Temperature Humidity Atmospheric pressure

15 °C – 35 °C 30 % - 60 % 800 hPa – 1060 hPa

If explicitly required in the basic standard or applied product standard the climatic values are recorded and documented separately in this test report.

Measurement uncertainties ...... : For all measurements where guidance for the calculation of the instrumentation uncertainty of a measurement is specified in EN 55016-4-2, EN 61000-4 series or a product standard, the measurement instrumentation uncertainty has been calculated and applied in accordance with these standards. In all cases if the test laboratory uncertainty is larger than the value for UCISPR given in EN 55016-4-2 the uncertainty is included in the test report annex. In case the standards in the EN 61000-4 series or the product standard requires the indication of the uncertainty in the report these uncertainty values are included in the annex.

7 IMMUNITY

7.1 General information

Performance criteria as defined by the standard

Criterion Description from standard

A

The EUT shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the EUT is used as intended. If the performance level is not specified by the manufacturer, this may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.

B

The EUT shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the EUT is used as intended. The performance level may be replaced by a permissible loss of performance. However, during the test degradation of performance is allowed but no change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.

C Temporary loss of function is allowed during the test, provided the function is self-recoverable or can be restored by the operation of the controls.
