This standard is also applicable to individual TIMERS utilized as part of a control system or TIMERS which are mechanically integral with multifunctional controls having non-electrical outputs. This standard does not apply to time-delay switches (T.D.S.) within the scope of IEC 60669-2-31).
Throughout this standard the word "TIMERS" means TIMERS and TIME SWITCHES, unless the type is specifically mentioned.
