Ultrasonics - Power measurement - High intensity therapeutic ultrasound (HITU) transducers and systems
IEC 62555:2013 establishes general principles relevant to HITU fields for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; specifies a calorimetric method of determining the total emitted acoustic power of ultrasonic transducers based on the measurement of thermal expansion of a fluid-filled target; specifies requirements related to the statement of electrical power characteristics of ultrasonic transducers; provides guidance related to the avoidance of acoustic cavitation during measurement; provides guidance related to the measurement of HITU transducers of different construction and geometry, including collimated, diverging and convergent transducers, and multi-element transducers; provides guidance on the choice of the most appropriate measurement method; and provides information on assessment of overall measurement uncertainties. This International Standard is applicable to the measurement of ultrasonic power generated by HITU equipment up to 500 W in the frequency range from 0,5 MHz to 5 MHz. HITU equipment may generate convergent, collimated or divergent fields. For frequencies less than 500 kHz, no validations exist and the user should assess the uncertainties of the power measurement and measurement system at the frequencies of operation. This International Standard does not apply to ultrasound equipment used for physiotherapy, for lithotripsy for general pain relief.

La IEC 62555:2013 établit les principes généraux, applicables aux champs HITU, permettant d'utiliser les balances de forces de rayonnement dans lesquelles un obstacle (cible) intercepte le champ acoustique à mesurer; spécifie une méthode calorimétrique de détermination de la puissance acoustique totale émise par des transducteurs ultrasonores, en se fondant sur le mesurage de la dilatation thermique d'un fluide cible; spécifie les exigences relatives à la déclaration des caractéristiques de la puissance électrique des transducteurs ultrasonores; fournit des recommandations permettant d'éviter la cavitation acoustique au cours du mesurage; donne des lignes directrices pour le mesurage des transducteurs HITU de différentes constructions et géométries, y compris les transducteurs non focalisants, divergents et focalisants ainsi que les transducteurs à éléments multiples; fournit des recommandations quant au choix de la méthode de mesurage la plus appropriée; et fournit des informations concernant l'évaluation des incertitudes de mesure globales. La présente Norme Internationale s'applique au mesurage de la puissance ultrasonore générée par des appareils HITU, atteignant jusqu'à 500 W, dans la gamme des fréquences de 0,5 MHz à 5 MHz. Les appareils HITU peuvent générer des champs focalisés, non focalisés ou divergents. Il n'existe aucune validation pour les fréquences inférieures à 500 kHz. Il convient que l'utilisateur évalue les incertitudes de mesure de la puissance et du système de mesure aux fréquences de fonctionnement utilisées. La présente Norme internationale ne s'applique pas aux appareils à ultrasons utilisés pour la physiothérapie, pour la lithotritie ou pour soulager la douleur de manière générale.
Ultrazvok - Merjenje moči - Merjenje izhodne moči visokointenzivnih terapevtskih ultrazvočnih (HITU) pretvornikov in sistemov (IEC 62555:2013)
Standard EN-IEC 62555 uvaja splošna načela, pomembna za polja HITU, za uporabo ravnotežij sil sevanja, pri katerih ovira (tarča) prestreže zvočno polje, ki je predmet meritve; - določa kalorimetrično metodo za določanje skupne oddane akustične moči ultrazvočnih pretvornikov glede na merjenje toplotnega raztezanja tarč, napolnjenih s tekočino; - določa zahteve, povezane z izjavo o lastnostih električne moči ultrazvočnih pretvornikov; - nudi navodila, povezana s preprečevanjem akustične kavitacije med meritvijo; - nudi navodila, povezana z meritvijo pretvornikov HITU različnih oblik in sestavljenih na različne načine, vključno s kolimiranimi, divergentnimi in konvergentnimi pretvorniki; - nudi navodila glede izbire najbolj primerne meritvene metode; - nudi informacije glede ocenjevanja merilnih negotovosti. Ta mednarodni standard velja za merjenje ultrazvočne moči do 500 W v frekvenčnem območju od 0,5 MHz do 5 MHz, ki jo proizvaja oprema HITU. Oprema HITU lahko proizvaja konvergentna, divergentna ali kolimirana polja. Za frekvence, nižje od 500 kHz, ni preverjenih meritev, in uporabnik mora oceniti merilne negotovosti postopka merjenja moči in meritvenega sistema pri delovnih frekvencah. Ta mednarodni standard se ne uporablja za: - ultrazvočno opremo, ki se jo uporablja pri fizioterapiji za postopek litotripsije, ki blaži bolečine.
