Cable Entry Systems for Railroad Technology

Fire Resistance of Fire Barriers According to EN 45545-3 (E45/EI30)


The European railroad standard for fire safety EN 45545-3 regulates the fire resistance of fire barriers. The requirements and measures defined in this part of the standard aim to protect passengers and staff in trains against onboard fire incidents. icotek cable entry systems meet the classifications E45 and EI30!

Fire barriers can have different standards:


The lowest standard „E“ 

Barrier against flames, preventing fissure formation. "E45", for example, means that the specimen can withstand the test for 45 minutes.


The highest standard „EI“ 

Barrier against flames, preventing fissure formation and thermal insulation, which means that the temperature on the side facing  away from the fire must not exceed 392° F (180° K above room temperature). "EI30", for example, means that the specimen can withstand the test for 30 minutes.

Based on the standards EN 45545-3 and EN 1363-1 icotek cable entry systems have been tested on "E" and "EI" in vertical alignment using mounted IFPS fire penetration seals. All tested products have been successfully certified using only one layer of fire penetration seals. Furthermore, conventional cables instead of fire-resistant railroad cables have been used for the testing.
