Emissions from electronic devices have been a growing concern in recent years, and many companies are now seeking to meet new emission regulations. Pre-compliance EMC testing is the process of assessing emissions before these regulations go into effect. 

This blog post will discuss what pre-compliance EMC testing entails and how it can help your company stay ahead of regulation changes. 

What Is Pre-Compliance EMC Testing?

Pre-compliance EMC testing  (or electromagnetic compatibility testing) is a method for measuring electromagnetic interference from various devices. It assesses how well an item works in its environment for its specific purpose before it goes into production on a larger scale. 

It also helps companies identify potential health risks or environmental hazards from using their products so changes can be made prior to releasing them onto public markets where consumers will use these goods all day long.

The purpose behind pre-compliance EMC testing is twofold: firstly, these types of tests are important so that if any issues arise with your device or its software while it’s operating in real-world environments (such as at home), then problems have already been identified during development rather than after deployment. 

Secondly, EMC standards help ensure compatibility across all electronic devices regardless of their manufacturer which means less headaches when setting up networks.

Therefore, pre-compliance EMC testing is a way to ensure that the systems are not just meeting all of their technical requirements, but also comply with industry standards. By checking the frequency and strength of these emissions, you can be sure that your device will not interfere with other electronics or broadcast signals in an unintended way. 

What Is The Importance Of Pre-Compliance EMC Testing?

The importance of pre-compliance EMC testing is significant because it ensures that your equipment will be able to function as expected in a working environment. This type of testing also helps you identify and address potential hazards before they become an issue, which can save time and money by preventing the need for more costly repairs later on. 

Without a pre-compliance EMC test, an organisation risks having its products labelled as “non-compliant,” which could lead to costly product recalls or even legal action from customers who have purchased faulty hardware without warning signs of quality control issues on the outside of the packaging.

What Are The Types Of Pre-Compliance EMC Testing?

Generally, there are two types of EMC testing: emissions tests and immunity tests.

1). Emissions Test

The EMC emissions testing process is a procedure that monitors the amount of electromagnetic interference (EMI) emitted from an electronic device. This test measures electrical or magnetic fields, such as those generated by power lines, radio transmitters and even thunderstorms to determine how much energy they emit into their environment. 

The goal is for any emitted waves to be at safe levels so they will not have adverse effects on other electronic devices that are in close proximity like radios and televisions. If there are too many fluctuations detected during this type of study then the company may need some adjustments before releasing new products onto store shelves!

2). Immunity Test

While emissions tests measure the amount of EMI emitted from an electronic device, an EMC immunity test ensures the device is robust enough to withstand electromagnetic interference. This can be an integral part of ensuring your IT infrastructure will work in any environment, as different environments may have stronger or weaker signals.

An immunity test protects against both unintentional or malicious electromagnetic emissions from electronic devices as well as more complex situations such as designing for mobile environments where multiple antennas are present, etc

What Are The Benefits Of Pre-Compliance EMC Testing?

Pre-compliance testing is an important step in making sure your device doesn’t have an issues. The critical benefits of pre-compliance EMC testing include: 

  • Identify major problems early on so they can be fixed quickly without needing expensive fixes later down the road.
  • Provide consumers with peace of mind knowing their purchase has been tested thoroughly by qualified professionals.
  • Ensure that products are free from EMI which could lead them to fail certification examinations after distribution into stores around the world.
  • Reduce the possibility of product recall which can be very costly.

How To Know If You Need Pre-Compliance EMC Testing

There are several factors that will determine if your product needs pre-compliance EMC testing. In the world of EMC testing, it is very important that you know what your product should be tested for before going through all of the trouble. 

The best way to figure out if a device requires pre-compliance EMC testing is by checking with the Australian Communications and Media Authority (ACMA). They can help determine whether or not an electromagnetic compatibility test needs to occur prior to finalising production on any given item.

Another way to start is by answering these questions: Can a fault in your device interfere with another electronic device or other systems within its operating environment, including medical devices and industrial controls? Is it possible that interference generated from your equipment will affect users while they are using wireless communication (e.g., cell phone), navigation services (GPS), and emergency service communications?

If you answered yes to either one then chances are high that you need compliance testing done before sale!


The basics of pre-compliance EMC testing are not difficult to understand. There are just a few things you need to know in order to start the process off on the right foot and ensure that your product is safe for use by customers in Australia or around the world if you are exporting your products.
