Repair and Calibration - Hioki
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)
