Annotation of standard text IEC 60565-2-ed.1.0 :
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 specifie les methodes d’etalonnage a basse pression de frequence des hydrophones a des frequences comprises entre 0,01 Hz et plusieurs kilohertz selon la methode d’etalonnage. L’IEC 60565-2:2019, avec l’IEC 60565-1, remplace la deuxieme edition de l’IEC 60565 parue en 2006. Cette edition constitue une revision technique. L’IEC 60565-2:2019 inclut les modifications techniques majeures suivantes par rapport a ledition precedente: 1) L’IEC 60565 a ete divisee en deux parties: • Partie 1: Procedures pour l’etalonnage en champ libre; • Partie 2: Procedures pour l’etalonnage a basse pression de frequence (le present document). 2) Une methode d’etalonnage relatif a ete ajoutee a l’Article 8: Etalonnage par compensation piezoelectrique. 3) Une methode d’etalonnage relatif a ete ajoutee a l’Article 11: Etalonnage par colonne vibrante. 4) L’Article 12: Etalonnage par transducteur de pression statique a ete ajoute. 5) L’Annexe A: Circuit equivalent du systeme d’excitation pour l’etalonnage avec une colonne vibrante, a ete supprimee. 6) Les paragraphes 9.6, 9.7 et 9.8 ont ete deplaces pour constituer une nouvelle Annexe A: Methodes d’etalonnage par coupleur acoustique evolue.
