Underwater acoustics - Hydrophones - Calibration of hydrophones - Part 2: Procedures for low frequency pressure calibration

Edition date: 2019-09-19
In Force
Available languages: English, French
Summary: IEC 60565-2:2019 specifies the methods for low frequency pressure calibration of hydrophones at frequencies from 0,01 Hz to several kilohertz depending on calibration method.
IEC 60565-2:2019, together with IEC 60565-1, replaces the second edition of IEC 60565 published in 2006. This edition constitutes a technical revision.
IEC 60565-2:2019 includes the following significant technical changes with respect to the previous edition.
1) IEC 60565 has been divided into two parts:
• Part 1: Procedures for free-field calibration;
• Part 2: Procedures for low frequency pressure calibration (this document).
2) A relative calibration method has been added to Clause 8: Calibration by piezoelectric compensation.
3) A relative calibration method has been added to Clause 11: Calibration by vibrating column.
4) Clause 12: Calibration by static pressure transducer, has been added.
5) Annex A: Equivalent circuit of the excitation system for calibration with a vibrating column, has been deleted.
6) Subclauses 9.6, 9.7 and 9.8 have been moved to form a new Annex A: Advanced acoustic coupler calibration methods.

L’IEC 60565-2:2019 spécifie les méthodes d’étalonnage à basse pression de fréquence des hydrophones à des fréquences comprises entre 0,01 Hz et plusieurs kilohertz selon la méthode d’étalonnage.
L’IEC 60565-2:2019, avec l’IEC 60565-1, remplace la deuxième édition de l’IEC 60565 parue en 2006. Cette édition constitue une révision technique.
L’IEC 60565-2:2019 inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
1) L’IEC 60565 a été divisée en deux parties:
• Partie 1: Procédures pour l’étalonnage en champ libre;
• Partie 2: Procédures pour l’étalonnage à basse pression de fréquence (le présent document).
2) Une méthode d’étalonnage relatif a été ajoutée à l’Article 8: Étalonnage par compensation piézoélectrique.
3) Une méthode d’étalonnage relatif a été ajoutée à l’Article 11: Etalonnage par colonne vibrante.
4) L’Article 12: Etalonnage par transducteur de pression statique a été ajouté.
5) L’Annexe A: Circuit équivalent du système d’excitation pour l’étalonnage avec une colonne vibrante, a été supprimée.
6) Les paragraphes 9.6, 9.7 et 9.8 ont été déplacés pour constituer une nouvelle Annexe A: Méthodes d’étalonnage par coupleur acoustique évolué.
