Household and similar electrical appliances - Safety - Part 2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40:2018)

This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric heat pumps, including sanitary hot
water heat pumps, air conditioners, and dehumidifiers incorporating motor-compressors
and hydronic fan coils units, their maximum rated voltages being not more than 250 V for
single phase appliances and 600 V for all other appliances. Partial units are within the scope
of this International Standard.
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.
The appliances referenced above may consist of one or more factory-made assemblies. If
provided in more than one assembly, the separate assemblies are to be 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 refrigerating safety are covered by ISO 5149-1, ISO 5149-2, and ISO 5149-3.
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 classification, A2L 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.
This standard specifies particular requirements for the use of flammable refrigerants. Unless
specifications are covered by this standard, including the annexes, requirements for
refrigerating safety are covered by ISO 5149.
The parts of ISO 5149 of particular concern to this standard are as follows:
• ISO 5149-1:2014, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 1: Definitions, classification and selection criteria.
• ISO 5149-2, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 2: Design, construction, testing, marking and documentation;
• ISO 5149-3:2014, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 3: Installation site.
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 103 Attention is drawn to the fact that
• for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
• for appliances subjected to pressure, additional requirements may 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 104 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 60335-2-40:2018)

Appareils électrodomestiques et analogues - Sécurité - Partie 2-40: Exigences particulières pour les pompes à chaleur électriques, les climatiseurs et les déshumidificateurs (IEC 60335-2-40:2018)

Gospodinjski in podobni električni aparati - Varnost - 2-40. del: Posebne zahteve za električne toplotne črpalke, klimatske naprave in sušilnike zraka (IEC 60335-2-40:2018)

To točko 1. dela nadomešča naslednje besedilo.
Ta del standarda IEC 60335 obravnava varnost električnih toplotnih črpalk, vključno s toplotnimi črpalkami za gospodinjsko vročo vodo, klimatskimi napravami, sušilniki zraka z motornimi kompresorji in ventilatorskimi konvektorji voda/zrak, katerih največja nazivna napetost ne presega 250 V za enofazne aparate in 600 V za vse druge aparate. Delne enote spadajo na področje uporabe tega mednarodnega standarda.
Na področje uporabe tega standarda spadajo aparati, 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 sestava ali več. Če zajemajo več kot en sestav, se morajo ločeni sestavi uporabljati 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 varnost v zvezi s hlajenjem so zajete v standardih ISO 5149-1, ISO 5149-2 in ISO 5149-3.
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 razvrstitvi standarda ISO 817, hladilna sredstva A2L pa 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 določa posebne zahteve za uporabo vnetljivih hladilnih sredstev. Če specifikacije, vključno z dodatki, v tem standardu niso zajete, so zahteve za varnost v zvezi s hlajenjem zajete v standardu ISO 5149.
Ta standard posebej obravnava naslednje dele standarda ISO 5149:
• ISO 5149-1:2014, Hladilni sistemi in toplotne črpalke – Varnostnotehnične in okoljevarstvene zahteve – 1. del: Definicije, razvrstitev in kriteriji za izbiro.
• ISO 5149-2, Hladilni sistemi in toplotne črpalke – Varnostnotehnične in okoljevarstvene zahteve – 2. del: Načrtovanje, izdelava, preskušanje, označevanje in dokumentacija;
• ISO 5149-3:2014, Hladilni sistemi in toplotne črpalke – Varnostnotehnične in okoljevarstvene zahteve – 3. del: Mesto postavitve.
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 kontrole vgrajene v aparat.
OPOMBA 103: Opozoriti je treba, da:
• so za aparate, ki so namenjeni za uporabo v vozilih ali na krovu ladij ali letal, morda potrebne dodatne zahteve;
• so za aparate, izpostavljene tlaku, 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 104: 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).
