IEC 60335-2-31:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-31:2024 EXV includes the content of the references made to IEC 60335-1:2020.

IEC 60335-2-31:2024 deals with the safety of electric range hoods and other cooking fume extractors intended for installing above, beside, behind or under household cooking ranges, hobs and similar cooking appliances, their rated voltage being not more than 250 V including direct current (DC) supplied appliances. The cooking appliance can be supplied by electricity or other fuels, such as gas. Appliances not intended for normal household use but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen 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. However, in general, it does not take into account
- persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances incorporating electrostatic air filters, IEC 60335-2-65 also applies;
- for appliances 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, the national authorities responsible for buildings and similar authorities.
This standard does not apply to
- appliances intended for commercial purposes (IEC 60335-2-99);
- appliances 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 sixth edition cancels and replaces the fifth edition published in 2012, Amendment 1:2016 and Amendment 2:2018. 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, 22.8, 22.101, 22.102);
c) update of the installation requirements for the heating test to include down-draft systems (11.2);
d) addition of accessible surface temperature limits (11.3, 11.8);
e) introduction of IEC TR 62854 to determine compliance in case of doubt (22.14);
f) clarification of remote operation requirements for range hoods and other cooking fume extraction appliances (22.40, 22.49, 22.51);
g) clarification of 30.101 with respect to grease filters and odour extraction filters.
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.
