Accredited testing

At Fraunhofer IGB, we ensure by established and standardized processes and procedures that the quality of our services and products meet the respective requirements. A quality management system guarantees that our accredited tests comply with DIN EN ISO / IEC 17025.


The accreditation of selected reference laboratories and test procedures of our analytics guarantees that our proprietary, in-house test methods and procedures are sufficiently validated and that the quality of our tests is assured even where no standardized methods are available.

The following analytical methods and test procedures are accredited according to DIN EN ISO/IEC 17025:

  • High-performance liquid chromatography (HPLC)
  • Ion chromatography (IC)
  • Gas chromatography (GC, GC/MS)
  • Atomic emission spectrometry (ICP-OES)
  • Electron spectroscopy for chemical analysis (ESCA/XPS)
  • In vitro cytotoxicity testing
  • In vitro phototoxicity testing

Accredited biocompatibility and phototoxicity testing

We perform tests for in vitro cytotoxicity according to DIN EN ISO 10993-5: 2009 using cell lines. Additionally, in vitro phototoxicity testing was included in our accreditation system in 2014. With our in-house methods we can investigate solutions and substances with respect to their phototoxic potential. The test method is in accordance with the OECD Guideline 432 and the INVITTOX Protocol no 121. The investigation of the potential photoactive substances is performed on our in-house designed three-dimensional skin model.

Certificates and QM manual

The accredited testings are certified on the certificate and in the appendix to the certificate. With our QM manual, we document our QM system in the reference laboratories and describe quality assurance measures and responsibilities.
