General Information
Frequently Asked Questions
WG 3 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 87/WG 3". This committee has published 696 standards.
WG 3 develops IEC standards in the area of Information technology. Currently, there are 696 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC TS 63001:2024 provides a technique of measurement and evaluation of ultrasound in liquids for use in cleaning devices, equipment, and ultrasonic reactors. It specifies
- the cavitation measurement at frequencies between harmonics of the operating frequency f0,
- the cavitation measurement derived by integrating broadband cavitation noise energy,
- the cavitation measurement by extraction of broadband spectral components.
This document covers the measurement and evaluation of cavitation, but not its secondary effects (cleaning results, sonochemical effects, etc.). Further details regarding the generation of cavitation noise in ultrasonic baths and ultrasonic reactors are provided in Annex A.
IEC TS 63001:2024 cancels and replaces the first edition published in 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of a new method of measurement: the measurement of integrated broadband cavitation energy between two frequency bounds.

IEC TS 63001:2019 provides a technique of measurement and evaluation of ultrasound in liquids for use in cleaning devices and equipment. It specifies
• the cavitation measurement at 2,25 f0 in the frequency range 20 kHz to 150 kHz, and
• the cavitation measurement by extraction of broadband spectral components in the frequency range 10 kHz to 5 MHz.
IEC TS 63001:2019 covers the measurement and evaluation of the cavitation, but not its secondary effects (cleaning results, sonochemical effects, etc.).
