IEC 60565-2:2019

IEC 60565-2:2019 provides the technical reference for underwater acoustics hydrophone calibration with a focus on low frequency pressure calibration. It is relevant for laboratories, engineering teams, and procurement specialists that need a reliable basis for technical assessment, verification activities, and documented evaluation of hydrophone performance. For organizations working with measurement systems in underwater environments, the document supports more consistent calibration practice and helps align compliance workflows with a defined engineering specification.

What is IEC 60565-2:2019?

IEC 60565-2:2019 is the second part of the hydrophone calibration series and addresses procedures for low frequency pressure calibration. Based on the official title, its purpose is to define how calibration should be carried out so that hydrophones can be assessed in a controlled and repeatable way. This is important for technical validation, conformity assessment preparation, and laboratory evaluation where measurement traceability and operational consistency are expected.

Applications of IEC 60565-2:2019

This document is typically used in underwater acoustics laboratories, test facilities, and engineering environments that calibrate hydrophones for measurement or monitoring tasks. It may support product evaluation, equipment qualification, and quality workflows where low frequency acoustic pressure measurements need documented confidence. Organizations involved in marine instrumentation, research, and specialized testing workflows can use it as a practical compliance reference when preparing calibration records or reviewing procurement requirements.

Why is IEC 60565-2:2019 important?

Accurate hydrophone calibration affects measurement quality, test consistency, and the credibility of engineering data. IEC 60565-2:2019 helps teams reduce risk by providing a defined approach for low frequency pressure calibration, which can improve repeatability across laboratories and support regulatory preparation or audit readiness. For buyers, engineers, and compliance professionals, it offers a clear basis for technical review, conformity assessment, and documentation control when calibration performance must be justified.
