Quality methodology
ISO/IEC 17025:2017 — Competence of testing and calibration laboratories
The international standard against which testing laboratories are accredited.
Accreditation to ISO/IEC 17025 is granted by an accreditation body for a defined scope of tests. A laboratory's accreditation certificate and scope, not a logo, are what establish that a particular test was performed under it. Lot records on this site name the testing laboratory and record its accreditation only as documented.
