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 fourth edition cancels and replaces the third edition published in 2015. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) adaptation of changes introduced by Amendment 1 of IEC 61010-1;
b) added tolerance for stability of AC voltage test equipment to Clause 6;
---------------------- Page: 5 ----------------------
– 4 – IEC 61010-2-061:2018 © IEC 2018

c) added requirement for interlock systems containing electric/electronic or programmable

components to Clause 15.
The text of this International Standard is based on the following documents:
CDV Report on voting
66/643/CDV 66/668/RVC

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the IEC 61010 series, under the general title, Safety requirements for

electrical equipment for measurement, control, and laboratory use, may be found on the IEC

website.

This Part 2-061 is intended to be used in conjunction with IEC 61010-1. It was established on

the basis of the third edition (2010) and its Amendment 1 (2016).

This Part 2-061 supplements or modifies the corresponding clauses in IEC 61010-1 so as to

convert that publication into the IEC standard: Particular 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 and additional list

items are lettered from aa).

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://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.

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.
