CISPR 25 is an international standard that sets out the requirements for radio disturbance characteristics for the protection of receivers in vehicles. The standard is developed and published by the International Electrotechnical Commission (IEC) and is widely adopted across the globe.

Legal and Regulatory Framework

The legal and regulatory framework surrounding CISPR 25 testing is governed by a range of international and national standards, including:

These standards provide a framework for testing and certification, ensuring that vehicles meet specific requirements for radio disturbance characteristics.

International and National Standards

CISPR 25 is an international standard developed by the IEC. It is adopted by many countries as a national standard. In the European Union (EU), CISPR 25 is implemented through Directive 2014/30/EU on electromagnetic compatibility, which requires all new vehicles to comply with the standard.

Standard Development Organizations

The IEC is responsible for developing and publishing CISPR 25. The IEC is a non-profit organization that brings together experts from around the world to develop standards for the benefit of society.

How Standards Evolve and Get Updated

Standards evolve and get updated in response to new technologies, changing regulatory requirements, or other factors. This ensures that standards remain relevant and effective over time.
