CISPR 25 Testing Services

CISPR 25 Testing Services To Ensure Your Components Meet International (EMC) Standards

CISPR 25 is an international standard developed by the International Special Committee on Radio Interference (CISPR), a subsidiary of the International Electrotechnical Commission (IEC). It specifies limits and procedures for measuring radio disturbances in vehicles and their components.   

Compliance with CISPR 25 is essential for ensuring the proper functioning of vehicle systems, such as radios, navigation systems, and safety features. It also helps to prevent interference with external communication systems like cellular networks and radio broadcasts

Our CISPR 25 testing services include a range of tests to ensure compliance with EMC requirements, preventing unwanted emissions and disturbances that can affect the performance of vehicle electronics.

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

Radiated emissions are electromagnetic signals unintentionally emitted by electronic components. These emissions can interfere with nearby devices and systems. At H.B. Compliance, we perform radiated emissions testing across a wide frequency range of 0.15MHz to 5000MHz, measuring both narrowband and broadband emissions to identify potential issues and help you meet industry limits.

  • CISPR 25 Section 6.4 – RF Emissions Antenna Measurement 

Testing for RF emissions ensures that components do not emit harmful radio frequencies that could interfere with vehicle communications or other systems. We measure RF emissions between 30MHz and 1GHz, assessing the effectiveness of antenna performance and minimizing risks of interference.

  • CISPR 25 §6.2 – Conducted Emissions Voltage Method (DC Power) 

Conducted emissions testing measures disturbances on the DC power lines of components. We evaluate emissions between 150kHz and 108MHz to ensure that components do not send harmful electromagnetic interference through their power connections.

  • CISPR 25 §6.3 – Conducted Emissions Current Probe Method 

Our current probe method for conducted emissions testing assesses the disturbance current on the full wiring harness of the component, covering frequencies from 150kHz to 245MHz. At HBCS we deliver the best services for Automotive Component EMC Testing to ensure that your components meet CISPR 25 requirements. (Please note, we test individual components, not entire vehicles.)
