3.3 Performance level
The test results shall be classified in terms of the loss of function or degradation of performance of the equipmentunder test, relative to a performance level defined by its manufacturer or the requestor of the test, or agreedbetween the manufacturer and the purchaser of the product.
Definition related to the performance level:
based on the used product standard (table 2 of EN 61326-1 for continuous monitored operationequipment)
based on the declaration of the manufacturer, requestor or purchaser
During the test a value of current was monitored, maximum variation allowed 5% (declared by manufacturer).
Criterion A:
Definition: normal performance within limits specified by the manufacturer, requestor or purchaser:
Criterion B:
Definition: temporary loss of function or degradation of performance which ceases after the disturbance ceases, andfrom which the equipment under test recovers its normal performance, without operator intervention:
Criterion C:
Definition: temporary loss of function or degradation of performance, the correction of which requires operatorintervention:

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 beerrors within the calibration limits of the equipment and facilities. The measurement uncertainty was calculated forall measurements listed in this test report according to CISPR 16 - 4 „Specification for radio disturbance andimmunity measuring apparatus and methods – Part 4: Uncertainty in EMC Measurements“ and is documented inthe Nemko Spa Technical Procedure PT 179. Furthermore, component and process variability of devices similar tothat tested may result in additional deviation. The manufacturer has the sole responsibility of continued complianceof the device.Hereafter the best measurement capability for Nemko Spa laboratory is reported:
