Why EMC is Crucial in Information Technology
In today’s landscape of electronics and telecommunications, IT equipment operates in environments with high electromagnetic density: Wi-Fi networks, mobile devices, industrial systems, smart home automation. In this context, Electromagnetic Compatibility (EMC) becomes a critical aspect for the functionality, safety, and regulatory compliance of products.
An IT device that complies with EMC regulations not only ensures that it does not cause harmful interference to other electronic systems, but also that it functions correctly when exposed to external disturbances. For manufacturers, compliance is mandatory for access to many markets, especially those governed by harmonized international standards.
CISPR 32: The Reference Standard for Multimedia Equipment Emissions
CISPR 32 is the international reference standard for assessing the electromagnetic emissions of multimedia equipment, which includes both Information Technology (IT) and Audio/Video (AV) devices. It is a harmonized standard recognized in many jurisdictions, including:
Europe (EN 55032, CE marking)
United States (FCC Part 15, with technical alignment)
Regions adopting IEC standards (via CB certification)
Key Technical Content of the Standard:
Conducted Emissions (150 kHz – 30 MHz)
Measures interference transmitted through power and signal cables. Tests are performed on AC/DC lines in shielded environments using LISNs (Line Impedance Stabilization Networks) and spectrum analyzers.Radiated Emissions (30 MHz – 6 GHz)
Evaluates electromagnetic waves radiated into the environment, which may impact the device’s electromagnetic compatibility. Measurements are carried out in semi-anechoic chambers, typically at 3 or 10 meters, using log-periodic and biconical antennas.
Why CISPR 32?
Replaces and harmonizes CISPR 22 (IT) and CISPR 13 (AV), making it suitable for modern, hybrid devices
Applicable to various usage environments: domestic, commercial, and light industrial
Compatible with the modular approach to CE compliance, when used together with CISPR 35 for immunity requirements
CB Certification: The Global Passport for IT Equipment
The CB Scheme (IECEE Certification Body Scheme) is a multilateral system that enables mutual recognition of test reports between accredited Certification Bodies (NCBs) and Testing Laboratories (CBTLs). This is particularly beneficial for international manufacturers and distributors.
Key Benefits of CB Certification:
One test, multiple markets: Avoids duplicated testing in each country, reducing time and costs
Recognized in over 50 countries, including Europe, the U.S., Canada, Japan, China, Korea, and Australia
Harmonized approach: Tests are carried out according to international IEC standards, including IEC 61000-x-x and CISPR 32
A CB Test Report issued by an accredited CBTL laboratory like ours serves as a launchpad for obtaining national certifications or conformity markings quickly and efficiently.
The Added Value of an Accredited and CBTL Laboratory
Relying on an accredited laboratory for EMC testing and one that is recognized as a CBTL (Certified Body Testing Laboratory) ensures superior guarantees in terms of quality, traceability, and international acceptance.
