Advanced Abrasion Resistance Tester

Darmstadt method determining the abrasion resistance of motorcycle protective clothing

The test method to determine the impact abrasion resistance of motorcycle protective clothing, developed by the Institute of Automative Engineering at the Technische Universität Darmstadt, is an essential part of the European Standard EN17092-1, which became applicable in 2018. The requirements concerning motorcycle protective clothing of certain protective classes posed in the European Standards EN17092-2 to EN17092-6 will be analyzed with test methods described in EN17092-1.

Technical Data

  • Road surface: asphalt or cement concrete
  • Initial speed: 60 km/h – 100 km/h
  • Diameter of the sample’s motion path: 900 mm
  • Number of samples per test (p.r.n. in different clamping directions): 3
  • Diameter of samples: 125 mm
  • Diameter of contact surface between samples and “road”: 47..48 mm

Evaluation, results:

  • slip period
  • slip distance
  • hole formation
  • mean coefficent of friction
  • relative loss of mass
  • (temperature measurement retrofittable)

Relevance for research

  • Crash simulation of a standard 75kg motorcycle rider on different road surfaces with variable initial speed
  • Determining hole formation, tear, friction and wear resistance of leather and textile materials with various coats
  • Order verification for institutes for materials research, manufacturers of (motorcycle) protective clothing as well as (motorcycle) specialist journals (comparative tests)

Advanced Abrasion Resistance Tester (AART)

The EN17092-1 includes a description of the Darmstadt method determining the impact abrasion resistance. The Advanced Abrasion Resistance Tester (AART) is a testing device developed by the Institute of Automative Engineering, and it meets these requirements.

Manufacturing and sale of the AART

For Manufacturing and sale of the AART, the Technische Universität Darmstadt have entered an exclusive concession agreement with the spin-off company Testcenter Rhein-Main (TRM) GmbH that is valid worldwide. TRM GmbH will gladly provide further information on this testing device and submit an individual offer for you upon request. The Institute of Automative Engineering and TRM GmbH also cooperate in the sphere of Testing in order to bridge potential delivery times. Therefore, from now on we can offer you a testing of materials, dependent on your requirements.
