The Hellma Calibration Laboratory

Accredited according to DIN EN ISO/IEC 17025

The Hellma calibration laboratory is accredited* by DAkkS according to DIN EN ISO/IEC 17025.

The DIN EN ISO / IEC 17025 standard requires a comprehensive QM system that seamlessly connects to other systems such as ISO 9001. By achieving this accreditation*, we demonstrate proof-of-expertise in the calibration activities for the optical measurement variable radiometry.

The accreditation* authorizes to issue internationally recognized DAkkS calibration certificates and is the key to the high quality of the measurements, the international comparability and confidence in the work of the calibration laboratory and the transparency of the results.

*) The accreditation is valid only for the scope listed in the annex of the accreditation certificate D-K-18752-01-00

The DAkkS* calibration certificate

The official document confirming traceability

With the DAkkS* calibration certificate issued by Hellma you prove traceability to a higher standard (NIST) as is required by the family of standards DIN EN ISO 9000 and DIN EN ISO/IEC 17025.The calibration certificates are thus an important document and metrological basis for measuring and test equipment monitoring in the context of quality management.

The 3 pillars of a DAkkS accredited* calibration laboratory:

  • Intact and well-maintained technical infrastructure
  • Proof of competence, experience and skills
  • Effective quality management system

Guaranteed traceability

In the Hellma Analytics calibration laboratory, which is accredited* according to DIN EN ISO/IEC 17025, we manufacture UV/Vis reference materials based on the regulatory codes issued by NIST (National Institute of Standards and Technology), ASTM (American Society for Testing and Materials) and Pharmacopeias (Ph. Eur., USP). All measurement results can be traced back to NIST (photometric accuracy) or to PTB (Physikalisch-Technische Bundesanstalt) (wavelength accuracy) standard reference materials. (photometric accuracy): NIST SRM® 930e, NIST SRM® 1930. Hellma 666S300; wavelength accuracy: Hellma 667005. 

*) The accreditation is valid only for the scope listed in the annex of the accreditation certificate D-K-18752-01-00
