Hioki, the JCSS, ISO/IEC 17025, and MRAs

Hioki (Head Office) is a JCSS calibration provider. JCSS calibration certificates issued by Hioki include language certifying compliance with ISO/IEC 17025 and MRAs and bear certification symbol marks (“ilac-MRA,” “JCSS,” and “IAJapan”).
Certification certificates bearing certification symbols serve as evidence of the following
- Traceability to Japanese national measurement standards
- The technological capabilities of the calibration provider
- Acceptance in international MRA member countries (APAC and ILAC)
Examples of certification systems other than JCSS that satisfy ISO/IEC 17025
NVLAP, A2LA (U.S.A.), UKAS (UK), DKD (Germany), NATA (Australia), CNAS (China), KOLAS (South Korea), JAB (Japan)
*Related terminology
- ISO/IEC 17025 (JIS Q 17025)
