To prevent the spread of smoke within a building, the Dutch Besluit bouwwerken leefomgeving (Bbl) sets requirements for smoke resistance. These requirements are expressed in classes Ra and R200. All construction elements present in such a partition must meet class Sa or S200 respectively, representing smoke leakage at ambient temperature (Sa) or at elevated temperature (S200).
The smoke leakage of a construction element, such as a door assembly, is determined by performing a test using the so-called ‘smoke cabinet’. This is an airtight test cabinet that can be pressurised. For the S200 test, the cabinet is also electrically heated to 200 °C. A positive pressure is applied to one side of the test specimen, and the leakage rate is measured at three pressure differentials (10, 25 and 50 Pa).
We perform smoke leakage tests for the following construction components:
Extension of the field of application for doors, windows and operable parts is possible by drawing up an Extended Application (EXAP) report in accordance with EN 15269-20. The test results for doors, windows and operable parts are classified in accordance with EN 13501-2. For questions, please contact one of our project managers.
