This International Standard specifies requirements for cord sets and interconnection cord sets for household and similar general purpose equipment. It does not apply to cord sets for industrial purposes (with plugs and connectors according to IEC 60309) nor to cord extension sets. NOTE Although electrical supply flexes provided with rewirable plugs and connectors are not cord sets in the sense of this standard, but considered as being similar to cord sets and serving the same purpose, it is recommended to apply the requirements as specified in this standard to such assemblies as well as far as is reasonable.
