Reliable readings thanks to accredited test lab
As a leading manufacturer of light measurement technology, measurement quality takes top priority at Instrument Systems. To this end, we operate an accredited testing laboratory at our facilities in Munich and Berlin. All measuring instruments produced by us are subjected to a detailed quality check, and their results are documented in test certificates.
Internationally valid accreditation
Accreditation to DIN EN ISO / IEC 17025:2018 is carried out by DAkkS (German Accreditation Body). The latter is a full member of ILAC (International Laboratory Accreditation Cooperation), ensuring the international validity and recognition of the accreditation. The underlying standard lays down the requirements to be met by the test lab, whereby particular emphasis is placed on technical details, e.g. choice of test procedure, validation, metrological traceability and measurement uncertainty.
Quality assurance of testing laboratory and range of services
We undergo regular laboratory comparisons and independent tests within the framework of accreditation. Extensive training ensures the competence of our employees in the test lab and thus the consistently high quality of our measuring instruments.
Scope of accreditation:
Instrument Systems is accredited for a wide range of radiometric and photometric testing, e.g.:
- Colorimetry – tristimulus values X, Y, Z and color measurement values that can be derived therefrom by calculation (ISO 11664)
- Luminous flux and radiant power from 360 to 1100 nm
- Luminance and radiation density from 360 to 1100 nm
- Spectral irradiance from 200 to 2500 nm
- Luminous flux for LEDs according to CIE 127:2007
- Averaged LED Intensity: ILED-B to CIE 127:2007
A complete list of our range of services is attached to the accreditation certificate. We have compiled an overview of the standards and test methods used by us.
Traceability to reference standards for independently comparable measurement results
Our accredited test lab guarantees independent, reliable and comparable readings, directly traceable to the reference standards of the National Metrological Institute PTB (Germany) and NIST (USA) for any measuring instrument purchased. A direct comparison of your own measurement results is thus always possible, regardless of the specific metrological implementation and locations of measuring stations or production lines.
