Testing Device
As testing equipment (see figure), a flat, torsion-resistant plate of 600 mm width and 2000 mm length is used, the slope of which can be adjusted from 0 to 45° in the longitudinal direction.
The lifting speed of the drive produces an angular speed of the plate of 1° per second maximum, that is, at least 45 seconds are needed to pass through the total angle of 45°.
The lifting movement can be controlled by the testing personnel either continuously or in stages of 0.5°. An angle-measuring unit which is connected to the testing equipment indicates the angle of inclination of the plate with respect to the horizontal to 0.5° ± 0.2°.
Platforms are fitted to the longitudinal sides of the testing equipment for the safety of the testing personnel.[Extract from BGR 181 and GUV-R 181]
