EMC Testing Automotive Components

Importance Of Electrical And EMC Testing For Automotive Components

Are you involved in manufacturing automotive components? Do you know the importance of electrical and EMC testing for automotive components?

If you manufacture any automotive component that contains electronic circuitry inside, most probably, the component will emit electromagnetic waves when it’s in operation.

These waves are quite similar to radio, TV, and microwaves. Most of the time, these emissions are strong enough to affect the operation of other electronic equipment in the vicinity.

That’s why Electromagnetic Compatibility (EMC) Testing is mandatory for such components to make sure the emissions from such components fall within the electromagnetic spectrum.

This article provides information on the importance of electrical and EMC testing for automotive components.

What Is EMC Testing?

All electrical and electronic devices including automotive components have the potential to transmit electromagnetic fields.

There is a huge risk of these devices interfering with each other due to the proliferation of electronic devices in everyday life.

There have been many cases where automotive components have been recalled or withdrawn from the market due to the high level of electromagnetic interference.

That’s where Electromagnetic Compatibility (EMC) Testing becomes important. The Australian Government has adopted stringent laws to prevent the occurrence of EMC problems.

International standards relating to EMC testing have been set for all countries to observe for all electronic components released to the market. EMC testing is mandatory for all electronic components manufactured in Australia.

Why Care About EMC Testing?

Whether you are a manufacturer of automotive electronic components or any other electronic products, you cannot release these products to the market without a certification saying it has passed EMC testing services.

This testing is mandatory for all electronic components manufactured in Australia, imported to the country or exported from Australia.

The certificate should state that the electromagnetic emissions are within the range allowed for the operation of other similar products.

That’s why you need to find a reliable EMC testing service in Australia to test your electronic products.

What Is Pre-Compliance Testing?

Pre-compliance testing is important to reduce the costs of redesigning products due to the failure of EMC testing. Pre-compliance testing is conducted during the product development stage.

You can change anything in the product that doesn’t comply with EMC rules and regulations by pre-testing the product.

That’s why you need to make use of pre-compliance EMC testing for all your automotive electronic components.

The most common pre-testing is emission testing. It’s crucial for the final EMC test for certification. This test is usually done in the plant or the manufacturer’s location.

This test will measure the product emissions and help adjust it to meet the required standards.

The most important benefit of pre-compliance testing is the ability to have a less problematic EMC testing process at the final stage of product development.

This will prevent huge losses to your company due to product return, product re-design, and repeat tests.

Why Is EMC Testing Necessary?

Why Is EMC Testing Necessary?

Are you involved in the manufacture or importation of any products that contain electronic components?

If so, it is important to note that you are required to subject these products to EMC testing for purposes of compliance or due diligence or both.

What is EMC testing supposed to achieve? This is the main question that comes to mind after you find out that it is necessary. This testing helps provide product assurance in two ways:

  • For starters, this testing will help guarantee that your product will be able to function as intended when exposed to electromagnetic disturbances that normally characterise the operating environment it is designed for.
  • Secondly, EMC testing is also meant to guarantee that the product will be able to operate efficiently without producing electromagnetic interference that is beyond the acceptable levels for that type of device. This is meant to assure users that the device’s operation will not interfere with the operation of other devices within the same operating environment.

Now that you know what EMC testing focuses on, read on to find out more about the main reasons why it is necessary.

Safeguarding Electromagnetic Spectrum

Over the years, the number of electronic devices that emit electromagnetic waves as electric energy flows through their circuitry has been on a sharp increase.

Combine that with a limited magnetic spectrum which is also required for important applications involving the use of microwave signals, radio waves and x-ray machines among others has created the need to limit unnecessary use of this limited resource.

Simply put, to ensure that important operations requiring the use of the limited electromagnetic spectrum continue uninterrupted, all electronic devices must be tested to ensure that they only occupy as much of this limited resource as necessary, if any.

Product Quality

As previously mentioned, EMC testing is meant to guarantee that the products in question deliver the intended level of performance without being affected by interference from other electronic devices and components encountered in its normal working environment.

In case a product’s performance is found to be affected by the electromagnetic interference produced by other electronic devices within its working environment, then you as the manufacturer or importer cannot provide assurance of its quality to the intended end-users in its current state.

Safety

To follow up on the above point, EMC testing is also essential for safety purposes. The failure of some electrical components and devices can expose workers and the public to serious safety risks.

EMC testing helps prevent such problems by ensuring that the electromagnetic interference produced or absorbed by the product under consideration does not present a risk of failure of the device or other devices in its intended area of operation.

Compliance

Due to the importance of maintaining the integrity of the finite electromagnetic spectrum as well as ensuring product quality and safety during use, the government has put in place various EMC regulations that must be satisfied by all manufacturers and importers of products containing electronic components.

EMC testing can be used to establish whether your product complies with these safety and quality guidelines.

Failure to comply with the necessary EMC guidelines, as set out by the relevant government authorities, before introducing your product into the market can lead to serious legal issues.

Conclusion

All electronic components produce electromagnetic interference when current flows through their circuits. This interference can affect the proper operation of other electronic devices within your device’s area of operation.

Alternatively, your device may also be affected by electromagnetic interference from other devices already in use. To guarantee electronic product operation, safety and compliance with the law, EMC testing is necessary.

EMC Testing And Certification

All About EMC Testing & Certification – Electrical Product Testing

Have you built an electronic device that meets market demands? Are you confident the device radiates very little energy and doesn’t interfere with other electronic devices? If you’re not sure of the answers to these questions, please read below for more.

The only way of knowing that your electronic device doesn’t interfere with other electronic devices is to conduct an EMC test on your electronic devices.

Many manufacturers are confident that their electronic devices are not susceptible to outside electromagnetic interferences however, most of these products fail when they reach the final EMC testing stage.

This is a nightmare for most product designers and manufacturers. That’s why pre-compliance EMC testing is encouraged amongst the manufacturers and product designers.

Early Error Detection Can Speed Up The Electronic Project Lifecycle

When product deficiencies are identified early in the development process, it is easier to rectify their shortcomings. Trying to fix the shortcomings after EMC testing is expensive and time-consuming.

Pre-compliance EMC testing will let the manufacturer or designer of the electrical product focus on the areas that they have recognised as the potential reasons for concern and find the right solution to them.

The risk of design failure is relative to how long the manufacturer delays EMC testing. If you leave EMC testing to the end of the project, you will be completely reliant on the design team’s skills and competence.

This isn’t the best thing to do if you want the best final product. EMC testing and certification can help save a lot of time and money in the product development process.

Reducing The Risk Of Failing Certification

Early EMC testing can reduce the risk of failing certification. You can determine the non-compliance issues before submitting the final product for formal testing with pre-compliance EMC testing.

Pre-compliance testing will make EMC practice a less stressful experience to the manufacturer and product designers.

That’s why you should consider pre-compliance EMC testing and certification for all your electrical products.

EMC Testing Reduces Over-Engineering

Early EMC testing and certification will help reduce over-engineering and save money for the manufacturers and designers. Before the electrical product is tested, it is not known where the problems may occur.

The production team might add more countermeasures where it’s not required. More money would be unnecessarily wasted on product development areas due to overengineering.

That’s why you should conduct a pre-compliance EMC testing for all your electrical products.

Finding The Best EMC Testing Lab In Australia

Choosing the best 3rd party EMC test lab in Australia isn’t an easy task. There are many factors to look into when choosing a reputable test lab in Australia.

Your research plays an important part in this regard. It’s worth keeping the following criteria in mind when choosing the best EMC test lab in Australia:

  • Can the chosen lab do all the testing you need?
  • Will you need to find another lab to do part of the testing?
  • How close is the lab to your manufacturing facility?

Why EMC Testing Requirement

Why EMC Testing Is A Requirement

What is EMC testing and why is it required? If you are looking to launch any sort of electronic device to market, you need to understand EMC testing. Please read below as we take a deeper look into this topic.

Worldwide regulatory bodies have placed limits on the levels of electromagnetic emissions that can be generated by electronic and electrical devices.

Electromagnetic Compatibility (EMC) testing is used to ensure that electronic or electrical products do not emit large amounts of electromagnetic interference and also to ensure that devices continue to function as intended when subjected to several electromagnetic phenomena.

EMC testing and certification can be a huge burden to small as well as large manufacturers and sometimes its effectiveness can be questionable.

However, EMC rules emerged as a result of real problems experienced in the field that prompted governments and private infrastructure to accommodate and enforce these rules with electromagnetic immunity testing being mandated in some areas and for some product types.

If you are in any way involved in the design, manufacture or import of products that contain electronics, you will most definitely need to determine whether emissions and immunity tests apply to your products and exactly which standards apply.

This testing must be performed by a recognised EMC testing body to ensure that full compliance is met for testing and certification purposes.

Why EMC Testing is Necessary

Electronic devices have the potential of being vulnerable to electromagnetic fields.

With excessive numbers of these devices in the hands of the global population, the capacity for various devices to interfere with each other becomes apparent.

This has prompted regulatory authorities to state that electronic and electrical products need compliance and that they cannot be recognised as complete until all aspects related to EMC testing have been considered.

This does not just apply to commonly used products such as electronic devices, televisions, computers, and household appliance among others.

It also incorporates sensitive and high-tech products particularly sensitive to EMC influences such as aircraft, vehicles, ships, and large industrial installations.

In some countries like Canada and the United States, only emission testing is currently required (unless products fall under the scope of industry-specific standards that require immunity testing as well).

However, in Europe, both emissions and immunity testing are mandated. Countries such as Australian and New Zealand have followed the European model over the past few years.

There has been a big push from internal governments, test labs, and international standards signifying an increase in requirements for immunity testing.

Why EMC Testing is Important for Everyone

• Protection of the Electromagnetic Spectrum

There is only a certain amount of electromagnetic spectrum available for use by things like x-ray machines, radio transmissions, and microwave transmissions as well as a number of other products.

Even without transmitters, electronic devices continually emit electromagnetic radiation simply as a byproduct of switching voltages and currents inherent in electronic circuitry.

If there are no limits to the amount of unintended electronic radiation emitted by these products, our electromagnetic spectrum can be adversely affected, compromising frequency bands reserved for things like radio transmissions.

The continued explosion of wireless and non-wireless electronic products on the market has resulted in the electromagnetic spectrum being more crowded than ever.

In order to ensure that electronic devices continue to function properly in the future, the protection of the electromagnetic spectrum is essential.

• Safety Concerns

EMC performance for many industries and products can mean the difference between life and death which is why many industrial, military, medical, automotive, and aerospace products have safety-critical applications.

• Product Quality and Performance

The performance and function of electronic products can be adversely affected by internal and externally generated EMC phenomena such as in internal power supply that is too noisy.

External EMC phenomena can affect devices in a number of ways including measurement accuracy, data corruption, RF performance, and IC frying.

EMC testing can not only help you meet regulatory requirements and reduce the risk of costly non-compliance but can also help improve product performance.

This, in turn, will help to strengthen your competitive position in the industry as it is regarded as a long-term investment by many manufacturers.
