Test methods

From functional testing to molecular structure

In our DIN EN ISO/IEC 17025 accredited test laboratory, more than 80 engineers, scientists and laboratory technicians are employed on a laboratory area of 5000 square metres. With our highly qualified staff and our high-quality and comprehensive equipment pool, all test procedures relevant to practice are carried out promptly. Not only do we test thermoplastics, elastomers and thermosets in accordance with all the norms and standards customary in the industry, but we can also work out an individual and solution-oriented test programme for you according to your special requirements.

 

  • Equipped for all requirements

  • Testing of plastics with regard to

  • physical/chemical or mechanical properties

  • Investigation of the molecular structure or

  • Methods of non-destructive testing

  • Fast and confidential order processing
