The Electromagnetic Compatibility Laboratory of Beijing Yizong Institute provides a pulse magnetic field immunity test, which is an electromagnetic compatibility testing method. It evaluates the anti-interference capability of electronic devices to ensure they remain unaffected by external electromagnetic interference in real-world applications.

The primary test subjects for pulse magnetic field immunity testing are electronic devices, including computers, communication equipment, industrial control devices, and more. During the test, representative electronic devices are selected for pulse magnetic field immunity evaluation.

Basic standards for pulse magnetic field immunity: GB/T 17626.9-2011, IEC 61000-4-9:2001.

Pulse magnetic field testing standards for the rail transit industry:

Emission and immunity of signaling and communication equipment: GB/T 24338.5-2018, IEC 62236-4:2008.

Railway signaling power system equipment: TB/T 1528.2-2018.

Railway station computer interlocking test specifications: TB/T 3537-2018.

Technical requirements for railway station computer interlocking: TB/T 3027-2015.

Environmental conditions for rail transit equipment—Signaling and communication equipment: EN 50125-3:2003.

Power industry standards: Basic testing methods for relay protection and security automation equipment: GB/T 7261-2016, DL/T 478-2013.

In today's technology-driven era, where electronic devices are ubiquitous, electromagnetic compatibility (EMC) has become an indispensable aspect of product design. This is especially true for rail transit equipment. To ensure the normal operation of trains, track signals, and other related devices, the Beijing Electromagnetic Compatibility Laboratory has conducted in-depth research on pulse magnetic field immunity for rail transit equipment and achieved significant results.

As a CNAS-accredited institution, the Beijing Electromagnetic Compatibility Laboratory possesses advanced testing equipment and a professional testing team. In accordance with the GB/T 17626.9-2011 standard, we have conducted comprehensive and thorough testing on the pulse magnetic field immunity of rail transit equipment. Through this testing, we can accurately assess the device's ability to resist pulse magnetic field interference during actual operation, thereby ensuring its stability and reliability.

Moreover, we hold CMA-accredited reporting qualifications and are recognized as a third-party testing institution. This means our test results carry high authority and credibility, providing reliable assurance for the safety of rail transit equipment. Additionally, we offer third-party testing reports to help clients better understand their equipment's performance and potential issues.

In the rail transit sector, the emission and immunity of signaling and communication equipment are of utmost importance. In accordance with standards such as GB/T 24338.5-2018, IEC 62236-4:2008, TB/T 1528.2-2018, TB/T 3537-2018, and TB/T 3027-2015, we conduct comprehensive testing on rail transit signaling and communication equipment. These standards cover aspects such as equipment emission, immunity, power supply panel testing methods, computer interlocking test specifications, and technical requirements.

Our pulse magnetic field immunity testing is not limited to the rail transit industry; it can also be applied to other sectors, such as railway stations and subways.
