1 Scope
This part of IEC 60721 presents fundamental properties, quantities for characterization, and a classification
of environmental conditions dependent on precipitation and wind relevant for electrotechnical
products.
It is intended to be used as background material when selecting appropriate severities
of parameters related to precipitation and wind for product applications.
When selecting severities of parameters related to precipitation and wind for product
application, the values given in IEC 60721‑1 should be applied.
