Optical Calibration Laboratory conformance
The Kingfisher Optical Calibration Laboratory operates using ISO17025:2017 guidelines. Customer instruments are calibrated using equipment that is either self-referencing, or calibrated against an in-house primary standard, or fully traceable to internationally accepted standards via NMI, using documented procedures with established accuracy.
The laboratory became the the first commercial fiber optic calibration facility in Asia to gain traceable accreditation in 1993, when it gained NATA certification for calibration of optical power meters. It gained ILAC recognition in 2000. These lapsed some years later and in December 2018 the Laboratory formally reapplied to NATA for accreditation.
NATA, NMI and ILAC operate under inter-governmental agreements facilitated since 1875 by the BIPM, to ensure that SI unit measurements are accepted worldwide. These agreements tie together all the national standards laboratories such as NMI (Australia), NIST (USA), NPL (UK), METAS (Switzerland) etc.
ISO/IEC 17025: 2017
ISO/IEC 17025:2017 is the modern global standard for the technical & administrative competence of calibration laboratories. It also defines documentation and personnel requirements.
In conformance with this standard, our calibration certificates also do not show a "suggested recalibration period".
The standard replaces a number of older standards and guides including ISO/IEC Guide 25, EN45001 and ANSI/NCSL-Z540.
TIA-455-231, IEC-61315, FOTP-231: Calibration of fiber optic power meters
The laboratory calibration methods for optical power conform to this standard.
Since 1993, our laboratory has used the concepts embodied in this document, which came out later in 1995. For this early work, we acknowledge the valuable contribution made by the staff of Australia's National Measurement Institute (formerly the CSIRO National Measurement Laboratory).
