What is ISO17025?

Kingfisher Optical Calibration Laboratory Certificates Conform to ISO 17025

ISO/IEC 17025 is a recently introduced standard from the International Organization for Standardization and the International Electrotechnical Commission. "ISO17025", as it has become known, replaces a number of older standards and guides including ISO/IEC Guide 25, EN45001 and ANSI/NCSL-Z540.

It is a global standard for the technical competence of calibration laboratories. In addition to establishing quality system, documentation and personnel requirements, it directs calibration labs to:

• Analyze the uncertainty of each measurement
• Incorporate the uncertainty into the calibration procedure
• Provide the uncertainties with the calibration certificate and results
  

Reporting the uncertainty qualifies the accuracy of the measurement and aids understanding when results from different labs are compared. The ratio of specification-to-calibration uncertainty is one way that users gauge their confidence in a product's performance.

ISO17025 is the single most important metrology standard for measurement products. Nearly all national standards bodies and accreditation agencies around the world have adopted it. A growing number of companies require it and some industries have even incorporated it into sector-specific standards (for example, the automobile manufacturing QS9000)

IEC 61315 / FOTP231 Calibration of Fiber Optic Power Meters

Kingfisher conforms to this standard for the calibration of Optical Power Meters.

Since 1993, our laboratory has used similar concepts to those embodied in this document. 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).

This specialised document describes in great detail how establish the calibration uncertainty of fiber optic power meters.
