Radiation protection instrumentation - Recommended climatic, electromagnetic and mechanical performance requirements and methods of tests

IEC 62706:2019 recommends the climatic, mechanical and electromagnetic performance requirements and methods of test for radiation protection instrumentation. This document also provides guidance regarding the setup of test equipment and instruments under test (IUT) for certain tests.
The object of this document is to define, for design and test purposes, the environments in which radiation protection instrumentation may be exposed. The environments addressed by this document are applicable to body-worn (e.g., personal radiation detectors, backpack, and dosemeters), handheld, transportable, mobile, and installed instrumentation.
This second edition cancels and replaces the first edition, issued in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of more details to selected methods of test;
b) revised radio frequency testing requirements based on measurements made at various locations;
c) added equipment and instrument setup guidance and recommendations.

Instrumentation pour la radioprotection - Exigences recommandées en matière de performances climatiques, électromagnétiques et mécaniques et méthodes d'essai

L'IEC 62706:2019 le présent document fournit des recommandations concernant les exigences de performances climatiques, mécaniques et électromagnétiques et les méthodes d'essai pour les instruments de radioprotection. Le présent document fournit également des recommandations concernant la configuration des équipements et instruments soumis à l'essai (IUT), pour certains essais.
L'objectif du présent document est de définir, pour les besoins de la conception et des essais, les environnements dans lesquels peuvent être exposés des instruments de radioprotection. Les environnements traités par le présent document sont applicables aux instruments portés sur le corps (par exemple, détecteurs individuels de rayonnement, dispositifs dorsaux et dosimètres), tenus à la main, transportables, mobiles et installés.
Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) ajout d'informations supplémentaires à des méthodes d'essai choisies;
b) exigences révisées en matière d'essais de radiofréquence, sur la base de mesures effectuées à divers emplacements;
c) guide et recommandations de configuration concernant les équipements et instruments ajoutés.

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 62706 has been prepared by subcommittee 45B: Radiation

protection instrumentation, of IEC technical committee 45: Nuclear instrumentation.

This second edition cancels and replaces the first edition, issued in 2012. This edition

constitutes a technical revision.

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

edition:
a) addition of more details to selected methods of test;

b) revised radio frequency testing requirements based on measurements made at various

locations;
c) added equipment and instrument setup guidance and recommendations.

INTRODUCTION

Radiation protection instrumentation including those instruments used for the detection and

identification of radioactive material and radionuclides are used in many different

environments. They are typically exposed to different temperatures, humidity levels,

electromagnetic fields, and mechanical stresses such as shock and vibration during normal

use. Radiation detection instrumentation may be worn on the body, handheld, mounted to a

vehicle, transported from location to location, or installed. All the conditions associated with

these very different uses are considered when developing instrument-specific requirements.

To ensure consistency between standards, this climatic, electromagnetic, and mechanical

performance requirements standard was established.
