IEC 61340-2-3

IEC 61340-2-3:2016 describes test methods for the determination of the electrical resistance and resistivity of solid materials used to avoid electrostatic charge accumulation, in which the measured resistance is in the range 10K Ohm to 1T Ohm. It takes account of existing IEC/ISO standards and other published information, and gives recommendations and guidelines on the appropriate method. This edition includes the following significant technical changes with respect to the previous edition:
a) a distinction has been introduced between instrumentation used for laboratory evaluations, instrumentation used for acceptance testing and instrumentation used for compliance verification (periodic testing);
b) an alternative electrode assembly is described, which can be used on non-planar products or when the dimensions of the product under test are too small to allow the larger electrode assembly to be used;
c) the formulae for calculating surface and volume resistivity have been modified to correspond with common industry practice in the main areas of application for the IEC 61340 series.
