UL Standard for Safety Automatic Electrical Controls – Part 2-12: Particular Requirements for Electrically Operated Door Locks
|Publication Date:||11 May 2017|
This part of IEC 60730 applies to ELECTRICALLY OPERATED DOOR LOCKS for use in, on or in association with equipment, including equipment for heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.
NOTE 1 Throughout this standard, the word ″equipment″ includes ″appliance″ and ″control system″.
This standard also applies to ELECTRICALLY OPERATED DOOR LOCKS for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications.
This standard does not apply to ELECTRICALLY OPERATED DOOR LOCKS intended exclusively for industrial process applications unless explicitly mentioned in the equipment standard.
This standard does not apply to ELECTRICALLY OPERATED DOOR LOCKS intended for security access applications.
NOTE 2 Standards that cover these applications are under IEC Technical Committee 79.
This standard 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, or in association with equipment.
This standard is also applicable to door locks for appliances within the scope of IEC 60335-1.
NOTE Throughout this standard, the word "door" means "door, cover or lid". The words "door lock" mean "electrically operated door lock".
This standard 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 or employing motors.
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 standard.
This standard is also applicable to the FUNCTIONAL SAFETY of LOW COMPLEXITY SAFETY RELATED SYSTEMS and CONTROLS employing door locks as the actuating element.
This standard applies to door locks with electrical circuits and CONTROL circuits which are, for example, operated by bimetals, magnet coils, memory metals, pressure elements, temperature-sensitiv
This standard applies to MANUAL CONTROLS when such are electrically and/or mechanically integral with door locks.
NOTE Requirements for manual switches not forming part of a door lock are contained in IEC 61058-1.
This standard applies to a.c. or d.c. powered door locks with a rated voltage not exceeding 690 V a.c. or 600 V d.c.
This standard 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 CONTROL 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 equipment standard or as determined by the manufacturer shall apply.
This standard applies also to door locks incorporating ELECTRONIC DEVICES, requirements for which are contained in Annex H and door locks using THERMISTORS, requirements for which are contained in Annex J.
