The object of this document is to investigate the effect of high humidity at constant temperature without condensation on a specimen over a specified period. It is applicable to small equipment or components as well as large equipment and can be applied to both heat-dissipating and non-heat-dissipating specimens. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) revision of the requirements for the test chamber;b) revision of the severities and including the dew point temperatures;c) change of the temperature tolerances of the test to limits;d) inclusion of a specified preconditioning procedure;e) inclusion of a new figure for clarification purposes;f) revision of standardized requirements for the test report.
