Calibration Certificates, Traceability System Diagram, and Certificates of Non-Conformity

An MRA (Mutual Recognition Arrangement) is an agreement under which multiple countries recognize each other’s conformity assessments.

Under an international mutual recognition agreement, accreditation organizations participating in the agreement perform mutual assessments. Management and operation of accreditation organizations are based on ISO/IEC 17011 international standards. Assessments determine whether ISO/IEC 17025 accreditation standards are being followed.

Tohnichi Manufacturing’s Torque Standards Calibration Laboratory is an accredited entity under an international MRA and is qualified to issue torque wrench tester calibration certificates with the ILAC-, MRA- and JCSS-registered accreditation symbols.
