EMC Testing for Electrical Components

One of the key standards we test is ENS0310, which governs the EMC testing methods for electrical components used in trucks. This standard is critical for ensuring that the components operate efficiently, even in challenging electromagnetic environments, and that they do not cause interference with other electronic systems in the vehicle.

Below are the key sections of the ENS0310 standard that we cover in our testing services:

• Section 14.7.3.7-14.7.3.8 – ISO 13766-1 Electrostatic Discharge (Handling/Packaging/Repair) Powered/Unpowered

Electrostatic discharge (ESD) is a significant concern when it comes to handling, packaging, or repairing electrical components. ESD can cause major damage to sensitive electronics, affecting their functionality or rendering them inoperable. We simulate real-world scenarios, testing both powered and unpowered conditions, ensuring that the components are robust enough to withstand ESD in various handling and operational environments.

• Section 14.7.4.2 – ISO 11452-2 Radiated Immunity 

Radiated immunity testing is critical to ensure that your components can resist interference from external electromagnetic fields. This is especially important in truck environments where powerful transmitters and other electronic systems can emit electromagnetic radiation that might interfere with the functioning of the components.

Our testing under ISO 11452-2 focuses on frequencies between 200MHz and 6GHz, simulating various real-world electromagnetic environments. We expose the components to continuous wave (CW), amplitude modulation (AM), and pulse modulation (PM) fields, ensuring they can maintain functionality without being affected by radiated electromagnetic disturbances.

• Section 14.7.4.3 – ISO 11452-2 Bulk Current Injection 

Bulk Current Injection (BCI) is an essential part of conducted immunity testing. This test evaluates the resistance of components to electromagnetic interference conducted along their wiring. The test involves injecting currents directly into the cables of the component to simulate the effects of electromagnetic disturbances transmitted through the vehicle’s wiring.

We deliver ISO 11452-2 BCI tests between 0.1MHz and 400MHz, with current injections applied at various distances, including 150mm, 450mm, and 750mm. Our testing ensures that your components can withstand conducted electromagnetic disturbances while maintaining proper functionality.

• ISO 11452-9 – Portable Transmitter Radiated Immunity

Portable transmitters, such as radios and mobile devices, are common sources of radiated electromagnetic interference within vehicles. Testing for portable transmitter radiated immunity ensures that components can resist the interference caused by these devices, which can operate across a wide range of frequencies.

At H.B. Compliance, we conduct ISO 11452-9 tests on components to assess their immunity to electromagnetic fields from portable transmitters operating in the 146MHz to 3.8GHz frequency range. This testing for components used in trucks ensures that they remain unaffected by high-frequency transmitters in real-world conditions.
