Household and similar electrical appliances - Safety - Part 2-34: Particular requirements for motor-compressors

This clause of Part 1 is replaced by the following. This International Standard deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 480 V for other motorcompressors. This standard does not supersede the requirements of standards relevant to the particular appliance in which the motor-compressor is used. However, if the motor-compressor type used complies with this standard, the tests for the motor-compressor specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the motor-compressor control system is associated with the particular appliance control system, additional tests may be necessary on the final appliance. So far as is practical, this standard deals with the common hazards presented by motorcompressors used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account - the use of appliances by young children or infirm persons without supervision; - playing with the appliances by young children.

Sicherheit elektrischer Geräte für den Hausgebrauch und ähnliche Zwecke - Teil 2-34: Besondere Anforderungen für Motorverdichter

Appareils électrodomestiques et analogues - Sécurité - Partie 2-34: Règles particulières pour les motocompresseurs

La CEI 60335-2-34:2012 traite de la sécurité des motocompresseurs étanches (de type hermétique et hermétique accessible) et, le cas échéant, de leurs systèmes de protection et de commande, qui sont destinés à être utilisés sur les appareils électrodomestiques et analogues et qui sont conformes aux normes applicables à de tels matériels. Elle s'applique aux motocompresseurs soumis à essai séparément, dans les conditions les plus sévères qui peuvent se produire en usage normal, la tension assignée n'étant pas supérieure à 250 V pour les motocompresseurs monophasés et à 480 V pour les autres motocompresseurs. Comme exemples d'appareils équipés de motocompresseurs, on peut citer: - les réfrigérateurs, congélateurs et fabriques de glace (CEI 60335-2-24); - les climatiseurs, pompes à chaleur électriques et déshumidificateurs (CEI 60335-2-40); - les distributeurs commerciaux avec ou sans moyen de paiement (CEI 60335-2-75), - les ensembles montés en usine pour le transfert de chaleur dans des applications de réfrigération, de climatisation ou de chauffage, ou toute combinaison de ces fonctions. La présente norme ne remplace pas les exigences des normes applicables aux appareils dans lesquels des motocompresseurs sont utilisés. Toutefois, si le type de motocompresseur utilisé est conforme à la présente norme, il est possible que les essais pour les motocompresseurs spécifiés dans les normes relatives aux appareils particuliers n'aient pas besoin d'être effectués sur l'appareil ou l'ensemble particulier. Si le dispositif de commande du motocompresseur est associé au dispositif de commande de l'appareil particulier, des essais complémentaires peuvent être nécessaires sur l'appareil final. Mots clé: motocompresseur, hermétique, hermétique accessible

Gospodinjski in podobni električni aparati - Varnost - 2-34. del: Posebne zahteve za motorne kompresorje (IEC 60335-2-34:2012)

To točko 1. dela nadomešča naslednje besedilo. Ta mednarodni standard obravnava varnost zatesnjenih motornih kompresorjev (hermetičnega ali polhermetičnega tipa) ter njihovih zaščitnih in nadzornih sistemov, če so nameščeni, ki so namenjeni za uporabo v opremi za gospodinjstvo in podobne namene ter ki so v skladu s standardi, ki veljajo za takšno opremo. Velja za motorne kompresorje, preskušene ločeno, v najhujših razmerah, ki se lahko pojavijo pri običajni rabi, pri čemer nazivna napetost enofaznih motorskih kompresorjev ne presega 250 V in nazivna napetost drugih motornih kompresorjev ne presega 480 V. Ta standard ne nadomešča zahtev posameznih standardov, ki zadevajo določene aparate, v katerih je motorni kompresor. Vendar pa v primeru, da uporabljeni tip motorskega kompresorja v zadevnem aparatu ali sestavu ustreza temu standardu, ni potrebno opraviti preskusov za motorni kompresor, navedenih v zadevnem standardu za aparat. Če je kontrolni sistem motornega kompresorja povezan s kontrolnim sistemom zadevne naprave, bodo morda potrebni dodatni preskusi na končnem aparatu. Ta standard v največji možni meri obravnava splošne nevarnosti, ki jih predstavljajo motorski kompresorji v aparatih, s katerimi se srečujejo osebe doma in v okolici doma. Vendar na splošno ne vključuje primerov, ko aparate brez nadzora uporabljajo majhni otroci ali onemogle osebe oziroma ko se otroci igrajo z napravami.

Part 2-34: Particular requirements for motor-compressors
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This part of International Standard IEC 60335 has been prepared by subcommittee 61C:

Safety of refrigeration appliances for household and commercial use, of IEC technical

committee 61: Safety of household and similar electrical appliances.

This fifth edition cancels and replaces the fourth edition published in 2002 including its

Amendment 1 (2004) and its amendment 2 (2008). It constitutes a technical revision.

The principal changes in this edition as compared with the fourth edition of IEC 60335-2-34

The text of this part of IEC 60335 is based on the following documents:
FDIS Report on voting
61C/508/FDIS 61C/517/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its

amendments. It was established on the basis of the fifth edition (2010) of that standard.

NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.

This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to

convert that publication into the IEC standard: Safety requirements for electrical motor-

compressors.

When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies

as far as is reasonable. When this standard states "addition", "modification" or "replacement",

the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;

– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including

those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.

INTRODUCTION

It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions It also covers abnormal

situations that can be expected in practice and takes into account the way in which

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that

there is compatibility with the wiring rules when the appliance is connected to the supply

mains. However, national wiring rules may differ.

If an appliance within the scope of this standard also incorporates functions that are covered

by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as

far as is reasonable. If applicable, the influence of one function on the other is taken into

account.

When a part 2 standard does not include additional requirements to cover hazards dealt with

in Part 1, Part 1 applies.

NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is

not necessary to specify particular requirements for the appliance in question over and above the general

requirements.

This standard is a product family standard dealing with the safety of appliances and takes

precedence over horizontal and generic standards covering the same subject.

NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into

consideration when developing the general and particular requirements for the IEC 60335 series of standards. For

example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as

ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.

An appliance that complies with the text of this standard will not necessarily be considered to

comply with the safety principles of the standard if, when examined and tested, it is found to

have other features that impair the level of safety covered by these requirements.

An appliance employing materials or having forms of construction differing from those detailed

in the requirements of this standard may be examined and tested according to the intent of

the requirements and, if found to be substantially equivalent, may be considered to comply

with the standard.

For motor-compressors, testing in accordance with this standard is an option and cannot be

required as a precondition for testing the complete appliance, for example by reference in

Clause 24 of a part 2 of IEC 60335. However, testing of the appliance should be reduced if an

incorporated motor-compressor including its protection system or control system, if any,

complies with this standard.
If testing of the motor-compressor includes testing in accordance with Annex AA,

temperatures of the motor-compressor windings, housing and other parts related to the

motor-compressor, such as terminals, internal wiring and insulating materials, are not

measured when the complete appliance in which the motor-compressor is used is tested.

These requirements apply to sealed (hermetic and semi-hermetic type) motor-compressors

with their associated starting, cooling capacity control and protection systems, tested

separately under the most severe conditions of the refrigerating system operation which,

within reasonable limits, could occur in the applications for which they are used.

– 8 – 60335-2-34 © IEC:2012

In particular, the construction detail inspection and locked-rotor testing may be done

separately on the motor-compressor, thereby eliminating the need for inspection and testing

when the motor-compressor is applied to many different appliances and factory-built

assemblies.

Operational tests may also be conducted on the motor-compressor separately in certain

circumstances. The specification for this type testing is provided in Annex AA. However, the

tests of the existing standards relevant to the given kind of application, such as IEC 60335-2-

24 and IEC 60335-2-40, may need to be conducted on the final application and used as the

final determination of acceptability.

Part 2-34: Particular requirements for motor-compressors
1 Scope
This clause of Part 1 is replaced by the following.

This International Standard deals with the safety of sealed (hermetic and semi-hermetic type)

motor-compressors, their protection and control systems, if any, which are intended for use

in equipment for household and similar purposes and which conform with the standards

applicable to such equipment. It applies to motor-compressors tested separately, under the

most severe conditions that may be expected to occur in normal use, their rated voltage

being not more than 250 V for single-phase motor-compressors and 480 V for other motor-

compressors.
NOTE 101 Examples of equipment which contain motor-compressors are
– refrigerators, food freezers and ice makers (IEC 60335-2-24);
– air-conditioners, electric heat pumps and dehumidifiers (IEC 60335-2-40);
– commercial dispensing appliances and vending machines (IEC 60335-2-75);

– factory-built assemblies for transferring heat in applications for refrigerating, air-conditioning or heating

purposes or a combination of such purposes.

This standard does not supersede the requirements of standards relevant to the particular

appliance in which the motor-compressor is used. However, if the motor-compressor type

used complies with this standard, the tests for the motor-compressor specified in the

particular appliance standard may not need to be made in the particular appliance or

assembly. If the motor-compressor control system is associated with the particular

appliance control system, additional tests may be necessary on the final appliance.

So far as is practical, this standard deals with the common hazards presented by motor-

compressors used in appliances which are encountered by all persons in and around the

home. However, it does not in general take into account
– the use of appliances by young children or infirm persons without supervision;
– playing with the appliances by young children.
NOTE 102 Attention is drawn to the fact that

– for motor-compressors intended to be used in appliances in vehicles or on board ships, additional require-

ments may be necessary;

– in many countries, additional requirements are specified by the national health authorities, the national

authorities responsible for the protection of labour and similar authorities.
NOTE 103 This standard does not apply to
– motor-compressors designed exclusively for industrial purposes;

– motor-compressors used in 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).

NOTE 104 If motor-compressors for refrigerant R-744 used in appliances with a transcritical refrigeration

system are equipped with pre
