Part 2-54: Particular requirements for surface-cleaning appliances
for household use employing liquids or steam

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 consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
IEC 60335-2-54 edition 5.1 contains the fifth edition (2015-02) [documents 61/6672/FDIS and

NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 publications, basic safety publications and group safety publications 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.
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric cleaning appliances for household use
that are intended for cleaning surfaces by using liquid cleansing agents or steam, their rated
voltage being not more than 250 V including direct current (DC) supplied appliances and
battery-operated appliances. It also covers wallpaper strippers and surface cleaning
appliances incorporating heating elements or means for pressurizing the liquid container.
As far as is practicable, this standard deals with 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.
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 by the national health authorities,
the national authorities responsible for the protection of labour, and similar authorities.
This standard does not apply to
– floor treatment and wet scrubbing machines (IEC 60335-2-10);
– cleaning appliances that are permanently fixed to a building;
– cleaning appliances covered by IEC 60335-2-79, namely those having a
• pressure exceeding 2,5 MPa;
• pressurised volume over 5 l;
• product of pressure (in MPa) and container volume (in l) exceeding 5;
• liquid temperature exceeding 160 °C;
• rated power input exceeding 3 500 W;
– cleaning appliances intended for commercial or industrial use;
– 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);
– fabric steamers (IEC 60335-2-85).

of 50 mm and the edges of the longer sides rounded with a radius of 1 mm. The axis of the
hose is positioned at right angles to the longer sides of the plates. The plates are placed at a
distance of approximately 350 mm from one end of the hose.
The steel plates are pressed together at a rate of 50 mm/min ± 5 mm/min until the applied force
is 1,5 kN. The force is then released and the electric strength test of 16.3 is carried out between
the conductors connected together and the saline solution.
21.102 Current-carrying hoses shall be resistant to abrasion.
Compliance is checked by the following test.
One end of the hose is attached to the connecting rod of the crank mechanism shown in
Figure 102. The crank rotates at 30 r/min resulting in the end of the hose moving horizontally
backwards and forwards over a distance of 300 mm.
The hose is supported by a rotating smooth roller over which a belt of abrasive cloth moves at
a speed of 0,1 m/min. The abrasive is corundum grit, size P100 as specified in ISO 6344-2. A
mass of 1 kg is suspended from the other end of the hose, which is guided to avoid rotation. In
the lowest position, the mass has a maximum distance of 600 mm from the centre of the roller.
The test is carried out for 100 revolutions of the crank.
After the test, basic insulation shall not be exposed and the electric strength test of 16.3 is
carried out between the conductors connected together and the saline solution.
21.103 Current-carrying hoses shall be resistant to flexing.
Compliance is checked by the following test.
The end of the hose intended to be connected to the motorized cleaning head is attached to
the pivoting arm of the test equipment shown in Figure 103. The distance between the pivot
axis of the arm and the point where the hose enters the rigid part is 300 mm ± 5 mm. The arm
can be raised from the horizontal position by an angle of 40° ± 1°. A mass of 5 kg is suspended
from the other end of the hose or from a convenient point along the hose so that when the arm
is in the horizontal position, the mass is supported and there is no tension on the hose.
NOTE It can be necessary to reposition the mass during the test.
The mass slides against an inclined plate so that the maximum deflection of the hose is 3°. The
arm is raised and lowered by means of a crank that rotates at a speed of 10 r/min ± 1 r/min.
The test is carried out for 1 250 revolutions of the crank after which the fixed end of the hose
is turned through 90° and the test continued for a further 1 250 revolutions. The test is repeated
in each of the other two 90° positions.
If the hose ruptures before 5 000 revolutions of the crank, the flexing is terminated.
After the test, the hose shall withstand the electric strength test of 16.3.
21.104 Current-carrying hoses shall be resistant to torsion.
Compliance is checked by the following test.
One end of the hose is held in a horizontal position with the remainder of the hose freely
suspended. This end is rotated in cycles, each cycle consisting of five turns in one direction
and five turns in the opposite direction, at a rate of 10 r/min.
The test is carried out for 1 000 cycles.
After the test, the hose shall withstand the electric strength test of 16.3 and shall not be
damaged to such an extent that compliance with this standard is impaired.
21.105 Current-carrying hoses shall be resistant to low temperatures.
Compliance is checked by the following test.
A 600 mm length of hose is bent as shown in Figure 104 and the ends are tied together over a
length of 25 mm. The hose is then placed for 2 h in a cabinet having a temperature of
−15 °C ± 2 °C. Immediately after the hose is removed from the cabinet, it is flexed three times,
as shown in Figure 105, at a rate of one flexing per second.
The test is carried out three times.
There shall be no cracks or breaks in the hose and it shall withstand the electric strength test
of 16.3. Any discolouration is neglected.
22 Construction
This clause of Part 1 is applicable except as follows.
22.6 Addition:
A drain hole that is needed to comply with the standard shall be at least 5 mm in diameter or
in area with a width of at least 3 mm. Holes that do not meet these dimensions are
20 mm
considered to be blocked when determining compliance.
22.7 Replacement:
Pressurised appliances and instantaneous steam cleaners shall incorporate adequate
safeguards against the risk of excessive pressure.
If jets of steam or liquids are emitted through protective devices, the electrical insulation shall
not be affected or the user exposed to a hazard.
Compliance is checked by inspection and by the following tests.
The maximum pressure occurring during the test of Clause 11 is measured. All pressure-
regulating devices that operated during the test are rendered inoperative and the pressure
measured again. The pressure shall not exceed three times the pressure measured during the
test in Clause 11. Any pressure-limiting protective device is then rendered inoperative and the
pressure in the boiler is raised hydraulically to five times the pressure measured originally or
twice the pressure measured with the pressure-regulating device rendered inoperative,
whichever is higher. The pressure is maintained for a period of 60 s. There shall be no leakage
from the boiler.
Steam cleaners incorporating hoses and having a device regulating the steam supply are
operated as specified in Clause 11, but with all pressure-regulating devices operating during
the test of Clause 11 rendered inoperative. The steam outlet is sealed and the device regulating
the steam supply is opened. There shall be no leakage from the hose except at an intentionally
weak place within the enclosure of the boiler. If this occurs, the test is repeated on another
appliance that shall also leak in the same way.
The steam outlet of instantaneous steam cleaners is sealed and the pressure in the water
container is raised hydraulically until the pressure-limiting protective device operates. The
pressure shall not exceed three times the pressure measured during the test of Clause 11. The
outlet of the protective device is then sealed and the pressure is further raised to twice the
previous value. The pre

Part 2-54: Particular requirements for surface-cleaning appliances
for household use employing liquids or steam

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.
IEC 60335-2-54 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This fifth edition cancels and replaces the fourth edition published in 2008, Amendment 1: 2015
and Amendment 2: 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, 15.2, 21.103, 21.105, 22.103);
c) addition of external accessible surface temperature limits (3.6.102, 3.6.103, 7.1, 11.3, 11.8)
d) exception for hand-held appliances (20.1);

The text of this International Standard is based on the following documents:
Draft Report on voting
61/6672/FDIS 61/6749/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/standardsdev/publications.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for surface-cleaning appliances
for household use employing liquids or steam.
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.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small 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.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 12 months or later than 36 months from the date of publication.

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 publications, basic safety publications and group safety publications 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.
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

SAFETY –
Part 2-54: Particular requirements for surface-cleaning appliances
for household use employing liquids or steam

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric cleaning appliances for household use
that are intended for cleaning surfaces by using liquid cleansing agents or steam, their rated
voltage being not more than 250 V including direct current (DC) supplied appliances and
battery-operated appliances. It also covers wallpaper strippers and surface cleaning
appliances incorporating heating elements or means for pressurizing the liquid container.
As far as is practicable, this standard deals with 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.
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 by the national health authorities,
the national authorities responsible for the protection of labour, and similar authorities.
This standard does not apply to
– floor treatment and wet scrubbing machines (IEC 60335-2-10);
– cleaning appliances that are permanently fixed to a building;
– cleaning appliances covered by IEC 60335-2-79, namely those having a
• pressure exceeding 2,5 MPa;
• pressurised volume over 5 l;
• product of pressure (in MPa) and container volume (in l) exceeding 5;
• liquid temperature exceeding 160 °C;
• rated power input exceeding 3 500 W;
– cleaning appliances intended for commercial or industrial use;

These tests are carried out three times.
NOTE 101 It can be necessary to conduct the test in various positions to determine the most unfavourable position.
21.101 Current-carrying hoses shall be resistant to crushing.
Compliance is checked by the following test.

– 16 – IEC 60335-2-54:2022 © IEC 2022
The hose is placed between two parallel steel plates each having a length of 100 mm, a width
of 50 mm and the edges of the longer sides rounded with a radius of 1 mm. The axis of the
hose is positioned at right angles to the longer sides of the plates. The plates are placed at a
distance of approximately 350 mm from one end of the hose.
The steel plates are pressed together at a rate of 50 mm/min ± 5 mm/min until the applied force
is 1,5 kN. The force is then released and the electric strength test of 16.3 is carried out between
the conductors connected together and the saline solution.
21.102 Current-carrying hoses shall be resistant to abrasion.
Compliance is checked by the following test.
One end of the hose is attached to the connecting rod of the crank mechanism shown in
Figure 102. The crank rotates at 30 r/min resulting in the end of the hose moving horizontally
backwards and forwards over a distance of 300 mm.
The hose is supported by a rotating smooth roller over which a belt of abrasive cloth moves at
a speed of 0,1 m/min. The abrasive is corundum grit, size P100 as specified in ISO 6344-2. A
mass of 1 kg is suspended from the other end of the hose, which is guided to avoid rotation. In
the lowest position, the mass has a maximum distance of 600 mm from the centre of the roller.
The test is carried out for 100 revolutions of the crank.
After the test, basic insulation shall not be exposed and the electric strength test of 16.3 is
carried out between the conductors connected together and the saline solution.
21.103 Current-carrying hoses shall be resistant to flexing.
Compliance is checked by the following test.
The end of the hose intended to be connected to the motorized cleaning head is attached to
the pivoting arm of the test equipment shown in Figure 103. The distance between the pivot
axis of the arm and the point where the hose enters the rigid part is 300 mm ± 5 mm. The arm
can be raised from the horizontal position by an angle of 40° ± 1°. A mass of 5 kg is suspended
from the other end of the hose or from a convenient point along the hose so that when the arm
is in the horizontal position, the mass is supported and there is no tension on the hose.
NOTE It can be necessary to reposition the mass during the test.
The mass slides against an inclined plate so that the maximum deflection of the hose is 3°. The
arm is raised and lowered by means of a crank that rotates at a speed of 10 r/min ± 1 r/min.
The test is carried out for 1 250 revolutions of the crank after which the fixed end of the hose
is turned through 90° and the test continued for a further 1 250 revolutions. The test is repeated
in each of the other two 90° positions.
If the hose ruptures before 5 000 revolutions of the crank, the flexing is terminated.
After the test, the hose shall withstand the electric strength test of 16.3.
21.104 Current-carrying hoses shall be resistant to torsion.
Compliance is checked by the following test.

One end of the hose is held in a horizontal position with the remainder of the hose freely
suspended. This end is rotated in cycles, each cycle consisting of five turns in one direction
and five turns in the opposite direction, at a rate of 10 r/min.
The test is carried out for 1 000 cycles.
After the test, the hose shall withstand the electric strength test of 16.3 and shall not be
damaged to such an extent that compliance with this standard is impaired.
21.105 Current-carrying hoses shall be resistant to low temperatures.
Compliance is checked by the following test.
A 600 mm length of hose is bent as shown in Figure 104 and the ends are tied together over a
length of 25 mm. The hose is then placed for 2 h in a cabinet having a temperature of
−15 °C ± 2 °C. Immediately after the hose is removed from the cabinet, it is flexed three times,
as shown in Figure 105, at a rate of one flexing per second.
The test is carried out three times.
There shall be no cracks or breaks in the hose and it shall withstand the electric strength test
of 16.3. Any discolouration is neglected.
