All ISOLAB and associate labs have earned the widest scope of ISO/IEC 17025 accreditation in the industries we serve. But ISOLAB’s own internal quality requirements go well beyond this international standard.

Scope of Accreditation


Traceability is a core element of our registration and accreditation processes. Our standards are traceable to NIST, equivalent national or international sources, or physical constants, as appropriate. We have a true reverse traceability system and provide appropriate notifications when required. You can have confidence in your measurement results, because they are related to a national/international standard with known uncertainties.
