With the rapid development of railway bus vehicles, high-speed rail has become a synonym for fast and safe travel. With the improvement of the speed of high-speed rail, the requirements for locomotive materials are becoming more and more strict. The EN45545-2, as a global fire assessment requirement, has been updated with the progress of The Times. The latest version of EN45545-2 is the 2020 version, and the wire and cable EN45545-2 is tested according to the requirements of R15 or R16. Nanjing Smart has assisted many cable factories to apply for and complete the EN45545-2 test, and has rich experience in cable fire testing. Contact the hotline: +86 25-86583475.
The latest 2020 EN45545-2 divides materials into 28 categories (R 1 to R 28) depending on the end use of the material. Cables are tested per R15 and R16, where R15 is for internal cables and R16 is for external cables.

Among them, a number of bundle test based on the diameter of the cable, the selection of test methods are also different, specific can contact Nanjing Smart.
EN 45545-2:2020 R15 / R16 Test requirements
In EN45545-2 R15 / R16, according to the test results, cables can be divided into three fire risk levels (HL 1 to HL3), among which HL 3 represents the highest fire risk and the best performance of the material.
Single vertical: 50mm mark <540mm mark
Multiple bundles: combustion length 2.5m or 1.5m
Smoke density: different levels of smoke have different transmittance requirements
Toxicity: Five toxic gases were collected and analyzed to calculate the ITC value.
