Why Are Automotive EMC Standards Important?


Automotive EMC testing checks the electromagnetic compatibility for the vehicle as well as all the components. It is crucial to monitor every aspect of the vehicle and determine whether any are generating electromagnetic interference (EMI). The typical car dashboard is now filled with active components that must operate without causing disruption.

Car manufacturers understand that modern vehicles can have as many as 75 different electronic modules. These are crucial elements that determine whether a vehicle is safe on the road relating to everything from braking to steering and tailpipe emissions. As such, without automotive EMI testing, it’s possible that any one of these different modules could potentially fail in your product.

EMC testing and compliance is now a crucial element for not just safety but the performance of a vehicle and ultimately the revenue stream of an automobile manufacturer or part supplier.

ISO, CISPR, and SAE mainly develop automotive EMC standards. These standards are maintained at an international level. Vehicles that market worldwide will typically reference both CISPR and ISO standards.

Frequently Asked Questions

EMC Testing is a long-term investment. It is mandatory for certain products, and successful results allow manufacturers and importers to sell their product in multiple markets. The testing also allows manufacturers to improve the quality of their equipment and succeed in a competitive market.

Radiated immunity tests measure the susceptibility of your device. Emissions from other devices in the surrounding area could affect your device. Immunity ensures that your device can withstand the emissions of surrounding gadgets. Otherwise, the interference can lead to a host of problems down the road.

Choosing the right EMC testing lab can save you a lot of hassle down the line. It can help you get your products to market quicker and ensures that all relevant compliance standards have been met. Remember, the key points to take away when choosing an EMC test lab are:

You should opt for an accredited service provider that can provide you with the relevant technical documentation and certifications
They should offer the right level of technical expertise and experience
They need to provide the right kinds of test and services pertinent to your product(s)
They should have the required equipment and facilities available – so check what these are
You want a lab that is conveniently located and offers a turnaround time that fits with your timetable
Comply with EMC directive standards

EMC testing is essential in ensuring that devices in electromagnetic environments work. Furthermore, EMC compliance certifications are mandatory in the majority of markets around the world, including the US, Europe, China, Australia, and New Zealand.
