    Abstract - (Show below) - (Hide below)

    IEC 60255-27:2013 describes the product safety requirements for measuring relays and protection equipment having a rated a.c. voltage up to 1 000 V with a rated frequency up to 65 Hz, or a rated d.c. 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 details essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user. This new edition includes the following significant technical changes with respect to the previous edition:
    - the removal of tables and diagrams which are from other standards and referring instead directly to the source standard;
    - all aspects of IEC 60255-5 have been covered and this standard will be withdrawn.
