IEC 60335-2-12:2024 deals with the safety of electric warming plates, warming trays and similar appliances intended to keep food or vessels warm, for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances.
Appliances intended for normal household and similar use and that can also be used by laypersons in shops, in light industry and on farms are within the scope of this standard. However, if the appliance is intended to be used professionally to keep vessels warm or to process food for commercial consumption, the appliance is not considered to be for household and similar use only.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or in aircraft, additional requirements can be necessary;
– in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
– appliances made of flexible material, such as textile material;
– appliances intended exclusively to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– appliances intended exclusively for commercial catering (IEC 60335 2 49, IEC 60335 2 50);
– appliances intended exclusively industrial purposes;
– warming cabinets.
This sixth edition cancels and replaces the fifth edition published in 2002, Amendment 1:2008 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, 5.2, 7.12, 15.2, 15.101, 24.1.5);
c) application of test probe 19 (8.1.1, 20.2, B.22.3, B.22.4);
d) clarification of applicability of requirements for remote operation (22.40, 22.49, 22.51).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
