ACMA EMCEMC Labelling Notice, RCM EMC Compliance, EMC Testing, EMC Standards, EMC Report Reviews
EMC (Electromagnetic Compatibility) compliance is legislated in Australia under the Radiocommunications Act 1992. It is mandatory for electrical and electronic devices to comply with the ACMA Radiocommunications Labelling (Electromagnetic Compatibility) Notice 2017 and applicable EMC standards.
EMC is the control of unintentional electromagnetic energy from a device that may cause interference (disruption to radio reception and electronic devices) and at the same time, operate correctly in its intended environment without being adversely affected by interference.
EME Compliance is a requirement of ACMA RCM.
Q: Why is EMC compliance important?
A: EMC compliance reduces the liklihood of causing harmful interference and disrupting access to the licenced radio spectrum, whilst ensuring that devices operate reliably in their intended environment. We rely on radiocommunications and electronics every day and it is critical that devices work in harmony.
General EMC Requirements
For RCM EMC compliance only emissions testing is mandatory. The ACMA recommends immunity testing in order to produce a more robust and reliable product however it is not mandatory. If you intend to sell your product in the EU (CE Marking) then immunity testing will be required.
Some government departments such as the DOJ (Department of Justice) in Victoria and NSW RTA (Road Traffic Authority) specify immunity testing per IEC or EN 61000-6-4 in their supplier contracts.
Harmonics and flicker per EN 61000-3-2 and EN 61000-3-3 is not required for ACMA RCM although it is required for CE Marking in the EU (EMC Directive).
There are three risk levels for RCM EMC:
- Devices that are not medium risk or high risk
- Basic, passive devices that do not pose a significant interference risk
- Battery powered devices with no external power source
- Devices without switching circuits, microelectronics, electrical motors
- Devices that are not high risk
- Devices that pose a moderate interference risk
- Generally contain microprocessors, electrical motors, switching circuits (including switch mode power supplies), non linear devices
- Battery powered with external power source (if ACMA declare it)
- Group 2 ISM equipment as described in AS/NZS CISPR 11
- Devices that pose a high interference risk
- Examples include microwave ovens, induction cookers, RF welding machines, arc welding machines and ElectroDischarge Machining (EDM) equipment
Specific EMC Requirements
Low risk: Device description; Declaration of Conformity (if labelled with RCM voluntarily)
Medium Risk: Device description, Declaration of Conformity, valid test report, label with the RCM
High Risk: Device description, Declaration of Conformity, accredited test report, label with the RCM
A Compliance Folder must be maintained that includes the necessary documents. It can be electronic or hard copy.

ACMA maintain a list of mandated EMC standards. The most applicable EMC standard for the product shall be applied.
For high risk devices the reports must be issued by an ilac accredited laboratory.
Common EMC standards include the following:
AS/NZS CISPR 32 (equivalent to EN 55032 and CISPR 32) Multimedia equipment
AS CISPR 11 (equivalent to EN 55011 and CISPR 11) Industrial, Scientific and Medical equipment
AS/NZS CISPR 12 (equivalent to EN 55012 and CISPR 12) Vehicles, boats and internal combustion engines
AS CISPR 14.1 (equivalent to EN 55014.1 and CISPR 14.1) household appliances, electric tools and similar apparatus
EN/IEC 60947-1 (and subparts) Low-voltage switch gear and control gear
AS/NZS 61000.6.3 (equivalent to EN 61000-6-3 and IEC 61000-6-3) Generic emission standard for residential, commercial and light-industrial environments
AS/NZS 61000.6.4 (equivalent to EN 61000-6-4 and IEC 61000-6-4) Generic emission standard for industrial environments
Many EN or EU standards appear on the list such as:
EN 61326-1 Electrical equipment for measurement, control and laboratory use
UN ECE Regulation 10 Motor Vehicles and accessories (ESA’s or Electronic Sub Assemblies)
EN 50270 Electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen
IEC/EN 60669-2-1 Switches for household and similar fixed electrical installations—Part 2-1: Particular requirements— electronic switches
IEC/EN 60945 Maritime navigation and radiocommunication equipment and systems— General requirements—Methods of testing and required test results
Overseas EMC Test Reports
Overseas EMC test reports (such as CE Marking EMC Directive reports) can be used, provided they are valid, written in English and adequately demonstrate that the product complies with the relevant mandated standard.
If in doubt the reports should be assessed by an expert before signing the ACMA DoC. Global Approvals can provide economical, expert EMC report review services.
Should any EMC testing be necessary Global Approvals can arrange it for you at the best possible price.
HOT TIP: If you are importing a device ask your supplier for CE marking EMC test reports!
