DIN EN ISO 12947-2 Abrasion (accredited)

Our test laboratory performs testing according to DIN EN ISO 12947-2 under accredited conditions. This international standard specifies a method for determining the abrasion resistance of textile materials using the Martindale method, with particular focus on the number of abrasion cycles required to cause breakthrough (end-point determination).

Test principle and procedure

Testing is carried out using a Martindale abrasion tester. Circular specimens are subjected to a defined contact pressure against a standardized abrasive material (e.g., standard wool fabric or an alternative abrasive). The specimen moves along a Lissajous pattern, resulting in uniform, multidirectional stress that closely simulates real-use conditions.

Key test parameters include:

• contact pressure (e.g., 9 kPa or 12 kPa depending on the application)

• type of abrasive material (standard fabric or specific counter-materials)

• number of abrasion cycles

• conditioning of specimens under standard climate conditions

During the test, specimens are inspected at defined intervals. The end point is reached when a specified damage criterion occurs, typically:

• breakthrough (hole formation)

• yarn breakage in woven fabrics

• visible structural destruction of the surface

The number of cycles to failure is recorded and represents the key parameter for evaluating abrasion resistance and wear durability.

Application in the automotive industry

This method is also applied to automotive interior materials, for example in a comparable form within VDA 230-227.
