This document applies to accessories for use when the ambient temperature is normally within the range of -25 °C to +40 °C.
These accessories are intended to be connected to cables of copper or copper alloy only. Interchangeability requirements are defined for IP20 accessories.
NOTE The conditions of use indoors are based on the limitations given by IEC 60364-5-51:2005, Table 51A, AD1.
Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this document.
