If you manage medical equipment in a healthcare facility, workplace, or aged care setting in Australia, you have likely come across AS/NZS 3551 referenced in a compliance document, a service contract, or an audit checklist. Here is what it actually is and what it means for equipment you own.
What AS/NZS 3551 covers
AS/NZS 3551 is the joint Australian and New Zealand Standard for the management of medical devices. It sets out a framework for how medical equipment should be managed across its working life, from initial acceptance testing through to routine maintenance, calibration, repair, and eventual decommissioning.
The standard applies broadly to electromedical equipment, meaning devices that connect electrically to a patient or are used in patient care and diagnosis. That covers a wide range of equipment, from AEDs and patient monitors through to infusion pumps, ventilators, and diagnostic devices.
Why it exists
Medical devices degrade with use and time. Batteries lose capacity, seals perish, calibration drifts, and components wear. A device that worked correctly when purchased is not guaranteed to work correctly two, three, or five years later without maintenance. AS/NZS 3551 exists to give facilities and businesses a structured, documented approach to managing that risk, rather than leaving equipment reliability to chance.
What compliance actually involves
The standard is broad and facility specific requirements vary, but the core elements that apply across most settings are:
- An equipment register. A documented inventory of medical devices, including make, model, serial number, and location.
- Risk classification. Devices are typically categorised by clinical risk, which determines how frequently they need inspection and testing.
- Scheduled maintenance and testing. Regular inspection against manufacturer specifications, not just a visual check.
- Documented records. Every test, service, and repair needs a dated record. This is the evidence that maintenance obligations have actually been met, not just assumed.
- Competent personnel. Testing and servicing should be performed by people with appropriate biomedical engineering training and equipment, not general handypersons.
Where this matters most for smaller organisations
Large hospitals typically have in-house biomedical engineering departments managing this as a matter of course. Where it more commonly gets missed is smaller organisations, workplaces with an AED or two, aged care facilities, GP clinics, and businesses that own equipment but do not have dedicated biomedical staff.
A common and costly misunderstanding: the self-test light on an AED confirms the unit powers on. It does not verify delivered shock energy, and it is not a substitute for the kind of testing AS/NZS 3551 describes. We cover this specific gap in why your AED needs annual testing.
How this connects to your general WHS obligations
AS/NZS 3551 sits alongside, and is often referenced by, general Work Health and Safety obligations. A code of practice or Australian Standard is generally admissible as evidence of what is known about a hazard and reasonably practicable ways of managing it. If equipment fails and you cannot produce testing and maintenance records consistent with the relevant standard, that is a difficult position to defend, whether or not compliance with AS/NZS 3551 is specifically mandated in your jurisdiction for your type of business.

Getting compliant equipment testing
Vectr Medical is operated by NATA-certified biomedical engineers with over 40 years of combined experience. We provide testing, calibration, and maintenance services consistent with AS/NZS 3551 requirements, including:
- AED testing and certification, with a signed calibration certificate for your compliance records
- Equipment register support and documented service history
- Testing performed with specialised biomedical testing equipment, not general electrical safety testing alone
If you are not sure whether your current equipment maintenance meets AS/NZS 3551 requirements, or you have never had a formal testing schedule in place, contact us at joe@novabiomedical.com.au or 1300 723 900 and we can talk through what your specific equipment and setting actually needs.
