Best results in tests in accordance with EN 45545-2 (components)

The sealing inserts for^{the Progress®} cable gland are made from a special TPE and are certified to the most demanding Hazard Level 3 standard. The required values for Hazard Level 3 were significantly exceeded in both outdoor and indoor environments.

Exceeds the requirements of EN 45545-3!

EN 45545-3 defines the fire resistance requirements for fire-resistant penetrations. The aim of EN 45545-3 is to limit the spread of fire through material requirements. When cables are routed through fire-resistant penetrations, these requirements also apply to cable glands.

To determine whether the required fire resistance is achieved, the components are tested in a test furnace with regard to the criteria of room separation, thermal insulation and radiant heat emission.

AGRO Progress® metal cable glands far exceed the requirements of EN 45545-3 and achieve the very high fire resistance class E30. This means that the sealing inserts remain watertight for at least 30 minutes and prevent the spread of flames to the side facing away from the fire. No gaps form. From a fire safety perspective, they can be used without hesitation in all rail vehicles.
