    IEC 60050-445:2010 defines terms related to specified-time relays. This second edition cancels and replaces the first edition published in 2002 and constitutes a technical edition. This new edition has been revised in order to:
    - incorporate terms more commonly used by industry;
    - incorporate timing charts to help explain definitions involving a sequence of operations.
    It has the status of a horizontal standard in accordance with IEC Guide 108.
