7.1 Preparation

Before the apparatus is prepared for scrub tests, you should have decided:
according to which standard the scrub test should be carried out

which friction set you will be using

if an even or a curved sample will be inserted

Up to 4 identical or different friction sets can be used at the same time, depending on the
friction material, the sample surface, the speed and the test load.
The highest possible test load is depending on the friction material, the sample surface and
the speed.
The provided delivered glass plate is used for application as well as with the modification
sets.
Generally, the scrub tester can be used with the glass plate, though it is recommended to
use the scrub tester with the sample tray for scrub tests.
The following needs to be considered:
the thickness of the sample will be reduced due to the maximal height of the tool holder (4)

no liquids must be used.
