Full title and description

St IEC TS 63001-2024 — Measurement of cavitation noise in ultrasonic baths and ultrasonic reactors. This Technical Specification defines measurement techniques and evaluation methods for ultrasound-induced cavitation in liquids used in cleaning equipment and ultrasonic reactors; it addresses measurement of cavitation noise (including broadband energy integration and spectral extraction) but does not cover secondary effects such as cleaning performance or sonochemical outcomes.

Abstract

This document (IEC TS 63001:2024) provides standardized procedures for detecting and quantifying cavitation noise in ultrasonic baths and reactors. It specifies measurement methods at frequencies between harmonics of the operating frequency and introduces an integrated broadband cavitation-energy measurement in this edition. The specification cancels and replaces the 2019 edition and represents a technical revision to improve comparability of cavitation measurements across devices.

General information

• Status: Current Technical Specification (revised edition, replaces the 2019 edition).
• Publication date: 8 February 2024 (IEC publication date shown for the 2024 edition).
• Publisher: International Electrotechnical Commission (IEC), TC 87 Ultrasonics.
• ICS / categories: 17.140.01 (Acoustic measurements and noise abatement in general); 17.140.50 (Electroacoustics).
• Edition / version: Edition 2.0 (2024).
• Number of pages: 36 pages (IEC published document — note some national adoption documents may show slight pagination differences).

Scope

The specification describes measurement and evaluation techniques for cavitation noise generated in liquids by ultrasonic transducers in baths and reactors. It covers: measurement at frequencies between harmonics of the operating frequency; extraction of broadband spectral components; and a new method for integrated broadband cavitation-energy measurement between specified frequency bounds. It explicitly excludes assessment of secondary effects such as cleaning efficiency or sonochemistry; Annex A gives further details on cavitation-noise generation.

Key topics and requirements

• Defined measurement locations and microphone/ hydrophone positioning for reliable cavitation-noise capture.
• Procedures for spectral analysis: extraction of broadband spectral components across specified frequency bands.
• New method in the 2024 edition for integrating broadband cavitation-energy between two frequency bounds to quantify overall cavitation intensity.
• Guidance on frequency ranges of interest (harmonic-related measurements and broadband ranges relevant to ultrasonic cleaning/reactor equipment).
• Requirements for instrumentation, signal processing and reporting to allow comparability between devices and tests.

Typical use and users

This TS is intended for metrologists, test laboratories, R&D teams, equipment manufacturers (ultrasonic cleaners and reactors), and quality/assurance engineers who need repeatable, comparable measurements of cavitation noise for design validation, production testing, or research. It is also used by standards bodies and national committees adopting the IEC text as a national document.

Related standards

Relevant documents include the previous edition IEC TS 63001:2019 (cancelled by the 2024 edition), and other ultrasonic/electroacoustic measurement standards from IEC TC 87 and related ICS areas addressing ultrasonic transducers, acoustic measurements, and performance testing of ultrasonic cleaning and therapeutic devices. National adoptions (PD/DIN/ÖVE versions) reflect the IEC content with local publication details.
