Ultrasonics - Hydrophones - Part 3: Properties of hydrophones for ultrasonic fields

IEC 62127-3:2022 is available as IEC 62127-3:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62127-3:2022 specifies relevant hydrophone characteristics. This document is applicable to: - hydrophones employing piezoelectric sensor elements, designed to measure the pulsed and continuous wave ultrasonic fields generated by ultrasonic equipment; - hydrophones used for measurements made in water; - hydrophones with or without an associated pre-amplifier. IEC 62127-3:2022 cancels and replaces the first edition published in 2007 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) The upper frequency limit of 40 MHz has been removed. b) Hydrophone sensitivity definitions have been changed to recognize sensitivities as complex-valued quantities. c) Procedures to determine the effective hydrophone size have been changed according to the rationale outlined in Annex B. d) Requirements on the frequencies for which the effective hydrophone size shall be provided have been changed to achieve practicality for increased frequency bands. e) The new Annex B and Annex C have been added. f) Annex A has been updated to reflect the changes of the normative parts.

Ultrazvok - Hidrofoni - 3. del: Lastnosti hidrofonov za ultrazvočna polja (IEC 62127-3:2022)

Standard IEC 62127-3:2022 je na voljo kot IEC 62127-3:2022, ki vsebuje mednarodni standard in njegovo različico z revizijami, ki prikazujejo vse spremembe tehnične vsebine v primerjavi s prejšnjo izdajo. Standard IEC 62127-3:2022 določa ustrezne lastnosti hidrofonov. Ta dokument se uporablja za:
– hidrofone, ki uporabljajo piezoelektrične senzorne elemente in so zasnovani za merjenje ultrazvočnih polj z impulznimi in neprekinjenimi valovi, ki jih ustvari ultrazvočna oprema;
– hidrofone, ki se uporabljajo za izvajanje meritev v vodi;
– hidrofone s povezanim predojačevalnikom ali brez njega.
Standard IEC 62127-3:2022 razveljavlja in nadomešča prvo izdajo, objavljeno leta 2007 in dopolnilo 1:2013. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) Zgornja mejna vrednost frekvence 40 MHz je bila odpravljena.
b) Opredelitve občutljivosti hidrofonov so bile spremenjene tako, da so občutljivosti prepoznane kot kompleksno ovrednotene količine.
c) Postopki za določitev efektivne velikosti hidrofonov so bili spremenjeni v skladu z utemeljitvijo, opisano v dodatku B.
d) Zahteve glede frekvenc, za katere je treba zagotoviti efektivno velikost hidrofonov, so bile spremenjene, da se doseže praktičnost za povečane frekvenčne pasove.
e) Dodan je bil nov dodatek B in dodatek C.
f) Dodatek A je bil posodobljena tako, da odraža spremembe normativnih delov.

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 prep
