Calibration Service for Testing Machines

MARUI's calibration division was registered as Accredited Calibration Laboratories of "Force" and "Unconfined"

Classification of Measurement Force
Classification of Force Force Gauge Unconfined
Items of Calibration [Annular spring type force gauge]
[Load Cell]

[Unconfined compression apparatus]
Range of Capacity 500N - 100 kN 100 N - 3000 kN

MARUI's calibration division had been assessed and certified in the quality and technique requirements for related regulations based on the Measurement Law and ISO/IEC 17025 by International Accreditation Japan (IAJapan). Now the registration has been transferred based on Japan Calibration Service System and also accredited as a laboratory that meets the requirements for Mutual Recognition Arrangements (MRA), and is allowed to issue calibration certificates with certified symbol mark since February 13, 2006.

The International Accreditation Japan (IAJapan) that registers, assesses, and manages calibration laboratories is in mutual agreement with International Laboratory Accreditation Cooperation (ILAC) and Asia Pacific Laboratory Accreditation Cooperation (APLAC).

MARUI's calibration division signed for the certified international standard service and is issued the Certificate of Accreditation for the calibration laboratory that meets the requirements for international MRA.
