  • Test type:

    scratch resistance, damage resistance

  • Test material:


  • Operating mode:


  • Technology:



A continuous load is used for calculation of scratch resistance. The test piece is placed on a mobile base, and a needle is loaded onto its surface. The base is then made to move with the continuous load, until scratching (film peeling) begins. The load can be calculated by using the distance to failure point.
Different needle diameters and materials can be used for appropriate testing of most surfaces. Scratch hardness can be measured by using a fixed load instead of a continuous one. This system does not have an output module.
