Certified safety
Tests according to the RWS fire curve
The RWS fi re curve simulates extremely high temperatures of up to 1350 °C over a fire duration of up to 240 minutes. Products such as our ZZ® 535 Fire Protection Joint Seal and ZZ® 345 Fire Protection Silicone have been successfully tested according to this curve. This makes them ideally suited for safety-critical applications in tunnel construction.
Tunnel atmosphere and durability (type X)
Tunnels pose special challenges due to high humidity and temperature fluctuations. Our ZZ® 535 Fire Protection Joint Seal and ZZ® 345 Fire Protection Silicone have successfully passed tests for durability and weather resistance. With their Type X classifi cation, they are reliably suitable for use in tunnels.
European Technical Assessments (ETA)
Our European products have been extensively tested – including tests for weather resistance and durability – and have a European Technical Assessment (ETA). This allows them to be used across borders within Europe and ensures maximum comparability and safety thanks to harmonised testing procedures.
General building approvals (aBG)
All our fi re protection systems used in Germany have a general building approval (aBG) from the German Institute for Building Technology (DIBt). This ensures that our solutions are recognised by building authorities and guarantee the highest level of safety.
