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.
International Standard IEC 61010-2-061 has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.
It has the status of a group safety publication in accordance with IEC Guide 104.
This third edition cancels and replaces the second edition published in 2003. It constitutes a
technical revision and includes the following change from the second edition:
• exclusion of equipment, whose size and weight make unintentional movement unlikely,
from the drop test in Clause 8.
• notes have been re-phrased according to ISO/IEC Directives.

This Part 2-061 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
convert that publication into the IEC standard: Safety requirements for laboratory atomic
spectrometers with thermal atomization and ionization.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this part states “addition”, “modification” or “replacement”, or
“deletion”, the relevant requirement, test specification or note in Part 1 should be adapted
accordingly.
In this standard:
1) the following print types are used:
– requirements: in roman type;
– NOTES: in small roman type;
– conformity and test: in italic type;
– terms used throughout this standard which have been defined in clause 3: SMALL ROMAN
CAPITALS;
2) subclauses, figures, tables and notes which are additional to those in Part 1 are numbered
starting from 101. The additional annexes are lettered starting from AA.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

The voltage of the power supply to the equipment from the MAINS supply shall first be reduced
to just less than 90 % of the RATED voltage, and shall then be switched off.
5 Marking and documentation
This clause of Part 1 is applicable except as follows:
Addition:
Add the following subclause:
5.1.5.101 Gas and liquid connections
The following shall be unambiguously marked adjacent to the connector on the equipment
(see 5.2):
a) the identity of the gas or liquid;
b) the maximum permitted pressure,
c) flow direction of the gas and liquid, if applicable.
NOTE Such markings may be specific (for example acetylene, propane, water) or generic (for example fuel gas,
oxidant gas, coolant, waste liquid).
Where no internationally recognized symbol (such as a chemical formula) exists, the equip-
ment shall be marked with symbol 14 of Table 1 together with an unambiguous text in English.
The documentation accompanying the equipment shall provide an adequate translation of this
text (where it is required) in the language of the country in which it is to be installed, to assure

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 supersede the requirements of this standard in regard of waste disposal. This part 2 should only
bring 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.

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.

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, a new paragraph as follows:
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 a note as follows:
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:
– 12 – IEC 61010-2-061:2015 © IEC 2015
13.1 Poisonous and injurious gases and substances
Addition:
Add, after the first 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.

13.2.1 Components
Replacement:
Replace the first paragraph by the following:
If an explosion could 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 the following:
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
maximum energy flame. Ignition is then initiated inside the burner to simulate FLASH-BACK.
No parts shall be expelled outside the equipment.
Addition:
Add the following 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 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
HAZARD could arise if the incorrect gas is fed to
nitrous oxide as the oxidant gas) and where a
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.

Routine tests
Addition:
Add the following 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.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. À cet effet, l’IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent
également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internat
