Accredited Testing Laboratory

In 2002, the Czech Institute for Accreditation granted to Polymer Institute Brno the Certificate of Accreditation authorizing the use of the status of an accredited testing laboratory according to the standard ČSN EN ISO/IEC 17025.

Latest news:

In 2023, last re-accreditation was carried out and the list of tests in the scope of accreditation was expanded for the following tests:

  • Determination of strain hardening modulus (SHT) acc. to ČSN ISO 18488
  • Identification by FTIR method acc. to method PIB PP 43

A summary of services of the accredited testing laboratory is listed in the following promotional material:
