IEC 60335-2-120:2024(Main)
Household and similar electrical appliances - Safety - Part 2-120: Particular requirements for the safety of appliances for the generation of directly inhalable aerosols

IEC 603352-120:2024 deals with the safety of appliances for generation of directly inhalable aerosols, their rated voltage being not more than 250 V for single-phase appliances, and other appliances including direct current (DC) supplied appliances and battery-operated appliances.
Examples of the appliances that are within the scope of this standard are:
- vapour and aerosol appliances;
- personal vaping appliances with or without nicotine;
- electronic cigarettes;
- electronic nicotine delivery systems (ENDS);
- electronic non-nicotine delivery systems (ENNDS);
- electronic tobacco heating appliances for heated tobacco products.
This standard does not apply to:
- medical ventilators,
- humidifiers (IEC 60335-2-98).
These requirements do not cover the consumables, such as e-liquids and other inhaled aerosol substances, wicks, and other particulate matter inhaled during use, nor do they cover substances in the emissions from the operation of the appliances. For example, heavy metal emissions in the aerosol and environmental exposure are not covered by this standard. These requirements do not consider the physiological effects of any consumable used with the appliances. This International Standard does not cover requirements or prohibitions of the labelling, packaging and contents of nicotine-containing or nicotine-consuming products that are strictly regulated by law of the relevant jurisdiction.

IEC 60335-2-41:2024(Main)
Household and similar electrical appliances - Safety - Part 2-41: Particular requirements for pumps

IEC 60335-2-41:2024 deals with the safety of electric pumps for liquids having a temperature not exceeding 90 °C, intended for household and similar purposes, 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 and battery-operated appliances. Examples of appliances within the scope of this standard are
- aquarium pumps;
- garden pond pumps;
- shower-boost pumps;
- sludge pumps;
- submersible pumps;
- table fountain pumps;
- vertical wet pit pumps.
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 ap-pliances that are encountered by all persons in and around the home. However, in gen-eral, 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 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 authori-ties, the national authorities responsible for the protection of labour and similar au-thorities.
This standard does not apply to
- stationary circulation pumps for heating and service water installations (IEC 60335-2-51);
- pumps for flammable liquids;
- pumps intended exclusively for industrial purposes;
- pumps intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- pumps incorporating chlorinators of the electrolytic type.
Pumps incorporated in appliances are not covered by this standard unless a specific ref-erence is made.
This fifth edition cancels and replaces the fourth edition published in 2012. 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) modification or conversion of some notes to normative text (Clause 1, 7.12.1, 25.7);
c) introduction of IEC 60417 symbol for maximum operating depth and indoor use only (7.1, 7.6, 7.12.1);
d) clarification of requirements for aquarium pumps and garden pond pumps;
e) addition of legibility requirements for markings exposed to solar radiation (7.14);
f) clarification of pumps subjected to test probe 18 (8.1.1, 20.2);
g) introduction of accessible surface temperature limits (Clause 11);
h) addition of requirements for IEC 61984 connectors for pumps intended for permanent connection to fixed wiring (22.107, 24.1.5, 24.1.101, 25.3).
i) clarifications on remote operation for pumps in scope of this standard (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.
