6 Crockmeter tests
6.1 Preparation
Before the apparatus is prepared for crocking tests, you should have decided:
•
according to which standard the crocking test should be carried out
•
which friction finger set, friction material and/or friction medium if necessary
you will be using
•
on the number of double strokes
•
on the evaluation procedure
•
on the time between the friction stress and the evaluation of the friction lane
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.
6.2 Mounting the friction finger sets
To carry out crocking tests, at least one friction finger set and one weight are
needed. Some standards or test procedures require additional equipment and
auxiliary material.
For available options for crockmeter tests please refer to chapter 3.4
“Options for
crockmeter tests
” on page 10.
A guideline for selecting the suitable equipment according to the desired standards
can be found in the document
