Ultrasonics - Power measurement - Radiation force balances and performance requirements
This International Standard - specifies a method of determining the total emitted acoustic power of ultrasonic transducers based on the use of a radiation force balance; - establishes general principles for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; -establishes limitations of the radiation force method related to cavitation and temperature rise; - establishes quantitative limitations of the radiation force method in relation to diverging and focused beams; - provides information on assessment of overall measurement uncertainties. This International Standard is applicable to: - the measurement of ultrasonic power up to 1 W based on the use of a radiation force balance in the frequency range from 0,5 MHz to 25 MHz; - the measurement of ultrasonic power up to 20 W based on the use of a radiation force balance in the frequency range 0,75 MHz to 5 MHz; - the measurement of total ultrasonic power of transducers, preferably with well-collimated beams; - the use of radiation force balances of the gravimetric type or force feedback type.

La présente Norme internationale - prescrit une méthode pour déterminer la puissance ultrasonore totale émise par des transducteurs ultrasonores, basée sur l'usage d'une balance de forces de rayonnement; - établit les principes généraux pour utiliser les balances de forces de rayonnement dans lesquelles un obstacle dénommé cible intercepte le champ acoustique à mesurer; - établit des limitations de la méthode de forces de rayonnement relatives à la cavitation et à l'élévation de la température; - établit des limitations quantitatives de la méthode de forces de rayonnement par rapport aux faisceaux divergents; - fournit des informations concernant l'évaluation des incertitudes de mesurage globales. Cette Norme internationale est applicable: - au mesurage de la puissance ultrasonore jusqu'à 1 W par utilisation d'une balance de forces de rayonnement dans la plage de fréquence de 0,5 MHz à 25 MHz; - au mesurage de la puissance ultrasonore jusqu'à 20 W par utilisation d'une balance de forces de rayonnement dans la plage de fréquence de 0,75 MHz à 5 MHz; - au mesurage de la puissance ultrasonore totale de transducteurs, avec des faisceaux possédant de préférence une bonne collimation; - à l'utilisation de balances de forces de rayonnement de type gravimétrique ou à retour de force.

This European Standard was approved by CENELEC on 2007-03-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the

Foreword
The text of document 87/325/CDV, future edition 2 of IEC 61161, prepared by IEC TC 87, Ultrasonics,
was submitted to the IEC-CENELEC parallel Unique Acceptance Procedure and was approved by
CENELEC as EN 61161 on 2007-03-01.
This European Standard supersedes EN 61161:1994 + A1:1998.
The main significant changes are:
– the main body of the standard has been restricted to normative statements;
– informative statements on corresponding aspects of ultrasonic power measurement and radiation
force balances have been collected in Annex A;
– Annexes A, D, E and F are new;
– more radiation force balance arrangements are dealt with. The new material relates particularly to
power measurement of ultrasonic physiotherapy devices.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-03-01
The following print types are used:
– requirements: roman type;
– notes: small roman type;
– words in bold in the text are defined in Clause 3.
The numbers in square brackets refer to the Bibliography (after the annexes).
Annex ZA has been added by CENELEC.
