16.6 Measurement Uncertainty 

 

The measurement uncertainty describes the overall uncertainty of the given measured 
value during the operation of the EUT. 
Measurement uncertainty of ESD test is: 

± 7 % 

The measurement uncertainty is given with a confidence of 95%, k=2. 
The measurement uncertainty is traceable to internal procedure TI-036.

Note: As an alternative method, a non-homogeneous field strength ≥3 V/m of similar 

characteristics as the test specification (e.g. generated by a dummy GSM portable 
telephone) may be applied in a shielded room. 
The dummy shall be placed on a non-metallic stand with a height of 80 cm, at a 
distance of 1 m to the EUT (see Figure 11). The front side of the EUT shall be 
placed in parallel to the antenna line of sight. The position shall be described in the 
measurement report. 
In case of dispute, measurements shall be carried out in accordance with IEC 
61000-4-3, with measurement conditions given in 5.8.4 and Table 23, and filter B.2 
replaced by B.4.
