IEC 61969-3:2011 specifies a set of basic environmental requirements and tests, as well as safety aspects for outdoor enclosures under conditions of non-weatherprotected locations above ground. The purpose of this standard is to define a minimum level of environmental performance in order to meet requirements of storage, transport and final installation. It is the intention to establish basic environmental performance criteria for outdoor enclosure compliance. This second edition cancels and replaces the first edition issued in 2001. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows. Table 1 and Table 6 have been extended with requirements and tests, relevant for outdoor conditions.
