|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 and testing laboratories.
In addition to establishing a quality system, documentation, and personnel requirements, it directs calibration labs to:
ISO17025 is the single most important metrology standard for test and 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 manufacturers' QS9000).*
