It shall be mounted on the end of a pendulum arm so that the sliding edge is (514 ± 6) mm from the axis of rotation. 5.2 A pendulum arm.
The mass, including the test foot, shall be (1,50 ± 0,03) kg. The centre of gravity shall be on the axis of the arm at a distance of (410 ± 5) mm from the axis of rotation. 5.3 Means for setting the support column of the equipment as vertical. 5.4 A base of sufficient mass to ensure the equipment remains stable during the test. 5.5 Means of raising and lowering the axis of suspension of the pendulum arm so that the slider can swing clear of the surface of the specimen, and be set to traverse a surface over a fixed length of (126 ± 1) mm.
A gauge as shown in Figure 2 shall be suitable. SIST EN 16837:2018

The mass of the pointer shall be not more than 85 g. 5.8 A circular scale (C scale) as described in Table A.1 and Figure A.1, calibrated for a nominal sliding length of 126 mm on a flat surface marked from 0 to 150 at intervals of five.
The combined mass of test foot shall be (32 ± 5) g.

This is the 0 reading. 6.2 The slider rubber The slider rubber shall be vulcanized or bonded onto the backing. The test foot shall be provided with a central pivoting axis which shall be mounted on the end of the pendulum arm in such a way that, when the arm is at the lowest point of its swing with the trailing edge of the slider rubber in contact with the test surface, the plane of the slider is angled at (26 ± 3)° to the horizontal. In this configuration the slider can turn about its axis without obstruction to follow the unevenness of the test surface as the pendulum swings. SIST EN 16837:2018
