethylmethacrylate) of
(7 2) mm thickness and diameter (800 5) mm. The support is placed on the testing platform with the holes in
the support locating on studs on the testing platform to prevent slippage.
5.8 Metal clamping ring, of height (10 2) mm, external diameter (700 5) mm and internal
diameter (680 5) mm, to hold loose laid tiles, or carpet over an underlay, in position during the test.
5.9 Brush vacuum cleaner, with rotating brush, driven by an independent motor.
6 Sampling and preparation of specimens
6.1 Sample the material to be tested according to ISO 1957.
6.2 Prepare the specimens as follows.
6.2.1 Test A
Cut either three semi-circles or six quadrants of radius (350 3) mm ensuring that the edges are parallel to
and/or at right angles to the direction of manufacture. Cut also a reference specimen with dimensions of
(200 2) mm x (200 2) mm. In all cases mark the specimens with the direction of manufacture.
If testing only one textile floor covering a third specimen is required to fill the gap left by removal of the 5 000
cycle specimen (see 8.4.2).
6.2.2 Test B
If possible, test different batches/colour ways during each test.
Cut either one semi-circle or one quadrant of radius (350 3) mm from each batch/colour. Cut also a reference
specimen, with dimensions of (200 2 ) mm by (200 2) mm.
