AS NZS 4713-2002 PDF

Full title and description

AS/NZS 4713:2002 — Ultrasonics — Physiotherapy systems — Performance requirements and methods of measurement in the frequency range 0.5 MHz to 5 MHz. This joint Australian/New Zealand adoption reproduces IEC 61689 (with national variations) and sets performance and measurement requirements for ultrasonic physiotherapy equipment operating in the 0.5–5 MHz band.

Abstract

Specifies methods of measurement and characterization of the output performance of ultrasonic physiotherapy equipment (reference and routine test methods), the characteristics manufacturers should declare, requirements and safety considerations for the ultrasonic field produced, and acceptance criteria for routine tests. The standard does not address therapeutic efficacy or methods of clinical use.

Scope

Applies to ultrasonic equipment designed for physiotherapy that contains an ultrasonic transducer generating continuous or quasi‑continuous (e.g., tone burst) ultrasonic energy in the frequency range 0.5 MHz to 5 MHz. The scope covers measurement methods (reference and routine), declared performance characteristics, performance/safety requirements for the ultrasonic field and acceptance criteria for routine tests. It excludes clinical guidance and therapeutic value or methods of use. The AS/NZS adoption reproduces IEC 61689 with national (ZZ) variations.

Key topics and requirements

• Performance requirements for ultrasonic physiotherapy transducers and systems (output levels, stability, reproducibility).
• Reference and routine methods of measurement (hydrophone and field characterization techniques).
• Declared manufacturer characteristics (frequency, effective radiating area, rated output, beam characteristics).
• Safety-related field specifications and limits relevant to device output and acoustic exposure.
• Acceptance criteria for routine testing and production checks.
• National variations/annex (ZZ) modifying the IEC base text for Australia/New Zealand conditions.

Typical use and users

Used by medical device manufacturers (design and compliance teams), test laboratories and calibration facilities, regulatory and conformity assessment bodies, procurement/specification engineers for physiotherapy equipment, and clinical engineers responsible for acceptance testing and maintenance of ultrasonic physiotherapy devices.

Related standards

Directly related to IEC 61689 (base international standard for ultrasonic physiotherapy systems). Other related standards include relevant medical electrical equipment standards (for example standards in the AS/NZS 3200 series and IEC 60601 family where applicable) and later editions/revisions of IEC 61689. Users seeking current measurement or safety requirements should consult the latest IEC 61689 editions and applicable national medical-device standards.

FAQ

Q: What is this standard?

A: AS/NZS 4713:2002 is the Australian/New Zealand adoption of an IEC standard that specified performance requirements and measurement methods for ultrasonic physiotherapy systems operating between 0.5 MHz and 5 MHz.

Q: What does it cover?

A: It covers test methods (reference and routine), field and output performance characteristics, declared manufacturer parameters, safety-related field specifications and acceptance criteria for routine production or maintenance testing. It does not cover clinical usage or therapeutic efficacy.

Q: Who typically uses it?

A: Manufacturers, test laboratories, conformity assessors, clinical/biomedical engineers, and procurement/specification personnel for physiotherapy and rehabilitation equipment.

Q: Is it current or superseded?

A: AS/NZS 4713:2002 has been withdrawn (published 19 December 2002 and listed as withdrawn without replacement by the standards body). For current international guidance, consult later editions of IEC 61689 (subsequent revisions exist) and relevant medical-electrical device standards.

Q: Is it part of a series?

A: It is the AS/NZS adoption of the IEC 61689 series (international standard for ultrasonic physiotherapy systems). It sits alongside other AS/NZS and IEC standards covering medical electrical equipment and particular requirements for therapeutic/diagnostic devices.

Q: What are the key keywords?
