Helmet Surface Friction Testing Machine
Purpose
The Helmet Surface Friction Tester presses a helmet onto a movable fixture with a certain force. The surface of the fixture is attached with sandpaper of the grain size specified in the standard. Then, the test helmet is moved across the surface of the sandpaper at a certain speed, so as to evaluate the abrasion - resistance performance of the helmet.
Applicable Standard
ECE R22.05
