The Chaplin Abrasion Tester
The Chaplin Abrasion Tester gives a guide to the abrasion
resistance
of concrete floors. It can also be used to test the effectiveness
of
surface treatments used to protect or up-grade sub-standard
floors.
The depth of wear in the concrete floor brought about by the
action
of 75mm diameter by 20mm wide hardened steel wheels, is used as a
guide
to the abrasion resistance.
The apparatus is suitable for compliance testing to
the requirements of BS 8204 : 1987 : Part 2.
The abrasion tester consists of three 75mm diameter hardened
steel
wheels mounted tangentially on a circular steel carrier plate.
The wheels
are fitted such that they are free to rotate but not castor.
The carrier plate is connected to a single phase electric motor
which runs at approximately 190 rpm. mounted in a steel
frame.
An umbilical cable connects the electric motor to a small
control
box, which monitors the number of revolutions executed by the
shaft
of the motor.
At the end of a preset number of revolutions, a counter in the
control
box switches off the power to the electric motor.
During testing, the abrasion tester is covered by an acoustic
baffle
which reduces the noise level generated by the machine.
Micro-switches fitted
at the bottom edge of this baffle switch off the electrical power
if the
baffle is lifted off the floor.
