SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR
MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 2-061: Particular requirements for laboratory atomic
spectrometers with thermal atomization and ionization

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 redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

pressure levels, for example as a result of FLASH-BACK in a burner gas mixing chamber, shall
not produce a sound power level in excess of 140 dB(A).
Add, after Note 2, the following new note:
NOTE 101 Exposure to noise has been categorized in many countries by three action levels of “daily personal
noise exposure” at 85 dBA, 90 dBA, and 140 dBA. “Daily personal noise exposure” is defined as the total exposure
over the whole working day, taking into account the varying noise levels in the working environment and how long a
person is exposed to them, without taking account of whether ear protectors are worn.

The peak action level of 140 dBA relates to cartridge operated tools, shooting guns, and similar loud explosive
noises. This action level is most important where workers are subject to a small number of loud impulses during an
otherwise quiet day.
Employers in many countries are required to reduce the risk of damage to the hearing of employees from exposure
to noise to the lowest level reasonably practicable. For example some countries require manufacturers to provide
suitable and efficient ear protectors on request, to employees whose daily personal exposure is between 80 dBA
and 90 dBA. For exposures above 90 dBA, exposure is required to be reduced to the lowest level reasonably
practicable without taking account of the use of ear protectors. At the same time, suitable ear protectors are to be
provided by the employer.
13 Protection against liberated gases and substances, explosion and implosion
This clause of Part 1 is applicable except as follows:
13.1 Poisonous and injurious gases and substances
Addition:
Add, after the first second paragraph, the following new notes:
NOTE 101 Discharge of gases into a fume extraction system is not considered to be liberation (see 5.4.3 bb)).
NOTE 102 Absence of fluid from the type of GAS LOCK shown in Figure 101 is a typical SINGLE FAULT CONDITION.

Figure 101 – Example of a GAS LOCK
13.2.1 Components
Replacement:
Replace the first paragraph by with the following new text:
If an explosion could can occur either by FLASH-BACK of gases in a burner and mixing
chamber, or if components, if overheated or overcharged, are not provided with a pressure
relief device, protection for the OPERATOR and other persons shall be incorporated in the
equipment (see also 7.7).
Replace the conformity statement by with the following new text:

– 14 – IEC 61010-2-061:2018 RLV © IEC 2018
Conformity is checked by inspection and, for burners, by test a) or b) as appropriate:
a) for burners designed to prevent FLASH-BACK, the flame is ignited and the flow of gas
mixture, maintained at a constant fuel-oxidant ratio, is gradually reduced to zero. The
flame shall extinguish without FLASH-BACK;
b) for other burners, the flame is ignited and the gas mixture adjusted so as to generate the
FLASH-BACK.
maximum energy flame. Ignition is then initiated inside the burner to simulate
No parts shall be expelled outside the equipment.
Addition:
Add the following new subclauses:
13.101 Flame ignition system
For equipment which has an automatically controlled ignition system, the ignition procedure
when started shall either cause the flame to ignite in a time less than that required for 0,8 l of
fuel-gas to be delivered, or the ignition procedure shall be ended automatically and the
equipment returned to stand-by condition. For equipment which does not have an
automatically controlled ignition system, it shall not be possible to open the valves which
control the flows of fuel-gas and oxidant-gas (except compressed air) for purposes of igniting
the flame, unless a manually operated device as described below is provided.
An acceptable manually operated device is one which satisfies the following criteria:
a) it shall override the flame-failure gas shut-off device for not longer than the time for 0,8 l
of fuel-gas to be delivered;
NOTE For fuel-gas, the litre (l) will be understood as that which is measured at 0 °C and 0,1 MPa (1 bar).
b) it shall allow the gases to flow to permit the necessary adjustment of the flow rates before
the ignition system is operated;
c) if ignition is not achieved, the gas flow valves shall close immediately as soon as the
device is released.
Conformity is checked by fitting a gas flow-rate meter in the fuel-gas pipe and measuring both
the rate of gas escaping during the ignition procedure in NORMAL USE, and the time from
opening the fuel-gas inlet valve to closing it after ignition failures. The gas volume is
calculated from these measurements.
13.102 Non-interchangeability of gas connectors
Connectors available to the OPERATOR for fuel-gas shall not be interchangeable with
connectors for oxidant-gas.
Conformity is checked by inspection.
13.103 Interchangeable burners
In equipment with interchangeable burners (for example to permit the use of either air or
nitrous oxide as the oxidant gas) and where a HAZARD could arise if the incorrect gas is fed to
a burner, it shall only be possible to operate with a gas appropriate to the burner fitted.
Conformity is checked by fitting, in turn, each available burner specified by the manufacturer,
and confirming that only the gases specified for a burner can flow to the burner.
14 Components and subassemblies
This clause of Part 1 is applicable.

15 Protection by interlocks
This clause of Part 1 is applicable except as follows:
15.1 General
Addition:
Add, after the first paragraph, the following new text:
As an alternative method, for interlock systems containing electric/electronic or programmable
components (E/E/P components) the reliability and design requirements can be determined by
applying for example IEC 62061 (SIL) or ISO 13849 (all parts) (PL) or other solutions
providing equivalent functional safety.
16 HAZARDS resulting from application
This clause of Part 1 is applicable.
17 RISK assessment
This clause of Part 1 is applicable.

Routine tests
Addition:
Add the following new subclause:
F.101 Gas leakage test
A test is carried out to measure leakage of gas from the internal system leading to the burner.
The worst-case gas intended to be used in that internal system is applied at 1,2 times the
maximum inlet pressure for NORMAL USE. An alternative gas (for example helium) can be used
provided that the results, when converted, are equivalent to the results had the worst-case
gas been used. Leakage shall not exceed 5 ml/min.

aa) a reminder to the RESPONSIBLE BODY of the responsibility for the correct collection and
disposal of waste materials, including the necessity for:
1) a suitably sized waste container of appropriately resistant material for the collection
of organic solvent waste;
NOTE The proper disposal of waste materials is well documented by national authorities and it is these
procedures that supersede the requirements of this document in regard of waste disposal. This Part 2 only
brings to the attention of the OPERATOR that potentially hazardous waste materials are present and
national (local) regulations for the proper disposal can apply.
2) provision for the removal into an appropriate exhaust system of any gases or
vapours which may be produced in hazardous concentrations;
bb) a list of fluids known by the manufacturer to be potentially unsafe if used with the
equipment.
Add, after the list of items, the following new paragraph:
Documentation shall also indicate that this list cannot be taken to be exhaustive and that, in
case of uncertainty about a specific fluid, that fluid shall not be used until confirmation by the
manufacturer that it will not present a HAZARD.
Add the following new subclause:
5.4.4.101 Cleaning and decontamination
Documentation shall indicate:
a) that the RESPONSIBLE BODY has the responsibility for carrying out appropriate
decontamination if hazardous material is spilt on or inside the equipment;
b) the manufacturer's recommendations for cleaning and, where necessary, decontamination,
together with the recognized generic names of recommended materials for cleaning and
decontamination.
The following wording shall appear in the documentation:
“Before using any cleaning or decontamination methods except those specified by the
manufacturer, the RESPONSIBLE BODY should check with the manufacturer that the proposed
method will not damage the equipment.”

If a manufacturer claims that an item can be decontaminated by steam sterilization, it shall be
capable of withstanding steam sterilization under at least one of the time-temperature
conditions given in Table 101. Cleaning and decontamination shall be necessary as a
safeguard when spectrometers and their accessories are maintained, repaired, or transferred.
Manufacturers shall provide a format for the RESPONSIBLE BODY to certify that such a treatment
has been carried out.
NOTE Information on decontaminants, their use, dilution and potential application is contained in the Laboratory
Biosafety Manual, published by the World Health Organization and the Biosafety in Microbiological and Biomedical
Laboratories, published by Centers for Disease Control and Prevention and National Institutes of Health,
Washington. There are also national guidelines that cover these areas.

11 Protection against HAZARDS from fluids and solid foreign objects
This clause of Part 1 is applicable except as follows:
11.1 General
Replacement:
Replace the first paragraph with the following new paragraph:
Equipment shall be designed to give protection to the OPERATOR, other persons in the vicinity,
and the surrounding area against HAZARDS from direct contact with fluids encountered in

11.101 Sampling probes
Sample fluid remaining on the outside of a sampling probe shall not cause a HAZARD to the
OPERATOR or other persons in the vicinity.
Conformity is checked by inspection and, if necessary, by a test using a suitable fluid, for
example a solution of fluorescein in water.

11.102 Gases
Components within the fuel-gas and oxidant paths shall be resistant to the gases specified by
the manufacturer, and to any associated solvent vapours. In the case of acetylene, a solvent,
for example acetone, will be present in the cylinder which contains the acetylene. Any special
national regulations for the safe use of gases and pressurized gas cylinders shall be
observed.
Conformity is checked by inspection and by examination of the specification of the materials
used.
11.103 Solvents
Parts in contact with solvents, including any which will be contacted by diffusion of vapour in
the stand-by condition, shall be resistant to the solvents specified by the manufacturer.
Conformity is checked by inspection and examination of the specification of the materials

c) silver and silver alloys, except for brazing. Silver filler used for brazing shall have a silver
content of less than 43 %, and a copper content of less than 21 %. The width of a solder
gap, where the silver filler might come into contact with acetylene, shall be less than 0,3
mm;
d) any other material which may form an explosive acetylide.
Conformity is checked by inspection of the materials used and their specification according to
the manufacturer.
12 Protection against radiation, including laser sources, and against sonic and
ultrasonic pressure
This clause of Part 1 is applicable except as follows:
12.5.1 Sound level
Addition:
Add, before Note 1, the following new paragraph:
Equipment which may generate occasional and unavoidable short-duration high sound
pressure levels, for example as a result of FLASH-BACK in a burner gas mixing chamber, shall
not produce a sound power level in excess of 140 dB(A).
Add, after Note 2, the following new note:
NOTE 101 Exposure to noise has been categorized in many countries by three action levels of “daily personal
noise exposure” at 85 dBA, 90 dBA, and 140 dBA. “Daily personal noise exposure” is defined as the total exposure
over the whole working day, taking into account the varying noise levels in the working environment and how long a
person is exposed to them, without taking account of whether ear protectors are worn.

– 12 – IEC 61010-2-061:2018 © IEC 2018
The peak action level of 140 dBA relates to cartridge operated tools, shooting guns, and similar loud explosive
noises. This action level is most important where workers are subject to a small number of loud impulses during an
otherwise quiet day.
Employers in many countries are required to reduce the risk of damage to the hearing of employees from exposure
to noise to the lowest level reasonably practicable. For example some countries require manufacturers to provide
suitable and efficient ear protectors on request, to employees whose daily personal exposure is between 80 dBA
and 90 dBA. For exposures above 90 dBA, exposure is required to be reduced to the lowest level reasonably
practicable without taking account of the use of ear protectors. At the same time, suitable ear protectors are to be
provided by the employer.
13 Protection against liberated gases and substances, explosion and implosion
This clause of Part 1 is applicable except as follows:
13.1 Poisonous and injurious gases and substances
Addition:
Add, after the second paragraph, the following new notes:
NOTE 101 Discharge of gases into a fume extraction system is not considered to be liberation (see 5.4.3 bb)).
NOTE 102 Absence of fluid from the type of GAS LOCK shown in Figure 101 is a typical SINGLE FAULT CONDITION.

Figure 101 – Example of a GAS LOCK
13.2.1 Components
Replacement:
Replace the first paragraph with the following new text:
If an explosion can occur either by FLASH-BACK of gases in a burner and mixing chamber, or if
components, if overheated or overcharged, are not provided with a pressure relief device,
protection for the OPERATOR and other persons shall be incorporated in the equipment (see
also 7.7).
Replace the conformity statement with the following new text:

Conformity is checked by inspection and, for burners, by test a) or b) as appropriate:
a) for burners designed to prevent FLASH-BACK, the flame is ignited and the flow of gas
mixture, maintained at a constant fuel-oxidant ratio, is gradually reduced to zero. The
flame shall extinguish without FLASH-BACK;
b) for other burners, the flame is ignited and the gas mixture adjusted so as to generate the
FLASH-BACK.
maximum energy flame. Ignition is then initiated inside the burner to simulate
No parts shall be expelled outside the equipment.
Addition:
Add the following new subclauses:
13.101 Flame ignition system
For equipment which has an automatically controlled ignition system, the ignition procedure
when started shall either cause the flame to ignite in a time less than that required for 0,8 l of
fuel-gas to be delivered, or the ignition procedure shall be ended automatically and the
equipment returned to stand-by condition. For equipment which does not have an
automatically controlled ignition system, it shall not be possible to open the valves which
control the flows of fuel-gas and oxidant-gas (except compressed air) for purposes of igniting
the flame, unless a manually operated device as described below is provided.
An acceptable manually operated device is one which satisfies the following criteria:
a) it shall override the flame-failure gas shut-off device for not longer than the time for 0,8 l
of fuel-gas to be delivered;
NOTE For fuel-gas, the litre (l) will be understood as that which is measured at 0 °C and 0,1 MPa (1 bar).
b) it shall allow the gases to flow to permit the necessary adjustment of the flow rates before
the ignition system is operated;
c) if ignition is not achieved, the gas flow valves shall close as soon as the device
is released.
Conformity is checked by fitting a gas flow-rate meter in the fuel-gas pipe and measuring both
the rate of gas escaping during the ignition procedure in NORMAL USE, and the time from
opening the fuel-gas inlet valve to closing it after ignition failures. The gas volume is
calculated from these measurements.
13.102 Non-interchangeability of gas connectors
Connectors available to the OPERATOR for fuel-gas shall not be interchangeable with
connectors for oxidant-gas.
Conformity is checked by inspection.
13.103 Interchangeable burners
In equipment with interchangeable burners (for example to permit the use of either air or
nitrous oxide as the oxidant gas) and where a HAZARD could arise if the incorrect gas is fed to
a burner, it shall only be possible to operate with a gas appropriate to the burner fitted.
Conformity is checked by fitting, in turn, each available burner specified by the manufacturer,
and confirming that only the gases specified for a burner can flow to the burner.
14 Components and subassemblies
This clause of Part 1 is applicable.

15.1 General
Addition:
Add, after the first paragraph, the following new text:
As an alternative method, for interlock systems containing electric/electronic or programmable
components (E/E/P components) the reliability and design requirements can be determined by
applying for example IEC 62061 (SIL) or ISO 13849 (all parts) (PL) or other solutions
providing equivalent functional safety.
