(Additional requirements for markings. See 1.7 NOTE) Calibration Measurement uncertainty Evaluation of results All instruments used in the tests given in this test report are calibrated and traceable to national or international standards. Further information about traceability will be given on request. Measurement uncertainties are calculated for all instruments and instrument set-ups given in this report. Calculations are based on the principles given in the standard EA-4/02 (Dec. 1999), IEC Guide 115:2007. Further information about measurement uncertainties will be given on request. If not explicitly stated otherwise in the standard, the test is passed if the measured value is equal to or below (above) the limit line, regardless of the measurement uncertainty. If the measured value is above (below) the limit line, the test is not passed - ref IEC Guide 115:2007. The instrumentation accuracy is within limits agreed by IECEE-CTL. TRF No. IEC60950_1F
