IEC 60335-2-61:2024 deals with the safety of electric thermal-storage room heaters for household and similar purposes that are intended to heat the room in which they are located, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances.
Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laypersons in shops, in light industry and on farms, are within the scope of this standard.
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
- this standard only applies to self-contained thermal-storage room heaters. However, it can be used as a guide, in so far as it reasonably applies, to determine the requirements and test specifications for other thermal-storage room heaters;
- for heaters incorporating direct-acting heating elements, IEC 60335-2-30 is also applicable;
- for heaters intended to be used in vehicles or on board ships or 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 intended exclusively for industrial purposes;
- heaters incorporated in the building structure;
- central heating systems;
- heaters for saunas (IEC 60335-2-53);
- flexible sheet heating elements for room heating (IEC 60335-2-96);
- heaters intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This third edition cancels and replaces the second edition published in 2002, Amendment 1:2005 and Amendment 2:2008. 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) deletion or conversion of some notes to normative text (Clause 1, 7.1, 10.1, 19.3.102, 24.101);
c) application of test probe 19 has been introduced (8.1.1, 20.2);
d) temperature limits have been updated and requirements for measurement were defined (Clause 11.3, 11.8, Table 101);
e) implementation of Figure 101 with the probe for measuring surface temperatures.
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.
