Helmet Surface Friction Tester

The Helmet Surface Friction Tester is a device used to evaluate the frictional properties of helmet surfaces. It measures how the helmet outer material interacts with different surfaces or materials, helping to assess slip resistance, abrasion, and overall surface durability under controlled conditions.

Application

The Helmet Surface Friction Tester evaluates the friction resistance of helmets. The helmet is pressed onto a movable fixture with a specified force. The fixture surface is covered with sandpaper of a standard-defined grit. The test helmet is then moved across the sandpaper at a controlled speed, allowing assessment of the helmet’s frictional performance.

Standards

Meets the requirements of ECE R22.05.

Technical Specifications

(1)The tester can perform friction tests on both protruding areas and flat surfaces of the helmet.

(2)Impact weight: 15 kg

(3)Free-fall height: 500 mm

(4)Load cell force: 400 N (40.8 kg)

(5)Release mechanism controlled by an electromagnet

(6)Sandpaper or shear blocks can be installed on the horizontal guide frame to perform linear friction with the helmet surface.

(7)Adjustable helmet mounting fixture

(8)Touchscreen control
