Advanced Abrasion Resistance Tester (AART)

Darmstadt method for determine the abrasion resistance

The test method developed for the determination of the impact abrasion resistance of protective clothing (special motorcycle protective clothing), elaborated by the Institute of Automotive Engineering at Technische Universität Darmstadt, is an essential component of the future European Standard EN17092-1. The requirements of the EN series EN17092-2 to EN17092-6 for motorcycle protective clothing of appropriate protection classes are examined by the test procedures described in EN17092-1. The test conditions of the Darmstadt method for impact abrasion resistance determination are also included in EN17092-1.

The "Advanced Abrasion Resistance Tester" (AART)

In order to investigate the requirements for motorcycle protective clothing in accordance with EN17092-2 to EN17092-6 by means of the Darmstadt method, TRM GmbH offers you the CE-certified testing device “AART”. AART provides a reliable determination of the impact abrasion resistance according to the new Darmstadt method (EN17092-1). The AART tester offered by TRM GmbH fulfills the test requirements set out in EN17092-1. It also offers additional test functions (for example, higher surface pressure, higher mass inertia). It simulates the fall of an average driver on a realistic road surface and subsequent slipping until stopping. Different starting velocities, driving masses and mass inertia are possible.

For each test, the AART tester automatically ensures an immediate analysis of the covered slip path and the friction coefficients. The use of a concrete tile as a road surface substitute provides realistic (friction) conditions. The appropriate design of the "AART" testing device allows to test three identical material samples in one test operation.

 

  • Testing the impact abrasion resistance of motorcycle protective clothing in accordance with the new European Standard EN17092-1
  • In-depth investigation of the requirements according to EN17092-2 to EN17092-6 according to the Darmstadt method
  • CE certified
  • Conforming to standards
  • In cooperation with FZD (Prof. Dr. rer. nat. H. Winner), the TU Darmstadt is constantly developing and incorporating current research results

Tests covered by „AART“

Based on a fall of an average motorcyclist the determination of impact abrasion resistance according to the Darmstadt method in EN 17092-1 is simulated by an impact on concrete tile as a substitute for average road surfaces until stopping. In addition, a variation of testing parameters above the required range is possible.

 

  • Simulated body weight 75 kg (EN17092-1) and higher
  • Simulated body high 1.75 m (EN17092-1)
  • Surface pressure according to (EN17092-1) also variable
  • Mass inertia according to (EN17092-1) also variable
  • Fall height according to (EN17092-1) and variable
  • Three identical material samples per test
  • Start velocity according to (EN17092-1) also variable
  • Realistic roadway (friction) conditions by using a concrete road tile
  • Direct output of slide path
  • Direct output of friction coefficient

Cooperation with TU Darmstadt

In August 2017, TRM GmbH signed a license agreement with TU Darmstadt (worldwide exclusive license) for the production and distribution of the AART tester. After the revision of the design, the CE certification and the preparation of the machine documentation, production was started in the first quarter of 2018 and the first machines were delivered.

 

We are now able to provide you with an individual quotation. For the delivery of an AART test device, which is produced in single production, please expect about six months delivery time. In order to compensate the delivery time, we can offer to carry out your testings in cooperation with the Institute of Automotive Engineering (FZD) of the TU Darmstadt at favorable conditions starting at the date of your order.

 

Please contact Albert Luft M.Sc. to get an individual quotation.
