When a breathalyser reading could influence a workplace safety decision, accuracy matters. That is why many Australian businesses look for workplace breathalysers that are designed for reliable alcohol testing and compliance-focused use. AS3547:2019 is the Australian Standard for breath alcohol testing devices, setting out requirements for performance, testing, and marking across personal, workplace, and medical screening purposes. In simple terms, it helps buyers understand whether a breathalyser has been assessed against recognised expectations for accuracy and reliability.
For workplaces, this is especially important. Breathalysers are not just devices that produce a number on a screen. They are tools used to support responsible decisions, reduce risk, and help maintain safer environments.
Key Takeaways
- AS3547:2019 sets the Australian standard for breathalyser accuracy and ensures devices meet recognised performance requirements.
- Certified breathalysers provide more reliable readings, which are critical for workplace safety and compliance.
- Proper use and regular calibration are essential to maintain accuracy and ensure consistent results over time.
- Choosing a compliant device from a trusted supplier helps reduce risk and supports safer decision making.
What Is AS3547:2019?
AS3547:2019 is the current Australian Standard for breath alcohol testing devices. It replaced AS3547:1997 and was developed to specify requirements for the performance, testing, and marking of breath alcohol testing devices. The standard applies to devices used for purposes such as personal use, workplace screening, and medical screening.
The key point is that AS3547:2019 is not simply a marketing label. It relates to how a breathalyser performs under defined testing conditions and whether the device meets recognised criteria.
For buyers, this matters because it provides a clearer way to evaluate a device beyond vague claims like “accurate” or “professional grade”. A certified device gives users more confidence that the breathalyser has been assessed against an established standard.
Why AS3547:2019 Certification Matters
Breathalysers are often used in situations where the outcome matters. For individuals, a reading may help them make a safer decision after drinking. For workplaces, it may form part of an alcohol management policy, fit-for-work process, or broader safety program.
AS3547:2019 certification matters because it supports trust. A device that has been tested to the standard gives users greater confidence that its readings are based on recognised performance expectations.
This is especially important in safety-sensitive environments such as transport, construction, mining, logistics, and manufacturing. In these industries, alcohol impairment can increase the risk of incidents, injuries, and compliance failures.
Certification also helps businesses demonstrate that they take alcohol testing seriously. While a breathalyser alone does not create a complete workplace policy, using compliant equipment can support a stronger approach to duty of care and risk management.
What Does the Standard Assess?
AS3547:2019 focuses on the performance, testing, and marking of breath alcohol testing devices. That means it looks at how a device performs, how it is tested, and how it should be identified or marked for users.
In practical terms, this can include areas such as:
- Performance requirements: whether the device can provide reliable readings under defined conditions.
- Testing requirements: how the device is assessed to confirm it meets the standard.
- Marking requirements: how compliance and device information are presented to users.
This helps separate properly tested breath alcohol testing devices from low-quality alcohol testers that may not provide consistent results. For workplaces, that difference can be significant.
A breathalyser used for staff screening, site access, or safety checks needs to deliver dependable results. If the device is inconsistent, the entire testing process becomes harder to trust.
Personal Use vs Workplace Compliance
AS3547:2019 can be relevant for both individuals and organisations, but the stakes are different.
For personal users, certification provides reassurance. If you are using a breathalyser before making a driving decision, you want to know that the reading is coming from a device built around recognised performance standards.
For workplaces, certification plays a broader role. Alcohol testing may be part of a formal safety policy, especially where employees operate machinery, drive vehicles, work at heights, or perform safety-critical tasks.
A workplace breathalyser may be used to support:
- Pre-start checks
- Random alcohol screening
- Post-incident testing
- Fit-for-work procedures
- Site safety requirements
In these contexts, the breathalyser must be more than convenient. It needs to be reliable, easy to use, and suitable for repeated professional testing.
AS3547:2019 and Breathalyser Accuracy
Certification supports confidence, but it does not remove the need for correct use and ongoing maintenance. A breathalyser reading can be affected by the quality of the sensor, calibration status, testing procedure, and user error.
This is why businesses should consider both the certification status of the device and its ongoing servicing requirements. A certified breathalyser that is not maintained correctly may become less reliable over time.
Fuel cell sensor technology is commonly preferred for professional-grade testing because it is designed to detect ethanol with a high level of specificity. This helps reduce the risk of readings being affected by other substances and supports more consistent results.

How to Check If a Breathalyser Is Certified
Not every breathalyser sold online is certified to AS3547:2019. Some products may use broad claims like “highly accurate” or “professional quality” without providing clear compliance information.
Before purchasing a breathalyser, check whether the supplier provides clear information about certification and maintenance requirements.
Look for:
- AS3547:2019 certification details
- Product documentation or certificate information
- Clear calibration requirements
- Transparent device specifications
- A reputable Australian supplier
If the product page does not clearly explain whether the device is certified, it is worth asking before buying. This is especially important for businesses purchasing devices for workplace alcohol testing.
For professional environments, documentation matters. A workplace should be able to show that its testing equipment is appropriate for the intended use and maintained according to recommended intervals.
Calibration and Ongoing Compliance
Calibration is the process used to help maintain breathalyser accuracy over time. Like any measurement device, a breathalyser can drift due to regular use, environmental conditions, and sensor ageing.
That is why calibration should be treated as part of responsible breathalyser ownership, not an optional extra.
For workplaces, calibration records can support compliance processes and internal safety documentation. If a device is used for employee screening, businesses should maintain clear records of when it was calibrated and when the next calibration is due.
Calibration intervals vary depending on the device, manufacturer, and usage conditions. Some professional devices may have defined calibration periods, which should be followed closely to maintain accuracy and reliability.
A compliance-ready approach includes choosing the right device, using it correctly, maintaining it properly, and keeping relevant service records.
Risks of Using a Non-Compliant Breathalyser
Using a non-compliant or poorly tested breathalyser can create a false sense of security. If a device produces inaccurate readings, users may make decisions based on information that is not reliable.
For individuals, this could mean thinking they are under the legal BAC limit when they are not. For workplaces, it can create gaps in safety systems and undermine trust in alcohol testing procedures.
The risks may include incorrect BAC readings, inconsistent testing outcomes, workplace safety concerns, legal exposure, and reduced confidence in internal processes.
The issue is not simply whether a breathalyser can detect alcohol. The issue is whether it can provide a reading that users can reasonably trust when the outcome matters.
How to Choose a Compliant Breathalyser
Choosing a compliant breathalyser starts with understanding how the device will be used. A personal user may need a reliable device for occasional testing, while a workplace may require a professional unit designed for frequent screening and record keeping.
For workplace environments, choose a device that supports accuracy, durability, and practical use on site. The Drager Alcotest 7000 with Bluetooth Printer is designed for professional alcohol testing and includes printer functionality for onsite record keeping, which can be valuable for workplace processes.
Businesses may also consider Breatho Professional Breathalysers for workplace screening, especially where teams need a practical device for checking staff before safety-sensitive work.
