Proven fireproof conduit fastenings 14 October 2021

Conduit installations must retain their load-bearing capacity for a sufficient length of time in the event of fire. fischer has therefore helped develop the European Assessment Document (EAD) 280016-00-0602 for pipe support systems and optimised it for fire protection, which is serving as the basis for the European Technical Assessment (ETA) for fischer products.

Significant deformation can occur on rail constructions when exposed to fire. Severe consequences include the system failure of the suspended ceilings located below, which exposes escape and rescue routes to smoke and fire. Conduit installations in escape and rescue routes must therefore be designed to withstand fires, which can save lives. fischer contributed to modifying the European Assessment Document (EAD) 280016-00-0602 published by the German Institute for Structural Engineering (DIBt) and optimised the document for fire protection purposes.

This now allows European Technical Assessments (ETAs) for approved conduit fastening products to be created with CE Marking, while the fire resistance of installations is assessed and proven according to up to date technical knowledge. During this process, each construction product of a fischer pipe support system is tested and assessed by a specially accredited institute before being transferred into an ETA. As fischer has already carried out tests similar to EAD requirements in recent years, a lot of data from past tests served as the basis for the design.

The fischer FUS channels have already been assessed based on the EAD 280016-00-0602 (ETA – 21/0140). The ETAs enable specialist application designs to be carried out, allowing channels to be simulated with any number of pipe support system configurations for the event of fire. Changes to the planned kits can be carried out quickly, flexibly and affordably at any time. All products used will feature CE Marking in future, which makes the overall configuration an approved application, providing added flexibility.

Additional installation system products from fischer Group of Companies will gradually follow on from the FUS channels, as their safety under fire exposure is proven in accordance with the ETA.
