What is ISO/IEC 17025 accreditation?

ISO 17025 is an international standard containing general requirements for the competence of testing and calibration laboratories. It is fundamentally a system designed to ensure repeatability and quality of services provided by laboratories. We were awarded our ISO/IEC 17025:2005 accreditation in 2016 by the certified accreditation body (CAB) Perry Johnson Laboratory Accreditation, Inc. (PJLA Acreditation # 87144).


CAIS is the oldest and largest geochemistry/radiocarbon AMS dating lab to receive this accreditation. We are currently accredited for Radiocarbon and Stable Isotope Ratio Mass Spectrometry of Biological and Chemical Materials, specifically: radiocarbon (14C) content in carbon-containing samples by accelerator mass spectrometry (AMS) and liquid scintillation counting (LSC), stable isotope ratios of carbon, nitrogen, oxygen and hydrogen by isotope ratio mass spectrometry (IRMS), and biobased carbon content of solid and liquid materials using the standard method ASTM D6866.
