IEC 60189-1:2018 specifies mechanical, electrical and climatic test methods for low-frequency cables and wires designed for use in telecommunication inside plants and equipment and in electronic devices employing similar techniques. This fourth edition cancels and replaces the third edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Test methods for dielectric strength and insulation resistance that were referenced in the previous edition have been withdrawn. They have been replaced with references to similar test methods described in current standards.
b) References to the IEC 60811 series have been updated as the numbering of this series has completely been changed.
