ISO/IEC 17025
What ISO/IEC 17025 is, and who needs it
ISO/IEC 17025 sets the requirements for the competence of testing and calibration laboratories. An important distinction: laboratories are accredited, not certified - in India that accreditation is granted by NABL. What accreditation demonstrates is technical competence to produce valid results, which is a higher bar than having a documented system.
The essentials
What the standard asks of you
Competence, not just a system
The assessment examines whether your laboratory can technically produce valid results - methods, equipment, staff and environment, not only documentation.
Method validation
Demonstrating that the methods you use are fit for purpose and that results can be relied on.
Measurement uncertainty
Estimating and reporting uncertainty, so results carry a meaningful confidence rather than a bare number.
Metrological traceability
Calibration traceable to recognised references, which underpins the validity of everything you report.
Impartiality and confidentiality
Structural requirements to ensure results are not influenced by commercial or other pressure.
Recognition of your results
Accredited results carry weight with regulators, customers and across borders - frequently the commercial reason laboratories pursue it.
