IEC 60335-2-108:2024 deals with the safety of electrolysers that produce low viscosity, ionized liquids intended for use as detergent free wash water in appliances for household and similar purposes and which conform with the standards applicable to such appliances. It applies to electrolysers tested separately, under the most severe conditions that can be expected to occur in normal use, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances.
Examples of appliances that can contain electrolysers are:
- dishwashers (IEC 60335-2-5);
- washing machines (IEC 60335-2-7);
- appliances producing wash water for hygiene purposes.
This standard does not supersede the requirements of standards relevant to the particular appliance in which the electrolyser is used. However, if the electrolyser used complies with this standard, the tests for the electrolyser specified in the particular appliance standard can be unnecessary in the particular appliance or assembly. If the electrolyser control system is associated with the particular appliance control system, additional tests can be necessary on the final appliance. Guidance for additional requirements to be considered for inclusion in the end product standards for appliances that use electrolysers is given in informative Annex BB.
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 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).
This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the text has been aligned with IEC 60335-1:2020;
b) some notes have been converted to normative text (Clause 1, 22.012);
c) application of test probe 19 has been introduced (8.1.1, 20.2, B22.3, B22.4);
d) addition of external accessible surface temperatures (Clause 11).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1:2020 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.
