cm3 / 50 cm2BÖHME TEST
Abrasion resistance is an essential performance requirement in commercial and
industrial floors. Floors can be exposed to quite aggressive actions from trucks and foot
traffic. The disc abrader conforming to the Böhme method consists of a rotating wheel
made of cast iron, 750 mm dia., with a defined test track to receive the abrasive material
(white corundum sand) and a no-vibration specimen holder with a two arms lever loading
device.
The test specimen is clamped with a holder and submitted to a test force of 294 +/-3 N.
After the abrasive is sprinkled on the disc, the disc starts to rotate with a constant speed
for a certain number of cycles according to Standards EN 1338. At the end of the test,
the abrasion effect is measured as the loss (A= cm3 / 50 cm2) in specimen thickness or
volume.
