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:
- Performance and reliability testing of solar thermal systems and components in accordance with ISO 9806, EN 12975, EN 12976, EN 12977, and SRCC 100.
- Calibration of silicon solar cells, including calibrated current-voltage (I-V) characteristics and spectral responsivity measurements according to IEC 60904.
- Testing of spectral radiometers regarding the accuracy of spectral irradiance according to CIE 63.
- Reliability testing of absorber coatings according to ISO 22975-3, including photometric analysis from the UV to the 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.
- Scope of accreditation – Calibration Laboratory (German only)
- Scope of accreditation – Testing Laboratory (German only)
- Current Service Portfolio (German only)
