IEC 60749-5:2023 is available as IEC 60749-5:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60749-5:2023 provides a steady-state temperature and humidity bias life test to evaluate the reliability of non-hermetic packaged semiconductor devices in humid environments. This test method is considered destructive. This edition includes the following significant technical changes with respect to the previous edition:
a) The specification of the test equipment is changed to require the need to minimize relative humidity gradients and maximize air flow between semiconductor devices under test;
b) The specification of the test equipment fixtures is changed to require the avoidance of condensation on devices under test and on electrical fixtures connecting the devices to the test equipment;
c) replacement of references to .virtual junction. with .die..
