Overview

IEC 60335-2-119:2021 is an international safety standard for commercial vacuum packaging appliances used for food preservation. It applies to electric chamber and non-chamber vacuum packaging machines (including those with film‑sealing functions) used in commercial settings - e.g., restaurants, canteens, hospitals, bakeries and butcheries. The standard covers appliances with rated voltages up to 250 V for single‑phase units and 480 V for other appliances. It is not intended for household devices and must be used together with IEC 60335-1 (general safety requirements).

Key topics and requirements

This Part 2 supplements IEC 60335-1 and addresses particular hazards and test requirements specific to vacuum packaging equipment. Major technical topics include:

• Scope and applicability - definition of covered appliances, exclusions (household appliances, battery‑operated units, machines injecting inert gas with oxygen >21 %, or use in explosive/corrosive atmospheres).
• Electrical safety - protection against access to live parts, leakage current, electric strength (including tests at operating temperature), transient overvoltages and power input/current requirements.
• Thermal and heating controls - requirements for heating and sealing functions to reduce fire and burn risks.
• Mechanical safety - stability, mechanical strength, overload protection, and protection during abnormal operation.
• Hygiene and food safety - construction and materials, cleaning/drying resilience and methods to control contamination (the standard explicitly deals with hygiene aspects).
• Marking & instructions - safety labeling, user instructions and warnings tailored to commercial use.
• Environmental resistance - moisture resistance, rusting, radiation/toxicity considerations and resistance to special operating conditions.
• Testing and annexes - endurance, splash and mechanical testing, and an informative annex (Annex AA) on calculating gas concentration.

The standard also highlights that additional national requirements may apply (pressure vessels, health and labour authorities, national water supply rules).

Applications and users

IEC 60335-2-119 is used by:

• Manufacturers and designers of commercial vacuum packaging appliances to ensure product safety and market acceptance.
• Test laboratories and certification bodies for type testing and conformity assessment.
• Procurement teams in foodservice, hospitality, healthcare and food processing who require compliant equipment.
• Regulators and safety engineers assessing workplace safety and compliance with electrical and hygiene rules.

Compliance reduces electrical, mechanical, thermal and hygiene-related risks in commercial food‑preservation operations.

Related standards

• IEC 60335-1 - General requirements for safety of household and similar electrical appliances (mandatory companion document).
• IEC 60335-2-45 - Particular requirements for vacuum packaging appliances for household use (for household product differentiation).
• National wiring rules (e.g., IEC 60364) and country‑specific regulations for pressure vessels, health and labour authorities may impose additional requirements.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC

IEC 60335-2-119 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
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 in the IEC 60335 series, published 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 commercial vacuum
packaging appliances.
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

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 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 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.

For all other appliances, the bowl is placed on the same plane where the appliance is placed
and is moved around in such a way as to splash the sides of the appliance from all directions.
During the test, the water pressure is so regulated that the water splashes up 100 mm above
the bottom of the bowl. The appliance shall not be hit by the direct jet.
15.2 Addition:
Compliance is also checked by the tests of 15.2.101 and 15.2.102.
15.2.101 For all appliances, 0,5 l of the spillage solution is poured rapidly over the top of the
appliance in the most unfavourable way so that the spillage solution also flows over the surfaces
of the appliance that incorporate controls and other places where it may penetrate the appliance
enclosure, the controls being placed in the most unfavourable position. The controls are then
operated through their working range, this operation being repeated after 5 min.

© IEC 2025
For chamber vacuum packing appliances, the test is carried out with the lid placed in the fully
open or fully closed position, whichever is likely to be the most unfavourable.
For appliances having a working surface, the test is repeated with the appliance tilted at an
angle of 2° in relation to the position of normal use in the direction which is likely to be the most
unfavourable.
The lid of top loading appliances is considered as a working surface if it is flat enough to put
something on.
Additional action, like drying of tested areas, may be needed to ensure that first pouring test
does not impact the result of the second one.
The appliance shall withstand the electric strength test of 16.3 and inspection shall show that
there is no trace of water on insulation that could result in a reduction of clearances and
creepage distances below the values specified in Clause 29.
15.2.102 Parts liable to be cleaned are wiped in turn, with a sponge, having dimensions
approximately 150 mm × 75 mm × 50 mm, saturated with water containing approximately 1 %
NaCl. The sponge is applied without appreciable force for approximately 10 s to each surface.
After each cleaning test, all residues are removed, and the appliance is dried to ensure that a
cleaning test is not impacted by a preceding one.
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on the insulation that could result in a reduction of clearances
and creepage distances below the values specified in Clause 29.
15.101 Packaging appliances shall be constructed so that suction of liquid does not impair
electrical insulation. This requirement does not apply to parts operating at safety extra-low
voltage.
Compliance is checked by the following tests.
For vacuum packaging appliances, one plastic channelled bag with dimensions 20 cm ×
30 cm filled with water containing approximately 1 % NaCl, at a temperature of 30 °C ± 0,5 °C,
is positioned so that the surface of the water is at the same level as the suction opening of the
appliance. Then the vacuum and sealing process is performed.
NOTE Channelled vacuum bags are vacuum bags specifically designed to allow air to escape easily from the bag.
For chamber vacuum packaging appliances, a quantity of water at a temperature of 30 °C
± 0,5 °C containing approximately 1 % NaCl and equal to 10 % of the volume of the vacuum
chamber is poured in the chamber. Then the vacuum and sealing process is performed.
The appliance shall then withstand the electric strength test of 16.3 and inspection shall show
that there is no trace of water on the insulation that could result in a reduction of clearances
and creepage distances below the values specified in Clause 29.

Annex AA
(informative)
Method for calculating the gas concentration
AA.1 Calculation of gas concentration
The following information shall be considered by the manufacturer. If the manufacturer does
not clearly specify and limit the size of the working space and the gas cylinder, the following
information shall be given in the instructions.
AA.2 Calculations for safe operation with protective gases (modified
atmosphere packaging)
AA.2.1 Guidance for the evaluation of ventilation requirements
The ventilation requirements depend on numerous factors such as location, type of gas and
possible leaks. Ventilation can be natural or forced ventilation. The normal index to be
considered is the number of air exchanges per hour.
Typically, the required number of air exchanges can be calculated based on an estimated gas
outlet or leakage rate of a machine in operation. A homogeneous gas distribution is assumed,
and the following formula is applied:
-nt×
Le× 1-
( )
C =
t
Vn×
r
where
C is the gas concentration at time t;
t
L is the gas flow [m /h];
V is the volume of the room [m ];
r
n are the air exchanges per hour;
t is the time of gas flow in hours.
For long periods of time (t with a tendency towards infinity), the following applies:
L
C∞=
Vn ×
r
Since this calculation refers to continuous gas discharge, the goal shall be to keep the oxygen
concentration between 20 % and 22 % by sufficient ventilation (air exchanges).
Natural air ventilation rates can be evaluated as follows:
• In above-ground locations without special ventilation openings, natural ventilation generally
achieves one air exchange per hour. However, this does not apply to buildings in which the
windows are gas tight.
• If special ventilation openings are available, up to two air changes per hour can be assumed.
• For underground rooms with small windows, an average natural air exchange rate of 0,4 per
hour can be assumed.
REDLINE VERSION – 18 – IEC 60335-2-119:2021+AMD1:2025 CSV
© IEC 2025
• For more than 2 air exchanges per hour a forced ventilation system is required.
Special building regulations may recommend or require a specific number of air exchanges per
hour for different conditions, i.e. 5, 10, 20.
In case of doubt on required air exchanges, contact an appropriately licensed ventilation
technician or refer to building regulations concerning the specific installation.
AA.2.2 Calculation for the use of gas cylinders in rooms
This requirement deals with the worst-case scenario, where the entire contents of a gas cylinder
or storage container leak into the room immediately as a result of a catastrophic failure, such
as a burst hose, a leaking pipe connection or a permanently open gas valve. The trigger for
such an event could be the failure of a regulator.
In the event of such a catastrophic scenario, mastering the situation is initially more important
than trying to restore an atmosphere suitable as a working environment. For this reason, an
oxygen concentration of 25 % is acceptable in the short term.
The calculation can also be performed for oxygen replacing gases. In this case, it is essential
that the oxygen concentration shall not fall below 18 %.
The remaining oxygen concentration in the room can be calculated as follows:
100 ×V
O
C =
OX
V
r
where
C is the remaining oxygen concentration [%];
OX
V is the volume of oxygen in the room [m ];
O
V is the volume of the room [m ] subtracting the volume of all large objects.
r
For gas cylinders with gases replacing oxygen the following applies:
V= 0,21× VV- m of O
( )
O rtg 2
where
V is the gas volume in the full gas cylinder at 15 °C and 101,3 kPa.
tg
For gas cylinders with oxygen, the following applies:
V = 0,21× VV- +V m of O
( )
O r tg OG 2
where
V is the oxygen volume in the full gas cylinder at 15 °C and 101,3 kPa.
OG
For pure oxygen, V = V
OG tg
For a mixture of x % O in inert gas, the following applies:
© IEC 2025
x
V= ×V
OG tg
If, according to calculations, the contents of an oxygen cylinder leaking into the room would
result in an oxygen concentration of over 25 %, there are four possibilities:
a) place the gas cylinder and the packaging machine in a larger room to ensure an oxygen
concentration lower than 25 %,
b) use a smaller gas cylinder with a volume adequate to ensure that the oxygen con

vacuum packaging appliances
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

The text of this International Standard is based on the following documents:
Draft Report on voting
61/6176/CDV 61/6295/RVC
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.

– 4 – IEC 60335-2-119:2021 © IEC 2021
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 in the IEC 60335 series, published 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 commercial vacuum
packaging appliances.
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 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 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 2-119: Particular requirements for commercial
vacuum packaging appliances
1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of commercial electric packaging appliances using
vacuum conditions for food preservation, their rated voltage being not more than 250 V for
single-phase appliances and 480 V for other appliances.
These appliances are not intended for household and similar purposes. They are used for
commercial preservation of food in areas not open to the public, for example in kitchens of
restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries.
Examples of appliances that are within the scope of this standard are:
– chamber vacuum packaging appliances;
– vacuum packaging appliances.
These appliances may be provided with a film-sealing function.
This standard also deals with the hygiene aspects of appliances.
As far as is practicable, this standard deals with the common hazards presented by appliances
that are encountered by users. However, in general, it does not consider young children playing
with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or onboard ships or aircraft, additional
requirements may be necessary;
– in many countries, additional requirements for appliances incorporating pressure vessels
are specified;
– in many countries, additional requirements are specified by the national health authorities,
the national authorities responsible for the protection of labour, the national water supply
authorities and similar authorities.
This standard does not apply to:
– appliances which operate with injection in the vacuum chamber of inert gas with an oxygen
content exceeding 21 %;
– 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);
– vacuum packaging appliances for household and similar use (IEC 60335-2-45);
– battery-operated appliances.

Annexes
The annexes of Part 1 are applicable except as follows.

Annex AA
(informative)
Method for calculating the gas concentration
AA.1 Calculation of gas concentration
The following information shall be considered by the manufacturer. If the manufacturer does
not clearly specify and limit the size of the working space and the gas cylinder, the following
information shall be given in the instructions.
AA.2 Calculations for safe operation with protective gases (modified
atmosphere packaging)
AA.2.1 Guidance for the evaluation of ventilation requirements
The ventilation requirements depend on numerous factors such as location, type of gas and
possible leaks. Ventilation can be natural or forced ventilation. The normal index to be
considered is the number of air exchanges per hour.
Typically, the required number of air exchanges can be calculated based on an estimated gas
outlet or leakage rate of a machine in operation. A homogeneous gas distribution is assumed,
and the following formula is applied:
-nt×
Le× 1-
( )
C =
t
Vn×
r
where
C is the gas concentration at time t;
t
L is the gas flow [m /h];
V is the volume of the room [m ];
r
n are the air exchanges per hour;
t is the time of gas flow in hours.
For long periods of time (t with a tendency towards infinity), the following applies:
L
C∞=
Vn ×
r
Since this calculation refers to continuous gas discharge, the goal shall be to keep the oxygen
concentration between 20 % and 22 % by sufficient ventilation (air exchanges).
Natural air ventilation rates can be evaluated as follows:
• In above-ground locations without special ventilation openings, natural ventilation generally
achieves one air exchange per hour. However, this does not apply to buildings in which the
windows are gas tight.
• If special ventilation openings are available, up to two air changes per hour can be assumed.
• For underground rooms with small windows, an average natural air exchange rate of 0,4 per
hour can be assumed.
– 18 – IEC 60335-2-119:2021 © IEC 2021
• For more than 2 air exchanges per hour a forced ventilation system is required.
Special building regulations may recommend or require a specific number of air exchanges per
hour for different conditions, i.e. 5, 10, 20.
In case of doubt on required air exchanges, contact an appropriately licensed ventilation
technician or refer to building regulations concerning the specific installation.
AA.2.2 Calculation for the use of gas cylinders in rooms
This requirement deals with the worst-case scenario, where the entire contents of a gas cylinder
or storage container leak into the room immediately as a result of a catastrophic failure, such
as a burst hose, a leaking pipe connection or a permanently open gas valve. The trigger for
such an event could be the failure of a regulator.
In the event of such a catastrophic scenario, mastering the situation is initially more important
than trying to restore an atmosphere suitable as a working environment. For this reason, an
oxygen concentration of 25 % is acceptable in the short term.
The calculation can also be performed for oxygen replacing gases. In this case, it is essential
that the oxygen concentration shall not fall be
