Ultrasonics - Hydrophones - Part 2: Calibration for ultrasonic fields up to 40 MHz
This part of IEC 62127 specifies: - absolute hydrophone calibration methods; - relative (comparative) hydrophone calibration methods. This standard is applicable to - hydrophones used for measurements made in water and in the ultrasonic frequency range up to 40 MHz; - hydrophones employing circular piezoelectric sensor elements, designed to measure the pulsed wave and continuous wave ultrasonic fields generated by ultrasonic equipment; - hydrophones with or without a hydrophone pre-amplifier. IEC 62127-1, IEC 62127-2 and IEC 62127-3 are being published simultaneously. Together these cancel and replace IEC 60866:1987, IEC 61101:1991, IEC 61102:1991, IEC 61220:1993 and IEC 62092:2001. The contents of the corrigendum of August 2008 have been included in this copy.
Ultraschall - Hydrophone - Teil 2: Kalibrierung für Ultraschallfelder bis zu 40 MHz
Ultrasons - Hydrophones - Partie 2: Etalonnage des champs ultrasoniques jusqu'à 40 Mhz
La CEI 62127-2:2007 spécifie les méthodes d'étalonnage absolues de l'hydrophone et les méthodes d'étalonnage (comparatives) relatives de l'hydrophone. Cette norme s'applique: - aux hydrophones utilisés pour procéder à des mesures dans l'eau dans la plage de fréquences ultrasonores pouvant atteindre 40 MHz; - aux hydrophones utilisant des capteurs piézoélectriques circulaires, conçus pour mesurer les champs ultrasoniques à ondes pulsées et entretenues générés par les appareils à ultrasons; - et aux hydrophones avec ou sans préamplificateur d'hydrophone. La CEI 62127-1, la CEI 62127-2 et la CEI 62127-3 ont été publiées conjointement. Ensemble, elles annulent et remplacent la CEI 60866:1987, la CEI 61101:1991, la CEI 61102:1991, la CEI 61220:1993 et la CEI 62092:2001.

Ultrazvok - Hidrofoni - 2. del: Kalibracija za ultrazvočna polja do 40 MHz (IEC 62127-2:2007)
Ta del standarda IEC 62127 določa: absolutne metode kalibracije hidrofonov; relativne (primerjalne) metode kalibracije hidrofonov. Priporočila in sklici na sprejeto literaturo so podani za številne relativne in absolutne metode kalibracije v frekvenčnem območju, ki ga zajema ta standard. Ta standard se uporablja za hidrofone, ki se uporabljajo za meritve, opravljene v vodi in ultrazvočnem frekvenčnem območju do 40 MHz; hidrofone, ki uporabljajo krožne piezoelektrične senzorne elemente in so zasnovani za merjenje ultrazvočnih polj z impulznimi in neprekinjenimi valovi, ki jih ustvari ultrazvočna oprema; hidrofone s hidrofonskim predojačevalnikom ali brez njega.
