IEC 60068-2-53:2010 provides a description of test methods and guidance for testing equipment or components under combined climatic and dynamic conditions. The purpose of combined testing is to investigate to what extent the equipment or components are affected by combined climatic and dynamic tests. This second edition cancels and replaces the first edition of IEC 60068-2-50, published in 1983,the first edition of IEC 60068-2-51, published in 1983 and the first edition of 60068-2-53, published in 1984 and constitutes a technical revision. The main changes with respect to the previous editions of all three standards cited above is to update and group tests. In this way it allows for the possibility to use different kinds of vibration excitation:
- sine, random or mixed mode;
- or shocks, with different tests for climatic conditions;
- cold, dry heat, change of temperature or constant and cyclic damp heat.
