Mechanical structures for electronic equipment - outdoor enclosures, environmental requirements, tests and safety aspects.
The standard specifies basic environmental requirements, tests and safety aspects for outdoor enclosures for electrical and electronic equipment installed above ground in locations without protection from weather.
It defines the minimum level of environmental resistance during storage, transport and final installation. Edition 3.0 (2020) aligned the climatic classes with ETSI EN 300 019 and the IEC 60721 series.
Compliance of a trackside cabinet with IEC 61969-3 confirms environmental testing (climate, precipitation, radiation, corrosion) of the outdoor enclosure according to defined classes - a reference point for uncovered trackside locations.
