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.

INTRODUCTION
IEC 60754 consists of the following parts, under the general title: Test on gases evolved
during combustion of materials from cables:
– Part 1: Determination of the halogen acid gas content
– Part 2: Determination of acidity (by pH measurement) and conductivity
– Part 3: Measurement of low level of halogen content by ion chromatography
NOTE Guidance on the corrosivity of fire effluent is given in IEC 60695-5-1.
IEC 60754-1 and IEC 60754-2 were developed due to concerns expressed by cable users
over the amount of acid gas which is evolved when some cable insulating, sheathing and
other materials are burned, as this acid and such corrosive effluents can cause extensive
damage to electrical and electronic equipment not involved in the fire itself.
IEC 60754-1 provides a method for determining the amount of acid gases evolved by burning
cable components so that limits can be agreed for cable specifications.
IEC 60754-2 provides a method for determining the acidity (by pH measurement) and
conductivity of an aqueous solution of gases evolved during the combustion of materials so
that limits can be agreed for cable specifications
IEC 60754-1 is not able to determine hydrofluoric acid and, for reasons of precision, this
method is not recommended for reporting values of halogen acid evolved less than 5 mg/g of
the sample taken.
This document provides a method for measurement of low level of halogen content of the
gases evolved by burning cable and has a high accuracy in the low range of concentration.
The ion chromatic system has an inherently high accuracy. However, the overall accuracy of
the test method is limited by other factors (see Annex A for further information).
This part of IEC 60754 is linked with IEC 60754-2, using the same test procedure for
obtaining the absorption solution.

TEST ON GASES EVOLVED DURING
COMBUSTION OF MATERIALS FROM CABLES –
Part 3: Measurement of low level of halogen
content by ion chromatography
1 Scope
This part of IEC 60754 specifies the apparatus and procedure for the measurement of the
amount of halogens evolved during the combustion of materials taken from electric or optical
fibre cable constructions.
The method specified in this document is intended for the measurement of the content of
chlorine (Cl), bromine (Br), fluorine (F) and iodine (I), by using the analytical technique of ion
chromatography for analysing an aqueous solution resulting from the gases evolved during
the combustion.
The heating (combustion) procedure in this part of IEC 60754 is the same as in IEC 60754-2.
The method is intended for materials with an individual halogen content not exceeding
10 mg/g.
The method specified in this document is intended for the testing of individual components
used in a cable construction. The use of this method will enable the verification of
requirements which are stated in the appropriate cable specification for individual components
of a cable construction.
NOTE 1 The relevant cable standard indicates which components of the cable are tested.
NOTE 2 This test method is sometimes used to test materials to be used in cable manufacture.
For reasons of precision, this method is not recommended for detecting values of halogens
less than 0,1 mg/g of the sample taken.

4 Test method principle
The material under test shall be heated in a stream of dry air. The evolved gases shall be
trapped by bubbling through wash bottles filled with distilled or demineralized water.
Each individual halogen content of the resulting solution shall then be determined by using ion
chromatography (IC).
The ion chromatography analysis can be done off line and does not have to be in line.
5 Test apparatus
5.1 General
The apparatus is shown in Figure 1 to Figure 5.
The assembly of the components which constitute the test apparatus shall be leak-tight. The
connecting distances between the quartz glass tube and the first bottle and between
subsequent bottles shall be as short as possible. Quartz glass or polypropylene tubing shall
be used for these connections, unless it is not required to measure and report fluorine, in
which case glass or silicone rubber may be used.
At the exit side of the quartz glass tube, as close to the end as possible, it is permitted to
place a plug of silica wool to aid collection of condensates.
A third empty bottle, of the same size as the gas washing bottles, placed before the gas
washing bottles may be used to improve safety, i.e. to prevent suck-back of water into the
quartz glass tube.
5.2 Tube furnace
The length of the heating zone of the furnace shall be within the range 480 mm to 620 mm
and its inside diameter shall be within the range 38 mm to 62 mm. It shall be equipped with an
adjustable electrical heating system.

SIST EN IEC 60754-3:2019
IEC 60754-3:2018 © IEC 2018 – 9 –
5.3 Quartz glass tube
For the test, a quartz glass tube shall be introduced into the tube furnace. The tube shall be
approximately concentric to the furnace. It shall be resistant to the action of corrosive gases.
The inside diameter of the tube shall be within the range 30 mm to 46 mm. The tube shall
protrude on the entrance side of the furnace by a length of between 60 mm to 200 mm, and
on the exit side by between 60 mm to 100 mm. The initial clearance shall allow for thermal
expansion. For the purposes of measurement of the protrusion distances, the tube shall be
regarded as that part of essentially constant diameter.
The outer diameter of the tube should be chosen with due regard to the inside diameter of the
tube furnace.
Prior to each test, the tube shall be cleaned throughout its length by being calcined at
approximately 950 °C.
5.4 Combustion boat
The combustion boat shall be made of porcelain, fused quartz or soapstone. In case the
method is used to report fluorine, the combustion boat shall be made of quartz glass. The
combustion boat shall have the following dimensions:
– external length: within the range 45 mm to 100 mm;
– external width: within the range 12 mm to 30 mm;
– internal depth: within the range 5 mm to 10 mm.
The dimensions of the boat should be chosen with due regard to the inside diameter of the
quartz tube.
The preferred method for insertion of the combustion boat into the quartz glass tube is shown
in Figure 1.
Prior to each test, the combustion boat shall be washed and calcined in a muffle furnace at
approximately 950 °C for 4 h, after which it shall be introduced into a desiccator and cooled to
ambient temperature. The combustion boat shall then be weighed with a precision of
shall be
≤ 0,1 mg until two identical consecutive weights are obtained. This weight m
1
recorded.
5.5 Bubbling devices for gases
At the exit of the quartz glass tube, the evolved gases shall be trapped by bubbling through
two wash bottles (see Figure 2), each containing approximately 450 ml of distilled or
demineralized water of a purity at least Grade 3 in accordance with ISO 3696.
The wash bottles shall be made of quartz glass, unless it is not required to measure and
report fluorine, in which case wash bottles made of glass may be used.
The pH value of the water shall be between 5,5 and 7,5, and the conductivity less than
0,5 µS/mm.
A magnetic stirrer shall be introduced in the first wash bottle, to get a good swirling motion
and an effective absorption of the combustion gases. The tubes into the wash bottles shall
have a maximum internal diameter at their tip of 5 mm, in order to aid absorption.
The height of the liquid above the end of the tube shall be (110 ± 10) mm in each bottle.
NOTE Use of a wash bottle of internal diameter approximately 75 mm will enable this requirement to be met.

5.6 Air supply system
The gas used for combustion shall be air.
2
The flow rate of air, ρ, shall be 20 m/h x (π/4) x D with a tolerance of ± 10 %, where D is the
internal diameter of the quartz tube.
EXAMPLES
2
If D = 30 mm, 20 m/h × (π/4) × D = 14,1 l/h, and the flow rate can be in the range 12,7 l/h to 15,5 l/h.
2
If D = 46 mm, 20 m/h × (π/4) × D = 33,2 l/h, and the flow rate can be in the range 29,9 l/h to 36,5 l/h.
NOTE The flow rate of air, ρ, is related to the velocity, v, according to the formula
2
π D
[1]
ρ= v×
4
where
D is the internal diameter of the tube (mm);
ρ is the flow rate of air (ml/h);
2
v is the speed of air (ml/mm /h).
2
If v = 20 m/h, this becomes, ρ = 15,7 m/h × D
The air supply shall be adjusted and controlled by a needle valve, and the flow rate monitored
by a flowmeter of the appropriate range.
The air supplied shall be selected from one of the following methods:
Method 1
This method uses synthetic air or compressed air from a bottle. The air shall be introduced on
the inlet side of the quartz glass tube (see Figure 3).
Method 2
This method uses a laboratory compressed air supply. The air shall be filtered and dried and
shall be introduced on the inlet side of the quartz glass tube (see Figure 4).
Method 3
This method uses the ambient air of the laboratory. The air shall be filtered and dried. In this
case, the mixture of air and combustion gas shall be sucked by a pump (see Figure 5).
5.7 Analytical balance
The balance shall have a precision of ± 0,1 mg or better.

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.

INTRODUCTION
IEC 60754 consists of the following parts, under the general title: Test on gases evolved
during combustion of materials from cables:
– Part 1: Determination of the halogen acid gas content
– Part 2: Determination of acidity (by pH measurement) and conductivity
– Part 3: Measurement of low level of halogen content by ion chromatography
NOTE Guidance on the corrosivity of fire effluent is given in IEC 60695-5-1.
IEC 60754-1 and IEC 60754-2 were developed due to concerns expressed by cable users
over the amount of acid gas which is evolved when some cable insulating, sheathing and
other materials are burned, as this acid and such corrosive effluents can cause extensive
damage to electrical and electronic equipment not involved in the fire itself.
IEC 60754-1 provides a method for determining the amount of acid gases evolved by burning
cable components so that limits can be agreed for cable specifications.
IEC 60754-2 provides a method for determining the acidity (by pH measurement) and
conductivity of an aqueous solution of gases evolved during the combustion of materials so
that limits can be agreed for cable specifications
IEC 60754-1 is not able to determine hydrofluoric acid and, for reasons of precision, this
method is not recommended for reporting values of halogen acid evolved less than 5 mg/g of
the sample taken.
This document provides a method for measurement of low level of halogen content of the
gases evolved by burning cable and has a high accuracy in the low range of concentration.
The ion chromatic system has an inherently high accuracy. However, the overall accuracy of
the test method is limited by other factors (see Annex A for further information).
This part of IEC 60754 is linked with IEC 60754-2, using the same test procedure for
obtaining the absorption solution.

TEST ON GASES EVOLVED DURING
COMBUSTION OF MATERIALS FROM CABLES –
Part 3: Measurement of low level of halogen
content by ion chromatography
1 Scope
This part of IEC 60754 specifies the apparatus and procedure for the measurement of the
amount of halogens evolved during the combustion of materials taken from electric or optical
fibre cable constructions.
The method specified in this document is intended for the measurement of the content of
chlorine (Cl), bromine (Br), fluorine (F) and iodine (I), by using the analytical technique of ion
chromatography for analysing an aqueous solution resulting from the gases evolved during
the combustion.
The heating (combustion) procedure in this part of IEC 60754 is the same as in IEC 60754-2.
The method is intended for materials with an individual halogen content not exceeding
10 mg/g.
The method specified in this document is intended for the testing of individual components
used in a cable construction. The use of this method will enable the verification of
requirements which are stated in the appropriate cable specification for individual components
of a cable construction.
NOTE 1 The relevant cable standard indicates which components of the cable are tested.
NOTE 2 This test method is sometimes used to test materials to be used in cable manufacture.
For reasons of precision, this method is not recommended for detecting values of halogens
less than 0,1 mg/g of the sample taken.

• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
halogen
element of periodic table group 17, specifically fluorine, chlorine, bromine, iodine
3.2
individual halogen content
amount of a halogen in a test specimen that can be converted to water soluble halide ion in
the gaseous combustion effluent from the test specimen
Note 1 to entry: Halide ions are fluoride, chloride, bromide or iodide.
Note 2 to entry: The halogen in the test specimen may be in the form of organic or inorganic compounds.
Note 3 to entry: The individual halogen content is expressed as milligrams of halogen per gram of test specimen.
Note 4 to entry: Halide ions in any solid combustion residue that remains in the combustion boat are not
measured by this test method.
4 Test method principle
The material under test shall be heated in a stream of dry air. The evolved gases shall be
trapped by bubbling through wash bottles filled with distilled or demineralized water.
Each individual halogen content of the resulting solution shall then be determined by using ion
chromatography (IC).
The ion chromatography analysis can be done off line and does not have to be in line.
5 Test apparatus
5.1 General
The apparatus is shown in Figure 1 to Figure 5.
The assembly of the components which constitute the test apparatus shall be leak-tight. The
connecting distances between the quartz glass tube and the first bottle and between
subsequent bottles shall be as short as possible. Quartz glass or polypropylene tubing shall
be used for these connections, unless it is not required to measure and report fluorine, in
which case glass or silicone rubber may be used.
At the exit side of the quartz glass tube, as close to the end as possible, it is permitted to
place a plug of silica wool to aid collection of condensates.
A third empty bottle, of the same size as the gas washing bottles, placed before the gas
washing bottles may be used to improve safety, i.e. to prevent suck-back of water into the
quartz glass tube.
5.2 Tube furnace
The length of the heating zone of the furnace shall be within the range 480 mm to 620 mm
and its inside diameter shall be within the range 38 mm to 62 mm. It shall be equipped with an
adjustable electrical heating system.

oSIST prEN IEC 60754-3:2019
IEC 60754-3:2018 © IEC 2018 – 9 –
5.3 Quartz glass tube
For the test, a quartz glass tube shall be introduced into the tube furnace. The tube shall be
approximately concentric to the furnace. It shall be resistant to the action of corrosive gases.
The inside diameter of the tube shall be within the range 30 mm to 46 mm. The tube shall
protrude on the entrance side of the furnace by a length of between 60 mm to 200 mm, and
on the exit side by between 60 mm to 100 mm. The initial clearance shall allow for thermal
expansion. For the purposes of measurement of the protrusion distances, the tube shall be
regarded as that part of essentially constant diameter.
The outer diameter of the tube should be chosen with due regard to the inside diameter of the
tube furnace.
Prior to each test, the tube shall be cleaned throughout its length by being calcined at
approximately 950 °C.
5.4 Combustion boat
The combustion boat shall be made of porcelain, fused quartz or soapstone. In case the
method is used to report fluorine, the combustion boat shall be made of quartz glass. The
combustion boat shall have the following dimensions:
– external length: within the range 45 mm to 100 mm;
– external width: within the range 12 mm to 30 mm;
– internal depth: within the range 5 mm to 10 mm.
The dimensions of the boat should be chosen with due regard to the inside diameter of the
quartz tube.
The preferred method for insertion of the combustion boat into the quartz glass tube is shown
in Figure 1.
Prior to each test, the combustion boat shall be washed and calcined in a muffle furnace at
approximately 950 °C for 4 h, after which it shall be introduced into a desiccator and cooled to
ambient temperature. The combustion boat shall then be weighed with a precision of
shall be
≤ 0,1 mg until two identical consecutive weights are obtained. This weight m
1
recorded.
5.5 Bubbling devices for gases
At the exit of the quartz glass tube, the evolved gases shall be trapped by bubbling through
two wash bottles (see Figure 2), each containing approximately 450 ml of distilled or
demineralized water of a purity at least Grade 3 in accordance with ISO 3696.
The wash bottles shall be made of quartz glass, unless it is not required to measure and
report fluorine, in which case wash bottles made of glass may be used.
The pH value of the water shall be between 5,5 and 7,5, and the conductivity less than
0,5 µS/mm.
A magnetic stirrer shall be introduced in the first wash bottle, to get a good swirling motion
and an effective absorption of the combustion gases. The tubes into the wash bottles shall
have a maximum internal diameter at their tip of 5 mm, in order to aid absorption.
The height of the liquid above the end of the tube shall be (110 ± 10) mm in each bottle.
NOTE Use of a wash bottle of internal diameter approximately 75 mm will enable this requirement to be met.

5.6 Air supply system
The gas used for combustion shall be air.
2
The flow rate of air, ρ, shall be 20 m/h x (π/4) x D with a tolerance of ± 10 %, where D is the
internal diameter of the quartz tube.
EXAMPLES
2
If D = 30 mm, 20 m/h × (π/4) × D = 14,1 l/h, and the flow rate can be in the range 12,7 l/h to 15,5 l/h.
2
If D = 46 mm, 20 m/h × (π/4) × D = 33,2 l/h, and the flow rate can be in the range 29,9 l/h to 36,5 l/h.
NOTE The flow rate of air, ρ, is related to the velocity, v, according to the formula
2
π D
[1]
ρ= v×
4
where
D is the internal diameter of the tube (mm);
ρ is the flow rate of air (ml/h);
2
v is the speed of air (ml/mm /h).
2
If v = 20 m/h, this becomes, ρ = 15,7 m/h × D
The air supply shall be adjusted and controlled by a needle valve, and the flow rate monitored
by a flowmeter of the appropriate range.
The air supplied shall be selected from one of the following methods:
Method 1
This method uses synthetic air or compressed air from a bottle. The air shall be introduced on
the inlet side of the quartz glass tube (see Figure 3).
Method 2
This method uses a laboratory compressed air supply. The air shall be filtered and dried and
shall be introduced on the inlet side of the quartz glass tube (see Figure 4).
Method 3
This method uses the ambient air of the laboratory. The air shall be filtered and dried. In this
case, the mixture of air and combustion gas shall be sucked by a pump (see Figure 5).
5.7 Analytical balance
The balance shall have a precision of ± 0,1 mg or better.
5.8 Laboratory glassware
The following laboratory glassware shall be available:
– one mark volumetric flask in accordance with ISO 1042 class B with 1 000 ml capacity.
The volumetric flask shall be made of quartz glass or polypropylene, unless it is not required
to measure and report fluorine, in which case a volumetric flask made of glass may be used.
