Automotive Electronics CE Certification EN 50498 Test

Introduction to the EN 50498 Standard

Within the complex framework of automotive electronic product certification, the EN 50498standard holds a crucial position. With the rapid development of automotive intelligence, a wide range of in-vehicle electronic devices have emerged — from common car chargers and refrigerators to sophisticated in-car audio-visual entertainment systems. While these devices bring convenience, they also introduce various electromagnetic compatibility (EMC)challenges.

EN 50498is a European standard specifically formulated for the EMC requirements of in-vehicle electronic devices. As a harmonized European EN standard, it defines the CE self-declaration conformity process.

In simple terms, manufacturers whose products comply with EN 50498 can self-declare conformityto relevant EU directives and affix the ce mark, allowing the product to be sold in the EU market.

The purpose of this standard is to ensure that automotive electronic devices operate normally within the complex electromagnetic environment of a vehicle, while not causing harmful electromagnetic interference (EMI) to other onboard systems.

Scope of EN 50498

The EN 50498 standard primarily applies to non-critical in-vehicle electronic devicesthat could affect driving safety. Common examples include:

- Car Chargers

Devices powered through the cigarette lighter socket must ensure they do not interfere with other vehicle electronics during charging.

- Car Refrigerators

Whether semiconductor-based or compressor-based, these must comply with the standard to avoid electromagnetic interference that could affect cooling performance or other onboard electronics.

- Car Entertainment Systems

Devices such as DVD players or audio systems must ensure that during playback, they do not interfere with navigation, onboard computers, or other systems.

- Wireless Communication Devices

Products equipped with Bluetooth, Wi-Fi, or similar wireless functions must comply with both the Radio Equipment Directive (RED)and the EMC requirements of EN 50498.

This standard applies to non-critical automotive equipment as defined in Annex I of Directive 2004/104/EC.

The test items include broadband/narrowband radiated disturbances, conducted transient emissions, and immunity tests.

EN 50498 Test Items

1. Broadband Radiated Disturbances

Tests the product’s electromagnetic radiation within the frequency range of 30 MHz to 1000 MHz, with the device operating in its typical mode and at maximum emission levels.

2. Narrowband Radiated Disturbances

Focuses on specific frequency bands of electromagnetic radiation; the testing method is similar to broadband testing.

3. Conducted Transient Emission Test

Measures transient interference conducted through power lines or similar paths — for example, voltage fluctuations during charging.

4. Conducted Transient Immunity Test

Based on ISO 7637-2, this test evaluates the product’s resistance to transient disturbances transmitted through power lines.

EN 50498 CE certification Process (JJR)

1. Complete the Test Application Form

Provide detailed information about the product and testing requirements.

2. Send Samples to the JJR Laboratory

Ship the necessary samples securely for evaluation.

3. Product Testing & Rectification

The laboratory conducts the tests. If non-compliance is found, the company will be notified to modify and resubmit the samples.

4. Issuance of Test Report

Upon passing all tests, the JJR laboratory issues an official EN 50498 test report.
