of 30 4.4 Statement of the measurement uncertainty The data and results referenced in this document are true and accurate. The reader is cautioned that there may be errors within the calibration limits of the equipment and facilities. The measurement uncertainty was calculated for all measurements listed in this test report according to CISPR 16-4 Specification for radio disturbance and immunity measuring apparatus and methods Part 4: Uncertainty in EMC Measurements and is documented in the Nemko Spa Technical Procedure PT 179. Furthermore, component and process variability of devices similar to that tested may result in additional deviation. The manufacturer has the sole responsibility of continued compliance of the device.
