Automotive EMC Testing for Components and Sub-Assemblies

ISO 11452 is a series of international standards that provide guidelines and requirements for Electromagnetic Compatibility (EMC) testing of automotive components and sub-assemblies. These standards are essential to ensure the safe, reliable, and efficient operation of electronic systems in vehicles.

Compliance with ISO 11452 helps to prevent interference between electronic systems within the vehicle, reducing the risk of malfunctions and ensuring the overall safety of the vehicle. We offer testing services based on ISO 11452, which covers a variety of critical tests designed to assess both the emissions and immunity of automotive components.

  • CISPR 25 § 6.3 – Conducted Emissions Voltage Method (DC Power) 

The Conducted Emissions Voltage Method assesses the amount of unwanted voltage generated by automotive components when powered. This test covers frequencies from 0.15 to 108MHz. At H.B. Compliance, we utilize advanced testing equipment to measure emissions, ensuring they remain within the prescribed limits to prevent interference with other vehicle systems.

  • CISPR 25 § 6.4 – Conducted Emissions Current Method (DC Power) 

Our testing also includes the Conducted Emissions Current Method, which evaluates the current disturbances along power lines. This method focuses on frequencies from 0.15 to 245MHz and is essential for ensuring that your components do not disrupt the electrical systems of the vehicle. We perform this testing to verify compliance with industry standards and ensure optimal performance.

  • CISPR 25 § 6.5 – Radiated Emissions (Narrow/Broadband) 

Radiated emissions testing is crucial for evaluating how much electromagnetic radiation a component emits into the environment. Our services cover a broad frequency range from 0.15MHz to 5925MHz, assessing both narrowband and broadband emissions. This ensures that your components do not interfere with sensitive automotive electronics or external devices.

  • ISO 11452-4 – Conducted Immunity (BCI) 

Bulk Current Injection (BCI) testing evaluates the immunity of components against conducted disturbances on their power and signal lines. We perform these tests in the frequency range of 0.1MHz to 400MHz to ensure that your components can withstand electromagnetic interference and maintain proper functionality.

  • ISO 11452-2 – Radiated Immunity 

Our Radiated Immunity testing assesses a component’s resilience to external electromagnetic fields in the range of 80MHz to 2GHz. We simulate real-world scenarios to ensure that your components can operate effectively in environments with significant electromagnetic interference.

  • ISO 10605 – Electrostatic Discharge (Powered and Un-powered)

Electrostatic Discharge (ESD) testing is vital for protecting sensitive components from sudden voltage spikes caused by static electricity. We conduct tests under both powered and un-powered conditions to ensure that your components can withstand these disturbances.

Overall, ISO 11452 is a crucial standard for ensuring the electromagnetic compatibility of automotive components and sub-assemblies. By following these standards, manufacturers can enhance the reliability, safety, and performance of their vehicles, ultimately benefiting both consumers and the automotive industry as a whole.
