CISPR 24 Immunity Requirements for Information Technology Equipment

CISPR 24 Immunity Requirements for Information Technology Equipment: A Comprehensive Guide to Laboratory Testing Services

Standard-Related Information

The CISPR (International Special Committee on Radio Interference) 24 standard is a widely recognized international standard that outlines the immunity requirements for information technology equipment (ITE) against electromagnetic interference (EMI). The standard is published by the International Electrotechnical Commission (IEC) and is harmonized with other international standards, such as ISO/IEC 17025 and ASTM E1838.

Legal and Regulatory Framework

The CISPR 24 standard is a critical requirement for ITE manufacturers and users to comply with in many countries. The standard is often referenced in national regulations, such as those found in the European Unions Electromagnetic Compatibility (EMC) Directive (2014/30/EU), which mandates that all electrical and electronic equipment must be designed and constructed to prevent electromagnetic interference.

International and National Standards

The CISPR 24 standard is widely adopted across the globe and is an essential requirement for many industries, including:

Some of the key international standards related to CISPR 24 include:

Standard Development Organizations

The CISPR committee is responsible for developing and maintaining the CISPR standards, including CISPR 24. The IEC is the primary standard development organization (SDO) for electromagnetic compatibility (EMC) standards.

How Standards Evolve and Get Updated

Standards are periodically reviewed and updated to reflect changes in technology, regulations, and industry practices. The SDOs work with experts from around the world to develop new editions of standards that address emerging issues and technologies.

Standard Numbers and Scope

Test Conditions and Methodology

The CISPR 24 test is a radiated immunity test, which involves exposing the ITE to electromagnetic radiation at specific frequencies. The test is conducted in a controlled environment with precise temperature and humidity conditions.

Step-by-Step Explanation of How the Test is Conducted

Here is a step-by-step explanation of how the CISPR 24 test is conducted:

1. Sample preparation: The ITE is prepared for testing by ensuring that it is properly connected to the testing equipment.

2. Testing environment setup: The testing environment, including temperature and humidity control, is set up according to the standard requirements.

3. Electromagnetic radiation generation: Electromagnetic radiation is generated at specific frequencies using a transducer or antenna.

4. Radiated immunity test: The ITE is exposed to electromagnetic radiation at specific frequencies for a specified duration.

5. Data collection and analysis: Test data is collected and analyzed using specialized software.

Test Equipment and Calibration

Eurolab uses state-of-the-art testing equipment that is calibrated regularly according to international standards.

Reporting and Certification
