ISO/IEC 17025:2017 Accredited Calibration Laboratory
Right Weigh Scale, LLC is accredited by Perry Johnson Laboratory Accreditation, Inc. (PJLA) to ISO/IEC 17025:2017 — the international standard for the competence of testing and calibration laboratories.
Our accreditation covers Mass, Force, and Weighing Devices Calibration, performed both at our Hayward, California laboratory and on-site at your facility anywhere in the Bay Area and Northern California.
What ISO/IEC 17025 Accreditation Means for Your Business
Many calibration providers describe themselves as “ISO 17025 compliant.” Accreditation is different — and stronger.
Compliance is a self-declared claim that a company follows the standard. Accreditation means an independent, internationally recognized accreditation body (PJLA, a signatory to the ILAC Mutual Recognition Arrangement) has assessed our laboratory — our procedures, our reference standards, our measurement uncertainty calculations, and the technical competence of our technicians — and formally confirmed we meet ISO/IEC 17025:2017.
For you, that means:
- Audit-ready calibration certificates accepted by FDA, USP, GMP, ISO 9001, cannabis regulators (DCC), and other quality programs that require accredited calibration
- NIST-traceable measurements using ASTM Class 0 through Class 6 reference weights
- Defined measurement uncertainty on every accredited calibration, stated at a 95% confidence level
- Internationally recognized results through PJLA’s ILAC-MRA signatory status — certificates accepted across borders without re-calibration
