Certification of one liner as Type L2 according
IEC 61340-4-4: Edition 3.0: 2018
Date: September 2, 2019

Summary

Our reference: KU

The liner (marked STAT-FCB) meets the requirements for a liner Type L2 configuration1 according IEC 61340-4-4: Edition 3.0: 2018.
The surface resistivity of both sides of the liner are between 1,0 × 109 Ω and1,0 × 1012 Ω.
The determination of the breakdown voltage is not necessary.

Applied Testing Procedure
SOP-No: 201 (Measuring of the surface resistance)

Test set-up
The tests were carried out in the electrostatic lab of the TÜV SÜD Process Safety in Basel.
For the surface resistance the Megohmmeter was used with the circle electrode according IEC 61340-23. For the conversion to resistivity values the following equation are used:s = Rx(d1 + g) · /gwheres is the surface resistivity (W);Rx is the measured surface resistance (W);d1 is the diameter of the inner contact electrode (m);g is the distance (gap) between the contact electrodes (m).

For the used electrode, the factor (d1 + g) · /g= 10.455
The surface resistivity test was done inside a climatic chamber with a temperature of 23°C and 20% relative humidity. The measuring voltage was 100V.
End of experimental part: August 30, 2019.
