Scrub test

6.1 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.

6.1.1 Available friction sets

Friction set for ISO 11998
Friction set for ASTM D4213
Standard specification: weight – 450 g (0.99 lbs), bearing
surface – 95 x 75 mm (3.74" x 2.95"). The bearing surface has
been halved and the weight reduced to half.
Friction set for ASTM D4828
Standard specification: weight – 1000 g (2.2 lbs), bearing
surface – 95 x 76 mm (3.74" x 2.99"). The bearing surface has
been halved and the weight reduced to half.
Friction set for ASTM D3450
Standard specification: weight – 1500 g (3.31 lbs), bearing
surface – 95 x 76 mm (3.74" x 2.99").The bearing surface has
been halved and the weight reduced to half.
Friction set for ASTM D2486
Universal holder
The universal holder is not subject to any standards. It can be
equipped with any abrasive media. The test load will be
determined by the operator in 50 g (0.11 lbs) steps.
