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 IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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.
This second edition cancels and replaces the first edition published in 1995, of which it
constitutes a technical revision.
It has the status of a group safety publication in accordance with IEC Guide 104.
The text of this standard is based on the following documents:
FDIS Report on voting
66/326/FDIS 66/331/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Part 2-061 is intended to be used in conjunction with IEC 61010-1. It was established
on the basis of the second edition (2001). Consideration may be given to future editions of, or
amendments to, IEC 61010-1.
– 4 – 61010-2-061  IEC:2003(E)
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 committee has decided that the contents of this publication will remain unchanged until 2007.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

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
1 Scope and object
This clause of Part 1 is applicable except as follows:
1.1 Scope
1.1.1 Equipment included in scope
Replacement:
This part of IEC 61010 applies to electrically powered laboratory atomic spectrometers with
thermal atomization.
NOTE 1 Examples include atomic absorption spectrometers, emission flame photometers, atomic fluorescence
spectrophotometers, inductively coupled plasma spectrometers, microwave coupled plasma spectrometers and
mass spectrometers, all with thermal atomization and ionization (including tubing and connectors which are
provided by the manufacturer for connection to external supplies).
NOTE 2 If all or part of the equipment falls within the scope of one or more other part 2 standards of IEC 61010
as well as within the scope of this standard, it will also need to meet the requirements of those other part 2
standards.
1.1.2 Equipment excluded from scope
Addition:
Add as the first paragraph:
This standard does not apply to thermal atomization detectors (flame ionization detectors)
used in gas chromatography.
2 Normative references
This clause of Part 1 is applicable.
3 Definitions
This clause of Part 1 is applicable except as follows:
Additional definitions:
3.2.101
SPRAY CHAMBER
chamber in which droplets of sample in aerosol are allowed to separate so that the droplets of
necessary size can be passed onward to the burner, with the remainder draining to waste
3.2.102
GAS LOCK
device to allow drainage of waste sample liquid, and to prevent unintentional escape of gas
from the SPRAY CHAMBER through its drain outlet (see for example Figure 101)

– 6 – 61010-2-061  IEC:2003(E)
3.5.101
FLASH-BACK
event during which the flame travels back through the burner with the result that the gas in
the mixing chamber is caused to ignite.
4 Tests
This clause of Part 1 is applicable except as follows:
Additional subclauses:
4.4.2.101 Sampling probe tip
Any system designed to withdraw a sampling probe tip after sampling has been completed
shall be overridden, so as to leave the tip in its most exposed position when a sample vessel
is removed.
Exceptions:
The withdrawal system need not be overridden if the sampling probe:
a) cannot cause a HAZARD to the OPERATOR when it is exposed;
b) is designed in such a manner that no SINGLE FAULT can cause the tip to remain exposed
after sampling has been completed.
4.4.2.102 Failure, or partial failure, of the MAINS supply
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:
Additional subclause:
5.1.101 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.
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
that the installer or OPERATOR is able to c
