Overview
IEC 60335-2-6:2014/AMD1:2018 is an important amendment issued by the International Electrotechnical Commission (IEC) under Technical Committee 61, focusing on the safety requirements for household and similar electrical appliances, specifically addressing stationary cooking ranges, hobs, ovens, and similar appliances. This amendment updates and refines the safety provisions of the base standard IEC 60335-2-6:2014 to ensure enhanced user protection and improved appliance reliability under practical operating conditions.
The amendment emphasizes safety aspects related to heating units, moisture resistance, mechanical strength, and electronic control systems. It is essential for manufacturers, testing bodies, and regulatory authorities responsible for stationary cooking appliances to refer to this amendment to comply with the latest safety standards.
Key Topics
-
Heating Unit Operation
The amendment outlines conditions for operating multiple heating units per phase using a diversity factor for calculating rated currents. It also introduces provisions for flexible induction cooking zones, specifying how induction elements are tested using multiple vessels to reflect real-life use and ensure safety.
-
Marking and Controls
Requirements for clear marking of flexible induction cooking zones and controls are specified. This includes assigning controls, touch panels, and displays to specific cooking vessels to avoid user confusion and potential hazards during operation.
-
Moisture and Spillage Resistance Testing
Detailed procedures for spillage testing are included, ensuring cooking ranges, hobs, and ovens can withstand water and food spillages without compromising safety. Testing involves the use of standardized spillage solutions poured on heating zones, controls, ventilating openings, drip trays, hob lids, and work surfaces to mimic realistic scenarios.
-
Mechanical Strength
Mechanical strength tests are enhanced by clarifying test methods and conditions, such as performing strength tests without removing heating element guards. Vessel dimensions used in tests are updated to reflect typical usage.
-
Construction and Electronic Controls
Restrictions on delayed start timers controlling grill elements and enhanced requirements for programmable electronic circuits are introduced. Appliances with electronic controls must prevent unsafe simultaneous activation of heating elements and motors, verified through software evaluation and fault condition testing outlined in Annex R.
Applications
IEC 60335-2-6:2014/AMD1:2018 is primarily applicable to:
- Manufacturers designing and producing stationary cooking appliances such as electric cooking ranges, induction hobs, built-in ovens, and grills.
- Testing laboratories evaluating electrical safety, mechanical durability, moisture resistance, and control system reliability of cooking appliances.
- Regulatory bodies adopting safety standards for certification and market compliance.
- Product developers implementing flexible cooking zones and programmable electronic controls to meet user safety requirements.
- Quality assurance teams ensuring appliances comply with safety standards during production.
This amendment aids in improving consumer confidence by ensuring cooking appliances withstand typical household usage conditions, preventing electrical hazards, overheating, and control malfunctions.
