This Standard specifies procedures for the safety inspection and testing of single and polyphase electrical equipment, which is in-service, or available for hire or resale, and which is designed for connection by a flexible power supply cord and plug to a low voltage supply. It applies also to cord extension sets, electrical portable outlet devices, portable residual current devices and portable isolation transformers. Fixed equipment is not normally considered to represent a hazard unless the flexible cord is subject to flexing in normal use, or the equipment is in a hostile environment, in either case, this Standard will apply.
