ISFH CalTeC

ISFH CalTeC is accredited by the German Accreditation Body (DAkkS) as an independent calibration and testing laboratory. It is divided into four specialized departments offering the following accredited services:

  • Testing the performance and reliability of thermal energy converters and storage systems, in particular
    • Solar thermal systems and components in accordance with ISO 9806, EN 12975, EN 12976, EN 12977, SRCC 100
    • Air, brine and water/water heat pumps in accordance with EN 14511, EN 14825, EN 16147
  • Calibration of silicon solar cells, calibrated current-voltage characteristics and spectral responsivity measurements in accordance with IEC 60904
  • Testing of spectroradiometers with regard to the accuracy of spectral irradiance in accordance with CIE 250
  • Testing the reliability of absorber coatings in accordance with ISO 22975-3, photometric tests from the UV to mid-infrared range

The scope of services permitted under our flexible accreditation range and additional test standards can be found in the document below. Testing according to similar or equivalent standards can be offered upon request.

In addition, each department offers numerous non-accredited services for non-standardized testing and development-related investigations.
