This clause of Part 1 is replaced as follows:

1.1 This Part of International Standard IEC 60730 applies to electrically operated door locks intended to prevent the opening of doors in equipment for household and similar use.Throughout this Part 2 the word “door” means a door, cover or lid. The words “door lock” mean electrically operated door lock.This Part 2 is also applicable to door locks for appliances within the scope of IEC 60335.This Part 2 applies to door locks with electrical circuits and control circuits which are, for example, operated by bimetals, magnet coils, memory metals, pressure elements, temperature-sensitive expansion elements or electronic elements.

1.1.1 This Part 2 applies to the inherent safety, to the operating values, operating sequences where such are associated with equipment protection, and to the testing of door locks used in, on or in association with, household or similar equipment.Door locks for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this Part 2.Throughout this Part 2, the word “equipment” means “appliance” and “equipment.”This Part 2 does not apply to door locks designed exclusively for industrial applications.This Part 2 is also applicable to individual door locks utilized as part of a control system or door locks which are mechanically integral with multi-functional controls having non-electrical outputs.

1.2 This Part 2 applies to door locks with a nominal voltage not exceeding 660 V and a nominal current not exceeding 63 A.

1.3 This Part 2 does not take into account the response value of an automatic action of a door lock, if such a response value is dependent upon the method of mounting the door lock in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply.
