CISPR 25 Automotive Component Test Facility

Specifically designed for automotive testing to meet the requirements of component testing to EN55025 / CISPR 25.


Global EMC’s CISPR 25 automotive test facility has been specifically designed for automotive testing to meet the requirements of component testing to EN55025 / CISPR 25 and ISO 11452-1. The chamber is also compliant for immunity component tests to ISO 11452-2. The low height of the chamber means it will easily fit within most buildings. The chamber is constructed using a self-standing steel structure and modular steel shield. This is complimented with high performance pyramidal Hybrid Absorbers and ferrite tiles to walls and ceiling as required to make a semi anechoic chamber.


Testing facility for performing compliant radiated emissions with EN55025/CISPR 25 component and immunity testing to ISO 11452-2 component. This chamber is used for testing electronic sub-assemblies of receivers mounted on-board vehicles.
