Section numbers of test and performance requirements refer to IEC 115-1.
Test methods refer to IEC 60068-2. See also DIN EN 140401-803.
The statements regarding the requirements are based on the stability class 0.5.
Reference measurements are to be performed at 20° (see EN 140 000).At low ohmic values the distance of the
C
measuring clip has to be considered (24±2mm). Less then 1k-Ohm should always be measurd with the 4-wires-
method.
