IEC 60721-2-1:2013 presents classifications of open-air climates in terms of temperature and humidity. It is intended to be used as part of the background material when selecting appropriate temperature and humidity severities for product testing and application. This second edition cancels and replaces the first edition, published in 1982, and constitutes a technical revision. The main changes with respect to the previous edition are in the definitions of climate types.
