ISO/IEC 17025? Why is it important?

What is ISO/IEC 17025? ISO/IEC 17025 was first issued in 1999 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It is the single most important standard for calibration and testing laboratories around the world. Laboratories that are accredited to this international standard have demonstrated that they are technically competent and able to produce precise and accurate test and/or calibration data.


ISO/IEC 17025 defines the key elements of an acceptable calibration document. In fact, this is a global standard for quality systems of testing and cakibration laboratories.


What is Accreditation? Accreditation is a voluntary, third party-reviewed process. As part of accreditation, a laboratory's quality management system is thoroughly evaluated on a regular basis to ensure continued technical competence and compliance with ISO/IEC 17025. Laboratory accreditation can only be granted by an accreditation body, or AB. Although there are a number of accreditation bodies in the US, customers should choose calibration and testing laboratories accredited by ABs having an MRA with ILAC.
