The testing laboratory of the Fraunhofer IBP in Holzkirchen is since 1999 accredited by the DAR (Deutscher Akkreditierungsrat) in accordance with DIN EN ISO/IEC 17025. The flexible accreditation certifies the high scientific competence and professional qualification of the testing laboratory. In particular it is therefore authorised - in addition to employing standard test methods - to develop new or modify and improve existing test methods.

IBP-Holzkirchen has been accredited for the following tests:

• Hygric characteristics and weathering resistance
    



Since moisture is a common cause for damage to building products and all weathering processes - biological, chemical or physical - require the presence of water, the behaviour of a building component depends crucially on its hygric characteristics.



• Hygric characteristics
• Pore space properties
• Hygrothermal dimensional stability characteristics
• Field tests



---



• Fresh and solid mortar properties
    



These tests are conducted mainly as a supplement to field tests to characterize the used mortars and plasters and to compare conventional plasters and mortars with newly developed ones.



• Fresh mortar properties
• Solid mortar properties
• Hygric properties



---



• Radiometric and photometric properties
    



Radiation tests including solar radiation tests and laboratory tests: Transmission, reflection, absorption, emission, total solar energy transmission. Measurements with grid-spectrometer or Fourier-interferometer on homogeneous specimens and measurements at natural sunlight on large and inhomogeneous specimens.



• Laboratory spectrometer tests
• Solar radiation tests in the outdoor testing area
