IEC TS 63001:2019 PDF

Overview

IEC TS 63001:2019 - Measurement of cavitation noise in ultrasonic baths and ultrasonic reactors is a Technical Specification from the International Electrotechnical Commission (IEC) that defines techniques for measuring and evaluating ultrasound-induced cavitation in liquids used for cleaning devices and equipment. The specification focuses on acoustic measurement of cavitation (cavitation noise) and its spectral components; it does not address secondary effects such as cleaning efficacy or sonochemical reactions.

Key Topics and Requirements

• Measurement methods
  • Cavitation measurement at 2.25·f0 for operating frequencies in the 20 kHz to 150 kHz range (normative, Annex B).
  • Cavitation measurement by extraction of broadband spectral components covering 10 kHz to 5 MHz (normative, Annex D).
• Instrumentation and calibration
  • Use of hydrophones (sensitivity, calibration, environment compatibility) and spectral analysers to capture cavitation noise.
  • Requirements for hydrophone end-of-cable loaded sensitivity and calibration procedures.
• Measurement procedures
  • Reference measurements, control of environmental conditions (temperature, liquid chemistry), and in‑situ monitoring techniques.
  • Methods to identify direct-field acoustic pressure, subtract the direct-field component, and separate stable vs transient cavitation spectral features.
• Data treatment and validation
  • Compensation for extraneous noise and validation steps to ensure extracted spectral components reflect cavitation phenomena.
• Scope limits
  • The standard covers only cavitation measurement and evaluation - it explicitly excludes direct assessment of cleaning results or sonochemical effects.

Applications and Who Uses It

IEC TS 63001:2019 is intended for professionals and organizations involved in ultrasonic cleaning and ultrasonic reactor validation:

• Manufacturers of ultrasonic baths, reactors, and transducers - for product characterization and quality control.
• Test laboratories and calibration facilities - for standardized cavitation noise measurement and hydrophone calibration practices.
• Industrial process engineers and QA teams - to monitor cavitation as part of process control for cleaning or surface treatment.
• Hospitals and sterilization services - for validation and documentation of ultrasonic cleaning equipment.
• Researchers studying cavitation phenomena, acoustic streaming, and transducer performance.
