IEC 60730-2-12:2015

Overview

IEC 60730-2-12:2015 - Automatic electrical controls, Part 2-12 - specifies particular requirements for electrically operated door locks used in or in association with equipment (e.g., heating, air‑conditioning and similar appliances). This third edition (2015) updates the previous edition and aligns the requirements with IEC 60730-1:2013 (Edition 5). It covers inherent safety, operating values, operating sequences and test methods for door locks up to rated voltages of 690 V a.c. or 600 V d.c., and is intended for equipment that may be used by the public (shops, offices, hospitals, farms, commercial/industrial settings). It does not apply to security access locks or door locks exclusively for industrial process applications unless the equipment standard explicitly includes them.

Key topics and technical requirements

• Scope and definitions: clear definitions for electrically operated door locks, locking, drop‑out value, locking/unlocking delays, locking force and locking security.
• Safety and functional requirements: requirements for inherent safety, operating values and safe operating sequences when door locks protect users or equipment.
• Testing and verification: endurance, mechanical strength, electrical strength and insulation resistance, moisture/dust resistance, heating, environmental stress and manufacturing deviation/drift tests.
• Electrical protection: protection against electric shock, provisions for protective earthing, terminals and terminations.
• EMC and immunity: emission and immunity requirements to ensure proper operation in the intended electromagnetic environment.
• Components and construction: constructional requirements, resistance to heat/fire/tracking, corrosion resistance, and requirements for threaded parts and connections.
• Electronic elements: special provisions for door locks incorporating electronics (Annex H) and thermistor‑based devices (Annex J).
• Classification and information: rating, classification, required documentation and marking for safe installation and maintenance.
• Modifications in Edition 3: alignment with IEC 60730‑1 Edition 5 and modified requirements for Class B and Class C control functions and fault behavior during safety shut‑down.

Applications

IEC 60730-2-12 is intended for electrically operated door locks that prevent access or control operation of equipment powered by electricity, gas, oil, solid fuel, solar thermal energy or combinations thereof. Typical use cases include door locks integrated into appliances and equipment where door control is safety‑relevant (e.g., equipment doors, covers or lids used by the public or lay operators).

Who should use this standard

• Appliance and equipment designers and manufacturers (heating, HVAC, domestic and commercial appliances)
• Product safety and compliance engineers ensuring conformity with automatic electrical control requirements
• Test laboratories and certification bodies performing type testing and conformity assessment
• Suppliers of door lock mechanisms and control systems integrating locking functions

Related standards

• IEC 60730-1:2013 (general requirements for automatic electrical controls) - to be read in conjunction with Part 2-12.
• Security‑access lock standards (IEC TC 79) - for locks intended for access control/security applications.
