Rail Transit EN 50155 Electromagnetic Compatibility (EMC) Test

en 50155 testing is a critical step in ensuring the quality of electronic equipment used in rail transit. Today, let us take an in-depth look at the rail transit EN 50155 testing items.

Do All Test Items Need to Be Performed for EN 50155 Rail Transit Product Certification?

The mandatory railway test items specified in the standard must be performed, while other items can be negotiated and tested based on actual requirements.

How Long Does the EN 50155 Certification Cycle Take for Rail Transit Products?

Because the EN 50155 standard requires a large number of test items and extensive technical documentation to be submitted for review, the certification cycle is relatively long. Advance planning is recommended if certification is needed; under normal circumstances, it takes approximately 15 to 30 days.
