Hioki Becomes First Company in Japan to Earn JCSS Certification for DC Power Measurement

Hioki is pleased to announce that on January 29, 2021, it became the first company in Japan to register with, and earn certification under, the Japan Calibration Service System (JCSS) as a provider of calibration services for DC power measurement instruments. The JCSS registers calibration providers and certifies that they possess the technological capabilities necessary to offer calibration services that satisfy the requirements of the ISO/IEC 17025 international standard.

Demand for calibration services that have been certified under the ISO/IEC 17025 standard, which ensures reliable evidence of instrument calibration, has been growing recently in a range of industries including the automotive, nuclear power, aviation, medical, food, and military sectors.
In particular, IATF 16949, an international standard formulated by the International Automotive Task Force (IATF) defining quality management systems for the automotive industry, requires that measuring instruments being calibrated by an outside entity undergo ISO/IEC 17025 calibration. This requirement has led to an increase in the number of customers in the automotive industry requesting JCSS calibration.
As a result of its JCSS registration and certification as a provider of calibration services for DC power measurement instruments, Hioki expects to make even greater use of the JCSS in combined calibration of power meters and current sensors.
