IEC 60335-1:2020 deals with the safety of electrical appliances 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.
Appliances not intended for normal household use but which nevertheless may 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.
This standard deals with the reasonably foreseeable hazards presented by appliances that are encountered by all persons. 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.
Additional requirements may be necessary for appliances intended to be used in vehicles or on board ships or aircraft. In many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
This standard does not apply to:
– appliances intended exclusively for industrial purposes;
– 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);
– audio, video and similar electronic apparatus (IEC 60065);
– medical electrical equipment (IEC 60601 series);
– hand-held motor-operated electric tools (IEC 60745 series);
– information technology equipment (IEC 60950-1);
– transportable motor-operated electric tools (IEC 61029 series);
– audio/video, information and communication technology equipment (IEC 62368-1);
– electric motor-operated hand-held tools, transportable tools and lawn and garden machinery (IEC 62841 series).
This sixth edition cancels and replaces the fifth edition published in 2010, Amendment 1: 2013 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition (minor changes are not listed):

b) deleted some notes and converted many other notes, in whole or in part, to normative text;
c) changed some Annex designations from normative to informative;
d) introduced information on Guidance documents concerning the application of the safety requirements covered by IEC 60335 series and on how to retrieve them;
e) clarified requirements for PELV circuits;
f) clarification of requirements on measurement of power input and rated current when they vary throughout the operating cycle;
g) replaced normative Annex S with the informative Annex S "Guidance for the application of this standard on measurement of power input and current based on the requirements of 10.1 and 10.2 concerning the representative period";
h) introduced and clarified mechanical strength requirements for appliances with integral pins for insertion into socket-outlets;
i) revised requirements for battery-operated appliances;
j) introduced requirements for metal-ion batteries including a new Clause 12 Charging of metal-ion batteries;
k) introduced the application of test probe 18;
l) introduced requirements for appliances incorporating appliance outlets and socket-outlets accessible to the user;
m) revised and clarified requirements for appliances incorporating a functional earth;
n) introduced moisture resistance test requirements for appliances that incorporate an automatic cord reel and that have a second numeral IP rating;
o) clarified the appliance test criteria for the moisture resistance for appliances and parts of appliances with integral pins for insertion into socket-outlets;
p) introduced limits on the output voltage of an accessible safety extra-low voltage outlet or connector or Universal Serial Bus (USB) under abnormal operation conditions;
q) introduced requirements to cover optical radiation hazards;
r) introduced external communication software management items into normative Annex R;
s) revised external communication requirements in Table R.1 and Table R.2;
t) introduced in new normative Annex U cyber security requirements to avoid unauthorized access and the effects of transmission failures via remote communication through public networks.
This part is to be used in conjunction with the appropriate part 2 of IEC 60335. The parts 2 contain clauses to supplement or modify the corresponding clauses in this part to provide the relevant requirements for each type of appliance.
