Section numbers of test and performance requirements refer to EN 140 000. 
Test methods refer to IEC 68-2. See also CECC 40 401-803. 
The statements regarding the requirements are based on the stability class 0,5. 
Reference measurements are to be performed at 20°C (see EN 140 000). At low ohmic values the distance of the measuring clip has to be considered (24±2mm). Less than 1k-Ohm should always be measured with the 4-wires-method.
