This part of the IEC 60255 series describes the product safety requirements for measuring relays and protection equipment having a rated AC voltage up to 1 000 V, or a rated DC voltage up to 1 500 V. Above these limits, IEC 60664-1 is applicable for the determination of clearance, creepage distance and withstand test voltage. This standard specifies essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user, this standard is intended to describe only product safety requirements, functional performance of the equipment is not covered.
