IEC 61307:2011

Industrial microwave heating installations - Test methods for the determination of power output

IEC 61307:2011 specifies test methods for the determination of the available microwave output power and the efficiency of frequency conversion from the electrical input in industrial microwave heating installations. This standard also specifies test methods for assessing the microwave power deposition in the microwave workload - the microwave workload power, in microwave-only installations. This standard is applicable to industrial microwave heating equipment and installations in the frequency range from 300 MHz to 300 GHz. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) it covers how to measure not only the microwave power output of all typical equipment designs, but also the system efficiency, including the standby and hibernation modes;
b) the handling of the former A and B types of equipment is replaced by measurements of the available microwave power output and microwave workload power, respectively.

Installations industrielles de chauffage à hyperfréquence - Méthodes d'essais pour la détermination de la puissance de sortie

La CEI 61307:2011 spécifie les méthodes d'essai permettant de déterminer la puissance hyperfréquence de sortie disponible et le rendement de la conversion de fréquence à partir de l'entrée électrique dans les installations industrielles de chauffage à hyperfréquence. La présente norme spécifie également des méthodes d'essai permettant d'évaluer l'apport de puissance hyperfréquence dans la charge de travail micro-onde, la puissance hyperfréquence de la charge de travail dans les installations uniquement à hyperfréquence. La présente norme est applicable aux équipements et aux installations industrielles de chauffage à hyperfréquence dans la gamme de fréquences allant de 300 MHz à 300 GHz. Cette troisième édition annule et remplace la deuxième édition parue en 2006. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) elle couvre la manière de mesurer non seulement la puissance hyperfréquence de sortie de toutes les conceptions types d'équipement, mais aussi le rendement des systèmes, en incluant les modes de veille et d'hibernation;
b) le traitement des types antérieurs d'équipement A et B est respectivement remplacé par des mesures de la puissance hyperfréquence de sortie disponible et de la puissance hyperfréquence de la charge de travail.

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 61307 has been prepared by IEC technical committee 27:
Industrial electroheating.
This third edition cancels and replaces the second edition published in 2006. It constitutes a
technical revision .
This edition includes the following significant technical changes with respect to the previous
edition:-
a) it covers how to measure not only the microwave power output of all typical equipment
designs, but also the system efficiency, including the standby and hibernation modes;
b) the handling of the former A and B types of equipment is replaced by measurements of the
available microwave power output and microwave workload power, respectively.

TEST METHODS FOR THE DETERMINATION
OF POWER OUTPUT
1 Scope
This International Standard specifies test methods for the determination of the available
microwave output power and the efficiency of frequency conversion from the electrical input in
industrial microwave heating installations.
This standard also specifies test methods for assessing the microwave power deposition in
the microwave workload – the microwave workload power, in microwave-only installations.
This standard is applicable to industrial microwave heating equipment and installations in the
frequency range from 300 MHz to 300 GHz.
This standard relates to industrial microwave heating equipment operating under normal load.
This standard does not apply to appliances for household and similar use (covered by
IEC 60335-2-25), commercial use (covered by IEC 60335-2-90) or laboratory use (covered by
IEC 61010-2-010).
