Household and similar electrical appliances - Safety - Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers

Edition date: 2024-12-11
Cancelled
Available languages: Spanish, English, French
Summary: IEC 60335-2-40:2022 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units. Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase 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 laymen in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above can consist of one or more factory-made assemblies. If provided in more than one assembly, the separate assemblies are used together, and the requirements are based on the use of matched assemblies. This document does not take into account refrigerants other than group A1, A2L, A2 and A3 as defined by ISO 817. Flammable refrigerants are limited to those of a molar mass of more than or equal to 42 kg/kmol based on WCF (worst case formulation) as specified in ISO 817. As far as practical, this document deals with common hazards presented by appliances that are encountered in normal use and assumes that installation, servicing, decommissioning, and disposal are safely handled by competent persons and accidental release of refrigerants is avoided. However, it does not prescribe the criteria to ensure competence of persons during installation, servicing and disposal. Safety requirements during disposal are not specified in this standard. Supplementary heaters, or a provision for their separate installation, are within the scope of this standard, but only heaters which are designed as a part of the appliance package, the controls being incorporated in 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, for example, by the national health authorities responsible for the protection of labour and the national authorities responsible for storage, transportation, building constructions and installations.
This document does not apply to
- humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);
- appliances designed exclusively for industrial processing;
- 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 seventh edition cancels and replaces the sixth edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- Clause 1: added thermoelectric heat pumps to the scope and increased maximum rated voltage to 300 V for single phase appliances;
- Clause 7: revised requirements for marking on the appliance and packaging, including a symbol for minimum floor area and modifying the symbol for flammable refrigerants to include the safety group per ISO 817;
- Clause 11 and Clause 19: restructured for alignment with Part 1 and added requirements for supplementary air heaters;
- Clause 13 and Clause 16: revised requirement for leakage current for stationary class I motor-operated appliances;
- Clause 21: added requirements for particle foam material and revised requirements for transport testing;
- Clause 22: removed limit on the sum of refrigerant charges for appliances with multiple refrigerating systems, and revised requirements for avoiding ignition sources, leak detection systems, safety shut-off valves, and particle foam material;
- Clause 23: added requirements to avoid contact between wires and refrigerant piping;
- Clause 24
The content of the corrigendum 1 (2024-10) has been included in this copy.

L'IEC 60335-2-40:2022 traite de la sécurité des pompes à chaleur électriques, des pompes à chaleur pour production d'eau chaude sanitaire et des climatiseurs qui comportent des motocompresseurs ainsi que des ventiloconvecteurs hydroniques, des déshumidificateurs (avec ou sans motocompresseur), des pompes à chaleur thermoélectriques et des unités partielles. Leur tension assignée maximale n’est pas supérieure à 300 V pour les appareils monophasés et à 600 V pour les appareils multiphasés. Les appareils non destinés à un usage domestique normal, mais qui néanmoins peuvent constituer une source de danger pour le public, tels que les appareils destinés à être utilisés par des usagers non avertis dans des magasins, chez des artisans et dans des fermes, sont compris dans le domaine d'application de la présente norme. Les appareils indiqués ci-dessus peuvent consister en un ou plusieurs ensembles fabriqués en usine. Si les appareils sont fournis en plusieurs ensembles, les ensembles doivent être utilisés conjointement et les exigences correspondantes dépendent de l'utilisation des ensembles assortis. La présente norme ne couvre pas les fluides frigorigènes qui n'appartiennent pas aux groupes A1, A2L, A2 et A3 tels qu'ils sont définis par l’ISO 817. Les fluides frigorigènes inflammables se limitent à ceux dont la masse molaire est supérieure ou égale à 42 kg/kmol d'après la formule "la plus défavorable" (WCF, Worst Case Formulation) spécifiée dans l'ISO 817. Dans la mesure du possible, la présente norme traite des dangers courants engendrés par les appareils qui sont rencontrés dans le cadre d'une utilisation normale et elle suppose que l'installation, l'entretien, la mise hors service et l'élimination sont effectués en toute sécurité par des personnes compétentes et que le dégagement accidentel de fluides frigorigènes est évité. Toutefois, elle ne prescrit pas les critères qui permettent de garantir la compétence des personnes lors de l'installation, de l'entretien et de l'élimination. Les exigences de sécurité pendant l'élimination ne sont pas spécifiées dans la présente norme. Les dispositifs de chauffage supplémentaires (ou les dispositions concernant leur installation) sont couverts par le domaine d'application de la présente norme, mais uniquement les dispositifs de chauffage qui sont conçus en tant que partie de l'appareil, les commandes étant incorporées à l'appareil. L'attention est attirée sur le fait que
- pour les appareils destinés à être utilisés dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
- dans de nombreux pays, des exigences supplémentaires sont spécifiées par exemple par les organismes nationaux de la santé publique responsables de la protection des travailleurs et par les organismes nationaux responsables du stockage, du transport, de la construction des bâtiments et des installations.
La présente norme ne s'applique pas
- aux humidificateurs destinés à être utilisés avec des appareils de chauffage et de refroidissement (IEC 603352-88);
- aux appareils prévus exclusivement pour des usages industriels;
- aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz).
