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 cl early 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 servi ces 
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 consolidated version of IEC  60335- 2-24 consi sts of the seventh  edition (20 10) 
[documents 61C/459/FDIS and 61C/461/RVD ] and its amendment 1 (201 2) [documents 
61C/506 /FDIS and 61C/509/RVD ]. It bears the edition number 7.1. 
The technical content is therefore identical to the base edition and its amendm ent and has 
been prepared for user convenience. A vertical line in the margin shows where the base 
publication has been modified by amendment 1. Additions and deletions are displayed in red, 
with deletions being struck through.

IEC 60335 -2-24:2010 +A1:2012  
This part of International Standard IEC  60335 has been prepared by subcommittee 61C: Household 
appliances for refrigeration, of IEC technical committee 61: Safety of household and similar 
electrical appliances.  
This seventh editio n cancels and replaces the sixth  edition published in 2002 including its 
Amendment 1 (2005) and A mendment 2 (2007 ). It constitutes a technical revision.  
The principal changes in this edition as compared with the previous  edition of IEC 60335 -2-24 are 
as follows (minor changes are not listed):  
– aligns the text with IEC 60335 -1, and its Amendments 1 and 2;  
– clarifies the term “household and similar use”  (1, 7.12);  
– updates marking requirements for supply terminals of battery operated appliances (7.6, 7.101);  
– introduces requirements  for app liances using transcritical refrigerant systems (3.112, 3.113, 
3.114, 3.115, 3.116, 7.1, 7.6, 7.12.1, 22.103, 24.1.4, 24.102);  
– introduces an enhanced flexing test (23.3);  
– introduces requirements for accessible glass panels (22.116);  
– clarifies tests for app liances using flammable refrigerants (22.107, Annex DD)  
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 establis hed on the basis of the fourth edition (2001) 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  electric refrigerating appliances, ice-
cream appliances and ice -makers.  
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 s tates "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.  
NOTE 3  The following print types are used:  
– requirements: in roman type;  
– test specifications: in italic type ; 
– notes: in smaller roman type.  
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the 
associated noun are also in bold.

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 t he 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 fam ily 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 
considerat ion 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 applic able 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 featur es 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.

Part 2 -24: Particular requirements for refrigerating appliances,  
ice-cream appliances and ice-makers  
 
  
1 Scope  
This clause of Part 1 is replaced by the following.  
This International Standard deals with the safety of the following appliances, their rated voltage  
being not more than 250 V for single -phase appliances, 480 V for other appliances and  24 V d.c. for 
appliances when battery operated.  
– refrigerating appliances  for household and similar use;  
– ice-makers incorporating a motor -compressor and ice-makers intended to be incorporated in 
frozen food storage compartments;  
– refrigerating appliances  and ice-makers for use in camping, touring caravans and boats for 
leisure purposes.  
These appliances may be operated from the mains, from a separate battery or operated either from 
the mains or from a separate battery.  
This standard also deals with the s afety of ice-cream appliances intended for household use, their 
rated voltage  being not more than 250 V for single -phase appliances and 480 V for other 
appliances.  
It also deals with compression -type appliances  for household and similar use, which use 
flam mable refrigerants . 
This standard does not cover features of the construction and operation of those refrigerating 
appliances  which are dealt with in other IEC standards.  
Refrigerating appliances not intended for normal household use but which nevertheless  may be a 
source of danger to the public, such as  
− refrigerating appliances  used in staff kitchen areas in shops, offices and other working 
environments , 
− refrigerating appliances used in farm houses and by clients in hotels, motels and other 
residential typ e environments , 
− refrigerating appliances used in bed and breakfast type environments , and 
− refrigerating appliances used  in catering and similar non -retail applications  
are within the scope of this standard.  
As far as is practicable, this standard deals wit h the common hazards presented by appliances that 
are encountered by all persons in and around the home. However, in general, it does not take into 
account  
– persons (including children) whose  
• physical, sensory or mental capabilities or  
• lack of experience and knowledge  
prevents them from using the appliance safely without supervision or instruction;  
– children playing with the appliance.  
NOTE 1  Attention is drawn to the fact that  
-17- 
 มอก. 2214- 25XX 
IEC 60335 -2-24:2010 +A1:2012  
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be 
necessary; 
– in many countries, additional requirements are specified by national health authorities, the national authorities 
responsible for the protection of labour, the national water supply authorities and similar author ities.  
NOTE 2  This standard does not apply to  
– appliances intended to be used in the open air; 
– appliances designed exclusively for industrial purposes;  
– appliances intended to be used in locations where special conditions prevail, such as the presence of a c orrosive or 
explosive atmosphere (dust, vapour or gas);  
– appliances incorporating a battery intended as a power supply for the refrigerating function;  
– appliances assembled on site by the installer;  
– appliances with remote motor -compressors;  
– motor -compressors  (IEC  60335- 2-34); 
– commercial dispensing appliances and vending appliances (IEC  60335- 2-75); 
– commercial refrigerators and freezers used for the display of food products, including beverages, for retail sale 
(IEC 60335- 2-89); 
– commercial ice -cream appliances .

up. 
Liquid containers located on the door are filled with a quantity of water to their full mark or, in the 
absence of a full mark, are completely filled.  
For appliances with only one door, this is opened through an angle of approximately 90° and a 
weight of 2,3 kg is placed 40 mm from the edge farthest from the hinge on top of the door.  
For appliances with more than one door, any two doors, in the most unfavourable combination, are 
opened through an angle of approximately 90°. The shelves of closed doors are not loaded. A 
weight of 2,3 kg is placed 40 mm from the edge farthest from the hinge on top of one of the open  
doors, chosen so as to give the most onerous test conditions.  
The test is repeated with the door or doors opened through an angle of approximately 180° or to the 
limit of the door stop, whichever results in the smaller angle of opening.  
Where appliances are provided with reversible doors, the test with the doors open to 180° or to the 
limit of the door stop, is repeated with the doors hinged on the other side in accordance with the 
instructions, if this will give a more unfavourable resul t.

After the tests, lampholders shall not have worked loose.  
Lampholders for a fluorescent lamp shall comply with the te st of 4.4.4 i) in IEC 60598 -1. 
22.102  Insulated wire heaters and their joints located in, and in integral contact with, thermal 
insulation shall be protected against entry of water.  
Compliance is checked by immersing three samples of the complete heating element in water 
containing approximately 1 % NaCl and having a temperature of 20 °C ± 5 °C for a period of 24  h. 
A voltage of 1 250 V is then applied for 15 min between the live part(s) of the heating element and 
the water.  
During the test, no breakdown shall occur.  
NOTE  Connections to electrical terminals are not considered as joints.  
22.103  Appliances employing a transcritical refrigeration system  shall in the high pressure side 
of the refrigeration system include a pressure relief device  on the compres sor or between the 
compressor and the gas cooler . There shall be no shut off devices or other components except

IEC 60335 -2-24:2010 +A1:2012  
The refrigeration system, including all components, shall withstand the pressures expected in 
normal and abnormal use and during standstill.  
Pressure testing has to be done on the complete refrigeration system, how ever it can be done 
separately for the low pressure side and for the high pressure side.  
Compliance is checked by inspection and by the following test:  
The pressure relief device is made inoperable and the test pressure is raised gradually  
− for the high pre ssure side , until a pressure not less than the minimum high side test pressure 
required in Table 101 of IEC 60335- 2-34 is reached, however not less than 3 times the design 
pressure ; 
− for the low pressure side , until a pressure not less than the minimum low side test pressure 
required in Table 102 of  IEC 60335 -2-34 is reached.  
For a refrigeration system with an intermediate pressure between high pressure side and low pressure side, all parts subjected to the in termediate pressure are considered to be on the low 
pressure side.  
The pressure is maintained for one minute and the parts under test shall show no leakage.  
NOTE The test is not carried out on motor -compressors complying with IEC 60335- 2-34. 
22.104  Appliances with two or more temperature control devices which control the same motor -
compressor shall not cause undue operation of the thermal motor -protector of the motor -
compressor.  
Compliance is checked by the following test.  
The appliance is operated a t rated voltage under normal operation  except that user adjustable 
temperature control devices are set to give cyclic operation.  
When steady conditions are established, and immediately after a breaking of the first control device 
the second control device is activated. The thermal motor -protector of the motor -compressor shall 
not operate.  
In the case of appliances where more than two control devices may act on a motor -compressor, the 
test is carried out separately with each combination of control devices.  
22.105  For mains -operated appliances which can also be battery operated, the battery circuit shall 
be insulated from live parts  by double insulation or reinforced insulation . 
Moreover, it shall not be possible to touch live parts  when making the connections  to the battery. 
This applies even if covers, or other parts, which have to be removed to make the connections are non-detachable parts.  
Compliance is checked by inspection and by the tests specified for double insulation  or 
reinforced insulation.  
22.106  The mass of refrigerant in compression- type appliances  which use flammable 
refrigerant  in their cooling system shall not exceed 150 g in each separate refrigerant circuit.  
Compliance is checked by inspection.  
22.107  Compression- type appliances  with a protected cooling system and which use flammable 
refrigerants  shall be constructed to avoid any fire or explosion hazard, in the event of leakage of 
the refrigerant from the cooling system.  
NOTE 1  Separate components such as thermostats  which contain less than 0,5 g of flammable gas are not considered 
liable to cause a fire or explosion hazard in the event of a leakage from the component itself. 
NOTE 2  Appliances with a protected cooling system are those  
– without any part of the cooling system insi de a food storage compartment;  
-40- 
 มอก. 2214-25XX 
IEC 60335 -2-24:2010 +A1:2012  
– where any part of the cooling system which is located inside a food storage compartment is constructed so that the 
refrigerant is contained within an enclosure with at least two layers of metallic materials separating the r efrigerant from 
the food storage compartment. Each layer shall have a thickness of at least 0,1 mm. The enclosure has no joints other 
than the bonded seams of the evaporator where the bonded seam has a width of at least 6 mm;  
– where any part of the cooling system which is located inside a food storage compartment has the refrigerant contained 
in an enclosure which itself is contained within a separate protective enclosure. If leakage from the containing 
enclosure occurs, the leaked refrigerant is contained within the protective enclosure and the appliance will not function 
as in normal use. The protective enclosure shall also withstand the test of 22.7. No critical point in the protective 
enclosure shall be located within the food storage compartment.  
NOTE  3 Separate compartments with a common air circuit are considered to be a single compartment.  
Compliance is checked by inspection and by the tests of 22.107.1, 22.107.2 and if necessary, 
22.107.3.  
NOTE 4  An appliance with a protected cooling system which, when tested, is found not to comply with the requirements 
specified for a protected cooling system, may be considered as having an unprotected cooling system if it is tested in 
accordance with 22.108 and found to comply with the requirements for an unprote cted cooling system . 
22.107.1 A leakage is simulated at the most critical point of the cooling system. For refrigerant 
circuits that do not meet the corrosion requirements of 22.107.3  a leak is also simulated at any 
point of the cooling circuit that is ne arest to an entry of a pipe or cable into a food storage 
compartment.  
NOTE 1  Critical points are only interconnecting joints between parts of the refrigerant circuit including the gasket of a 
semi -hermetic motor compressor. Aluminium to copper joints are a lso critical points unless they are protected against 
corrosion by a coating or sleeving that excludes oxygen. Welded telescopic joints of the motor -compressor  housing, the 
welding of the pipes through the motor -compressor housing and the welding of the hermetic glass to metal seals (fusite) 
are not considered to be pipework joints. To find the most critical point of the cooling system, it may be necessary to carry 
out more than one test.  
The method for simulating a leakage is to inject the refrigerant vapour through a capillary tube at 
the critical point. The capillary tube shall have a diameter of 0,7 mm ± 0,05 mm and a length 
between 2 m and 3 m.  
NOTE 2  Care should be taken that the installation of the capillary tube does not unduly influence the results of the test 
and that the foam does not enter the capillary tube during foaming. The capillary tube may need to be positioned before 
the appliance is foamed.  
During this test the appliance is tested with doors and lids closed, and is switched off or operated 
under  normal operation  at rated voltage , whichever gives the more unfavourable result.  
During a test in which the appliance is operated, gas injection is started at the same time as the 
appliance is first switched on.  
The quantity of refrigerant of the type indicated by the manufacturer to be injected is equal to 80 % 
of the nominal charge of the refrigerant ±1,5 g or the maximum which can be injected in one hour, 
whichever is the smaller.  
The quantity injected is taken from the vapour side of a gas bottle which shall contain enough liquid 
refrigerant to ensure that at the end of the test there is still liquid refrigerant left in the bottle.  
If a blend can fractionate, the test is carried out using the fraction that has  the smallest value of the 
lower explosive limit.  
The gas bottle is kept at a temperature of  
a) 32 °C ± 1 °C for leakage simulation on low -side pressure circuits;  
b) 70 °C ± 1 °C for leakage simulation on high- side pressure circuits.  
NOTE 3  The quantity of gas injected should preferably be measured by weighing the bottle.  
The concentration of leaked refrigerant is measured at least every 30 s from the beginning of the 
test and for at least 24 h after injection of the gas has stopped, inside and outside the food storage 
compartment, as close as possible to electrical components which, during normal operation , or 
abnormal operation, produce sparks or arcs.

NOTE 4  The instrument used for monitoring gas concentration, such as those which use infrared sensing techniques, 
should have a fast response, typically 2 s to 3 s and should not unduly influence the result of the test.  
NOTE 5  If gas chromatography is to be used, the gas sampling in confined areas should occur at a rate not exceeding 2 
ml every 30 s.  
NOTE 6  Other instruments are not precluded from being used provided that they do not unduly influence the results.  
The measured value shall not exceed 75 % of the lower explosive limit of the refrigerant specified in 
Table 102 and shall not exceed 50  % of the lower explosive limit of the refrigerant specified in Table

The surface to be tested is scratched at three different positions in a direction at right angles to the 
axis of the channel and at three different positions on the channel in a direction parallel to it. In the 
latter case, the length of the scratch shall be approximately 50 mm.  
The scratches shall not cross each other.  
The appropriate part of t he appliance shall withstand the test of 22.7, the test pressure being 
reduced by 50  %. 
22.107.3  If aluminium having a purity of less than 99,5 % according to ISO 209 is used in a 
protected cooling system that is embedded in thermal insulation, a sample of  the cooling system is 
subjected to the salt mist test of IEC 60068- 2-11 for a test duration of 48 h.   
After the test there shall be no sign of blistering, pitting or other active corrosion of the aluminium or 
its coating, if any.  
NOTE Aluminium with an ISO designation of Al 99,5 or an international registration record of 1050 A has a purity of

produce arcs or sparks during operation; nor to 
– intentionally weak parts that bec ome permanently open- circuited during the tests of Clause  19 
even if they produce arcs or sparks during operation.  
NOTE 1  Separate components such as thermostats  which contain less than 0,5 g of flammable gas are not considered 
liable to cause a fire or ex plosion hazard in the event of a leakage from the component itself.  
NOTE 2  Appliances with an unprotected cooling system are those where at least one part of the cooling system is placed 
inside a food storage compartment or those which do not comply with 22.107.

IEC 60079 series are also acceptable.  
NOTE 4  Changing of a lamp is not considered a potential explosion hazard, because the door or l id is open during this 
operation.  
Compliance is checked by inspection, by the appropriate tests of IEC  60079 -15 and by the following 
test. 
NOTE 5  The tests called up by Annex CC may be carried out using the stoichiometric concentration of the refrigerant 
used. However, apparatus which has been independently tested and found to comply with Annex CC using the gas 
specified for group IIA need not be tested.

The test is performed in a draught -free location with the appliance switched off or operated under 
conditions of normal operation at rated voltage, whichever gives the more unfavourable result.  
During a test in which the appliance is operated, gas injection is started at the same time as the 
appliance is first switched on.  
The test is carried out twice and is repeated a third time if one of the first tests gives more than 
40 % of the lower explosive limit.  
Through an appropriate orifice, 80 % of the nominal refrigerant charge ±1,5 g, in the vapour state is 
injected into a food storage compartment in a time not exceeding 10 min. The orifice is then closed. 
The injection shall be as close as possible to the centre of the back wall of the compa rtment at a 
distance from the top of the compartment approximately equal to one -third of the height of the 
compartment. Thirty minutes after the injection is completed, the door or lid is opened at a uniform 
rate in a time between 2 s and 4 s, to an angle of 90° or to the maximum possible, whichever is 
less.  
For appliances having more than one door or lid, the most unfavourable sequence or combination for opening the lids or doors is used.  
For appliances fitted with fan motors the test is done with the most  unfavourable combination of 
motor operation.  
The concentration of leaked refrigerant is measured at least every 30 s from the beginning of the test, at positions as close as possible to electrical components. However, it is not measured at the

accordance with the instructions for installation, with castors and rollers, if any, oriented, adjusted 
or blocked so as to prevent the appliance from moving. Locks, if any, on doors or lids are left 
unlocked.  
Doors and lids are closed for a period of 15 min.  
A force is then applied to a point, equivalent to an accessible inside point, of each appropriate door 
or lid of the appliance, at the midpoint of the edge farthest from the hinge axis in the direction 
perpend icular to the plane of the lid or door.  
The force shall be applied at a rate not exceeding 15 N/s and the lid or door shall open before the 
force exceeds 70 N.  
NOTE  1 The force may be applied by means of a spring balance with the aid of a suction pad if ne cessary, to the point on 
the outer surface of the door or lid which corresponds to the accessible inside point.  
NOTE  2 If the handle of the door or lid is at the mid- point of the edge farthest from the hinge axis, the force may be 
applied by means of a spr ing balance, to the handle. In this case, the value of the force required to open the door or lid 
from the inside may be determined by the proportional calculation relating to the distances of the handle and the 
accessible inside point from the hinge axis.  
22.113  Drawers which are only accessible after opening a door or lid shall not contain a free 
space.  
Compliance is checked by inspection and measurement.

NOTE 1  External door finishes made of glass t hat are covered by a transparent adhesive covering are considered to be 
accessible.  
For accessible glass panels  made from glass that shatters into small pieces when broken, 
compliance is checked by the following test, which is performed on two samples.  
Frames or other parts attached to the glass panel to be tested are removed and the glass is placed 
on a rigid horizontal flat surface.  
NOTE 2  The edges of the sample to be tested are contained within a frame of adhesive tape in such a manner that the 
broken pieces remain in place after breakage but without hindering expansion of the sample. 
The sample under test is broken by means of a test punch having a head with a mass of 75 g ± 5 g 
and a conical tungsten carbide tip with an angle of 60° ± 2°. The punch shall be positioned 
approximately 13 mm in from the longest edge of the glass at the midpoint of that edge. The punch 
is then hit by a hammer so that the glass breaks.  
A transparent mask of 50 mm x 50 mm is placed on the fractured glass except within a per ipheral 
margin of 25 mm from the edge of the sample and a semi -circular area having a radius of 100 mm 
from the point of impact.  
The assessment shall be undertaken on at least two areas of the sample, and the areas chosen 
shall contain the largest particle s. 
The number of crackfree particles within the mask are counted and for each assessment shall not be less than 40.  
NOTE 3  In the case of curved glass, plane pieces of the same material can be used for the test.  
For accessible glass panels made from glass that has enhanced mechanical strength , compliance

(normative)  
 
Locked -rotor test of fan motors  
 
The winding of a fan motor shall not reach excessive temperatures if the motor locks or fails to 
start.  
Compliance is checked by the following test.  
The fan and its motor are mounted on wood or similar material. The motor rotor is locked. Fan 
blades and motor  brackets are not removed.  
The motor is supplied at rated voltage . The supply circuit is given in Figure AA.1.  
The assembly is to operate under these conditions for 15 days (360 h) unless the protective 
device, if any, permanently opens the circuit prior to the expiration of that time. In this case, the 
test is discontinued.  
If the temperature of the motor windings stays lower than 90 °C, the test is discontinued when 
steady conditions are established.  
Temperatures are measured under conditions specified i n 11.3.  
During the test, the winding temperatures shall not exceed the values given in Table 8.  
72 h after the beginning of the test, the motor shall withstand the electric strength test of  16.3.  
A residual current device with a rated residual current of  30 mA is connected so as to disconnect 
the supply in the event of an excessive earth leakage current.  
At the end of the test, the leakage current is measured between the windings and the body at a 
voltage equal to twice the rated voltage . Its value shall no t exceed 2 mA.

Annex BB  
(informative)  
 
Method for accumulation of frost  
 
The ac cumulation of frost may be produced by the use of a device having a controllable heat source 
directed on a measured amount of water for the purpose of evaporating this water over a 
predetermined period with a minimum of extraneous heat loss to the cabinet of the refrigerating 
appliance . 
A convenient form of the apparatus would comprise a block enclosure of thermally insulating 
material having a vertical hole at its centre containing a lamp mounted on a bottom plug directly 
below an evaporating dish with a h igh thermal conductivity base and low thermal conductivity walls 
(see Figures BB.1 and BB.2).  
The device described above should be mounted at the geometric centre of the cabinet of the 
refrigerating appliance  and the electrical connection brought convenien tly to the outside so that 
the voltage applied may be varied and the power input measured with the door of the refrigerating 
appliance  in the closed position.  
Water is then introduced into the evaporating dish at the required rate through a length of small  
bore tube passing into the cabinet. A continuous flow is not necessary but the water should be 
injected at appropriate intervals.  
Provision should be made (for example in the control of the supply of electrical energy to the 
device) to ensure that the evaporation of water under normal conditions of use is capable of being 
maintained at a rate equal to 2 g of water per litre of gross cabinet volume per week.  
The electrical energy to the device should not be excessive, but shall be sufficient to ensure the complete evaporation of the water.  
The amount of frost to be accumulated prior to the start of the defrosting test should be based on this rate and on the time interval between two successive defrosts in accordance with the instructions.  
NOTE  For example, if the instructions recommend defrosting twice weekly, then a refrigerating appliance with a cabinet 
gross volume of 140 l will require:  
2 g ×  140 / 2 = 140 g of water  
The above rate may be exceeded in certain circumstances.  
The apparatus described has a m aximum evaporation rate of approximately 2 g/h when operating 
with an input of 4 W and with the water to be evaporated entering at cabinet temperature.
