Guide to ISO/IEC 17025:2017 Accreditation For Calibration Laboratories

For calibration laboratories, ISO/IEC 17025 accreditation is a demonstration of their technical competence and capability to produce valid calibration results.

What is ISO/IEC 17025:2017 Standard?

The ISO/IEC 17025 standard lists the requirements for calibration laboratories to prove their competence and ability to produce valid results. Introduced for the first time in 1999, the 17025 standard has evolved to incorporate modern industry and laboratory practices. The latest revision of the standard was introduced in 2017.

What is Accreditation?

Accreditation against ISO/IEC 17025 is the official recognition that a laboratory has the competence, management systems, and resources to deliver valid and reliable calibration results on a consistent basis. To accomplish this accreditation, an external body, such as UKAS, PJLA, or EIAC, conducts a detailed assessment of the laboratory’s procedures, staff competence, equipment, and laboratory environment. This independent confirmation gives assurance to customers that laboratory operations are aligned with internationally accepted standards and practices.

Why ISO/IEC 17025 is Important for Calibration Laboratories?

ISO/IEC 17025 accreditation means that the calibration results produced by the laboratory are accepted worldwide without the requirement of repeated testing across borders. It assures customers and regulatory bodies that the laboratory meets globally accepted standards and is periodically assessed by an independent body. Accreditation provides a calibration laboratory with a clear advantage over its competitors. For example, a calibration lab providing services to an aerospace company fails to secure its contract because its non-accredited calibrations were not accepted by the company’s clients in Europe.

If an organization has an internal calibration laboratory catering to its calibration requirements, ISO 17025 accreditation of it is equally important for lifting customer confidence in its products.
