DIN EN 60721-2-1:2015-10

Part 2-1 of the IEC 60721 series provides a selection of open-air climate classifications, in terms of temperature and humidity, which represent the conditions most frequently met by products while being transported, stored, installed and used. It is intended to be used as part of the background material when selecting appropriate temperature and humidity severities for product testing and application. The climates cover all areas of the world, excluding the central Antarctic and high altitudes above 5 000 m. The main changes compared to HD 478.2.1 S1:1989 include in the definition of climate types. The responsible committee is DKE/K 131 "Umgebungsbedingungen, Klassifizierung und Prüfungen" ("Environmental conditions, classification and methods of test") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
