(Main)Household and similar electrical appliances - Safety - Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40:2022)
Household and similar electrical appliances - Safety - Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40:2022)
This clause of Part 1 is replaced by the following.
This part of IEC 60335 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.
NOTE 101 A definition of ‘motor-compressor’ is given in IEC 60335-2-34, which includes the statement that the
term motor-compressor is used to designate either a hermetic motor-compressor or semi-hermetic motor-compressor.
NOTE 102 Requirements for containers intended for storage of the heated water included in sanitary hot water
heat pumps are, in addition, covered by IEC 60335-2-21.
This standard 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 standard 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.
NOTE 103 Annex HH provides informative requirements on competence of persons. Criteria for competence of
personnel for the purpose of certification schemes can be found in ISO 227121.
Unless specifications are covered by this standard, including the annexes, requirements for
refrigerating safety are covered by:
– ISO 5149-1:2014, ISO 5149-1:2014/AMD1:2015, and ISO 5149-1:2014/AMD2:2021,
– ISO 5149-2:2014 and ISO 5149-2:2014/AMD1:2020,
– ISO 5149-3:2014 and ISO 5149-3:2014/AMD1:2021.
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.
NOTE 104 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.
NOTE 105 This standard 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).
Sicherheit elektrischer Geräte für den Hausgebrauch und ähnliche Zwecke - Teil 2-40: Besondere Anforderungen für elektrisch betriebene Wärmepumpen, Klimageräte und Raumluft-Entfeuchter (IEC 60335-2-40:2022)
Appareils électrodomestiques et analogues - Sécurité - Partie 2-40: Règles particulières pour les pompes à chaleur électriques, les climatiseurs et les déshumidificateurs (IEC 60335-2-40:2022)
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).

Gospodinjski in podobni električni aparati - Varnost - 2-40. del: Posebne zahteve za električne toplotne črpalke, klimatske naprave in razvlažilnike zraka (IEC 60335-2-40:2022)
To točko 1. dela nadomešča naslednje besedilo.
Ta del standarda IEC 60335 obravnava varnost električnih toplotnih črpalk, toplotnih črpalk za gospodinjsko vročo vodo in klimatskih naprav z motornimi kompresorji in ventilatorskimi konvektorji voda/zrak, razvlažilnikov zraka (z motornimi kompresorji ali brez njih), termoelektričnih toplotnih črpalk ter delnih enot. Najvišja nazivna napetost teh aparatov ne sme presegati 300 V za enofazne aparate in 600 V za večfazne aparate.
Področje uporabe tega standarda zajema aparate, ki niso namenjeni za običajno gospodinjsko uporabo, vendar so lahko vir nevarnosti za javnost, kot so aparati, namenjeni za laično uporabo v trgovinah, lahki industriji in na kmetijah.
Navedeni aparati so lahko sestavljeni iz enega ali več tovarniško izdelanih sestavov. Če zajemajo več kot en sestav, se ločeni sestavi uporabljajo skupaj, zahteve pa temeljijo na uporabi združenih sestavov.
OPOMBA 101: Definicija »motornega kompresorja« je podana v standardu IEC 60335-2-34, ki vključuje izjavo, da se izraz motorni kompresor uporablja za označevanje motornega kompresorja hermetičnega ali polhermetičnega tipa.
OPOMBA 102: Zahteve za posode, namenjene za shranjevanje segrete vode, ki so del toplotnih črpalk za gospodinjsko vročo vodo, so zajete v standardu IEC 60335-2-21.
Ta standard ne obravnava hladilnih sredstev, razen tistih iz skupin A1, A2L, A2 in A3, kot so opredeljene v standardu ISO 817. Vnetljiva hladilna sredstva so omejena na tiste z molsko maso 42 kg/kmol ali več na podlagi formulacije v najslabšem primeru (WCF), kot je določeno v standardu ISO 817.
Ta standard v največji možni meri obravnava splošne nevarnosti, ki jih predstavljajo aparati in se pojavljajo pri njihovi običajni uporabi, ter predpostavlja, da namestitev, servisiranje, izločitev iz uporabe in odstranjevanje teh aparatov varno izvajajo kompetentne osebe, da se preprečijo nenamerni izpusti hladilnih sredstev. Vendar standard ne predpisuje meril za zagotavljanje kompetentnosti teh oseb med nameščanjem, servisiranjem in odstranjevanjem. Zahteve glede varnosti med odstranjevanjem niso določene v tem standardu.
OPOMBA 103: Dodatek HH vsebuje informativne zahteve za kompetentnost oseb. Merila za kompetentnost osebja za namene certifikacijskih shem so podana v standardu ISO 227121.
Če specifikacije, vključno z dodatki, v tem standardu niso zajete, so zahteve za varnost v zvezi s hlajenjem zajete v naslednjih standardih:
– ISO 5149-1:2014, ISO 5149-1:2014/AMD1:2015 in ISO 5149-1:2014/AMD2:2021;
– ISO 5149-2:2014 in ISO 5149-2:2014/AMD1:2020;
– ISO 5149-3:2014 in ISO 5149-3:2014/AMD1:2021.
Dodatni grelniki ali ukrepi za njihovo ločeno namestitev spadajo na področje uporabe tega standarda, vendar to velja le za grelnike, ki so zasnovani kot del aparata, pri čemer so krmilni elementi vgrajeni v aparat.
OPOMBA 104: Opozoriti je treba, da:
• so za aparate, ki so namenjeni za uporabo v vozilih ali na krovu ladij ali letal, morda potrebne dodatne zahteve;
• v številnih državah nacionalni zdravstveni organi, odgovorni za varstvo pri delu, ter nacionalni organi, odgovorni za shranjevanje, prevoz, stavbne konstrukcije in vgradnje, določajo dodatne zahteve.
OPOMBA 105: Ta standard se ne uporablja za:
• vlažilnike zraka, namenjene za uporabo z opremo za ogrevanje in hlajenje (IEC 60335-2-88);
• aparate, zasnovane izključno za industrijsko obdelavo;
• aparate, ki so namenjeni za uporabo na lokacijah, kjer veljajo posebne razmere, kot je prisotnost korozivne ali eksplozivne atmosfere (prah, hlapi ali plin).
