Fire-resistant news

Once again, these product additions are based on successful fire tests conducted at the end of last year. The fire tests followed the ISO 834-1 standard regarding temperature rise and test methods. The same temperature rise is also specified in EN 1363-1. The tests were performed together with fire-rated cables, with the circuit powered on. The fire resistance classification of the tested system components was determined based on the circuit’s functionality in a non-collapsing cable management system. A cable management system is considered damaged when it collapses or when none of the cables in the system conduct electricity.

For example, an E90 classification means that the tested system component remained functional in a non-collapsing cable management system for at least 90 minutes under ISO 834-1 standard fire conditions. You can find the standard temperature curve on the first page of the fire-resistant product brochure. It is worth noting that the temperature reaches nearly 1000°C at 90 minutes.

In horizontal installations, Meka Pro’s products have met the fire test requirements in terms of both electrical conductivity and structural integrity, with cables both secured and loose. In Meka Pro’s fire tests, the cables were not systematically secured, but only arranged to maintain order. Even in horizontal installations, loose cables did not fall from cable ladders, perforated trays, lighting support rails, or wire mesh trays, even though the cable management products deformed due to heat.

In vertical installations, Meka Pro’s products met the fire test requirements for both electrical conductivity and structural integrity only when the cables were secured.
