LABORATORY LOCATION: (PERMANENT LABORATORY)

METCAL TECHNOLOGIES (M) SDN. BHD. NO. 36, CANGKAT BUKIT BELAH 11920 BAYAN LEPAS PULAU PINANG MALAYSIA

FIELDS OF CALIBRATION: DIMENSIONAL, MASS, FORCE, TORQUE, TEMPERATURE, PRESSURE, VOLUME, ELECRTRICAL, TIME AND FREQUENCY

This laboratory has demonstrated its technical competence to operate in accordance with MS ISO/IEC 17025:2005 (ISO/IEC 17025:2005). This laboratory’s fulfillment of the requirements of ISO/IEC 17025 means the laboratory meets both the technical competence requirements and management system requirements that are necessary for it to consistently deliver technically valid test results and calibrations. The management system requirements in ISO/IEC 17025 are written in language relevant to laboratory operations and operate generally in accordance with the principles of ISO 9001 (see Joint ISO-ILAC-IAF Communiqué dated April 2017). * The expanded uncertainties are based on an estimated confidence probability of approximately 95% and have a coverage factor of k=2 unless stated otherwise.
