CISPR 24 Information Technology Equipment Immunity Testing
The CISPR (Comité International Special des Perturbations Radioélectriques) 24 standard defines the immunity and emission requirements for information technology equipment. Compliance with this standard is essential to ensure that electronic devices function reliably in real-world electromagnetic environments, avoiding interference from other devices.
Information technology (IT) equipment, such as computers, servers, routers, and printers, are increasingly used in various sectors including healthcare, automotive, and manufacturing. These devices must withstand electromagnetic disturbances without failure or degradation of performance to maintain system integrity. The CISPR 24 standard specifies the immunity tests that must be conducted to ensure compatibility with other electronic equipment.
The testing process involves exposing the IT equipment to a range of electromagnetic fields and assessing its response. This includes both conducted emissions, which are signals conducted along power lines or data cables, and radiated emissions, which are signals transmitted through space. The standard also covers immunity tests to ensure that the device can operate correctly in the presence of various types of interference.
Conducted emissions testing typically involves measuring the voltage on signal and power lines under specified conditions. Radiated emissions testing measures the electromagnetic energy emitted by the equipment within specific frequency bands. Immunity testing, often referred to as robustness or susceptibility tests, assesses how well the device can withstand various types of interference.
For conducted immunity testing, IT equipment is connected to a power supply and signal lines, which are then subjected to various types of noise signals. The test conditions include both continuous wave (CW) and pulse waveforms, covering a range of frequencies from 150 kHz to 80 MHz for Class A devices and up to 2 GHz for Class B devices.
During radiated immunity testing, the device is placed in an electromagnetic interference chamber that can generate various types of electromagnetic fields. The test conditions include both continuous wave (CW) and pulse waveforms, covering a range of frequencies from 150 kHz to 80 MHz for Class A devices and up to 2 GHz for Class B devices.
Testing is conducted under specific conditions to ensure that the device performs correctly in the presence of interference. The test setup includes a reference specimen that represents typical equipment performance, as well as a measurement setup that allows accurate evaluation of emissions and immunity. Testing is performed according to international standards such as CISPR 24-16, which specifies the detailed procedures for conducted and radiated emissions testing.
Compliance with the CISPR 24 standard ensures that IT equipment meets quality and safety requirements, enhancing its reliability and performance in real-world environments. This is particularly important in sectors where reliable electronic systems are critical to operations, such as healthcare and telecommunications.
The testing process requires careful preparation of the specimen, including proper grounding and shielding, to ensure accurate test results. The use of advanced instrumentation, such as spectrum analyzers and signal generators, allows for precise measurement of emissions and immunity performance. Reporting is conducted according to international standards, providing clear documentation of test results and compliance status.
Understanding the CISPR 24 standard and its testing procedures is crucial for manufacturers and quality managers to ensure that their IT equipment meets regulatory requirements and performs reliably in real-world conditions. The testing process not only ensures compliance but also enhances the overall reliability and performance of electronic devices, contributing to safer and more efficient systems.
