Overview
IEC 60335-2-12:2002/AMD2:2017 is an important international amendment issued by the International Electrotechnical Commission (IEC) focusing on the safety of household and similar electrical appliances, specifically warming plates and related appliances. As part of the IEC 60335 standard series, this amendment outlines particular safety requirements to ensure safe operation and use of warming plates by defining temperature limits, marking protocols, testing methods, and construction criteria. The amendment was developed by IEC Technical Committee 61, which specializes in the safety of household electrical appliances.
This amendment supports manufacturers, testing organizations, and regulatory bodies in implementing uniform safety standards worldwide to reduce hazards linked to hot surfaces and electrical heating appliances. It enhances user protection by specifying maximum temperature rises for external surfaces while mandating clear safety markings.
Key Topics
Hot Functional Surfaces
Defines “hot functional surface” as any surface intentionally heated by an internal heat source to perform the appliance's intended function, highlighting the critical areas requiring special safety attention.Marking and Instructions
Requires appliances to be marked with a clear "CAUTION: Hot surface" label or the IEC symbol IEC 60417-5041 to warn users of potential burn hazards. The height of the warning triangle symbol must be at least 10 mm and must be clearly visible during normal use, excluding being placed directly on hot functional surfaces.Temperature Limits for External Surfaces
Establishes maximum permissible temperature rises on external accessible surfaces to reduce the risk of burns:- Bare metal surfaces: max 38-42 K rise depending on installation height
- Coated metals and plastics: defined temperature rises based on coating thickness and material type
- Glass and ceramic surfaces: higher allowed temperature rises due to material properties
Measurement and Testing Methods
Defines a standardized test probe (force applied of 4 N ± 1 N) for measuring the temperature rise on flat, accessible external surfaces after a 30-second contact period to ensure compliance with temperature limits during normal operation.Exemptions from Temperature Limits
Includes practical exceptions such as handles, knobs, lids, and areas near hot functional surfaces, recognizing their operational necessity and designed safe heat exposure.
Applications
The IEC 60335-2-12:2002/AMD2:2017 amendment applies to:
Manufacturers of warming plates and similar household appliances
Helps ensure products meet international safety requirements before market release.Testing laboratories and certification bodies
Provides precise methodologies and criteria for safety assessment to certify appliances comply with temperature and marking standards.Regulatory agencies and standardization groups
Facilitates consistent enforcement of safety standards, improving consumer protection against burns and fire risks associated with warming plates.Product designers and engineers
Offers guidance on thermal safety, materials selection, and product labeling to minimize user hazards and improve appliance safety profiles.

7.15 Addition:
The marking specified for hot surfaces shall be clearly visible when the appliance is operated
as in normal use, including when actuating any switch, adjusting any control or opening a lid
or door. It shall not be placed on a hot functional surface or on surfaces that are exempted
from the limits of Table 101.
11 Heating
Add the following new subclause:
11.3 Addition:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 101 is used to measure the temperature rises of external accessible
surfaces specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface
