Specifies the procedures and criteria for the in-service safety inspection and testing of electrical equipment which is designed for connection by flexible cord. It also applies to cord extension sets, portable outlet devices, portable residual current devices and portable isolation transformers. Appendices include detailed test methods. It does not cover type approval tests for the design and construction of the equipment, nor does it include any procedural rules for the safe use of equipment.

This Standard specifies procedures for the in-service safety inspection and testing of single and polyphase electrical equipment, other than fixed equipment, 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, cord-connected portable residual current devices and portable isolation transformers.The Standard applies both to equipment purchased and to equipment manufactured or modified by users.Equipment connected by fixed wiring and large, stationary equipment connected by a flexible cord which is not flexed during normal use or exposed to abuse or damage in a hostile environment, e.g. window-mounted air conditioners, is not normally considered to represent a hazard sufficient to warrant routine in-service electrical safety testing. Accordingly, the testing of such equipment is not required by this Standard, although other standards or statutory requirements may specify such testing.Specialized electronic equipment, e.g. portable computers, may sustain damage if not tested in accordance with manufacturers' instructions. Accordingly, advice should be sought from the equipment manufacturer or agent before proceeding with in-service tests.
