IEC TS 63001:2024

Overview

IEC TS 63001:2024 - Measurement of cavitation noise in ultrasonic baths and ultrasonic reactors specifies standardized techniques to measure and evaluate ultrasound-induced cavitation in liquids used for cleaning devices, equipment and ultrasonic reactors. This second edition (2024) cancels and replaces IEC TS 63001:2019 and introduces a significant technical change: a new method to measure integrated broadband cavitation energy between two frequency bounds. The specification addresses cavitation noise measurement methods and instrumentation, but does not cover secondary effects such as cleaning results or sonochemical outcomes.

Key Topics

• Measurement methods
  • Cavitation measurement at frequencies between harmonics of the operating frequency f0.
  • Cavitation measurement derived by integrating broadband cavitation noise energy (new in 2024).
  • Cavitation measurement by extraction of broadband spectral components from the acoustic spectrum.
• Instrumentation and requirements
  • Use and calibration of hydrophones, analyser selection and calibration, and hydrophone-environment compatibility.
  • Procedures for analyser settings covering transient and stable cavitation spectra.
  • Controls for temperature, liquid chemistry and electrical interference during measurements.
• Measurement procedures
  • Reference and in-situ monitoring measurement workflows, environmental control, and validation steps.
  • Normative and informative annexes with worked examples and background on cavitation noise generation (Annex A).
• Normative annexes (examples): methods at specific spectral positions (e.g., 2.25 f0), broadband integration, and spectral component extraction.

Applications

IEC TS 63001:2024 is practical for:

• Manufacturers of ultrasonic baths and ultrasonic reactors validating device cavitation performance.
• Test and calibration laboratories performing acoustic and cavitation characterization.
• R&D teams and acoustic engineers optimizing transducers, power settings and bath geometry.
• Quality control and process engineers using in‑situ monitoring to ensure consistent cavitation energy during production cleaning.
• Regulatory bodies and standards committees referencing objective cavitation measurement methods.

The standard enables reproducible measurement of cavitation noise for device comparison, lifecycle testing, and process control - without making claims about cleaning efficacy or chemical effects.
