RESISTANCE TO FIRE TESTING is the term for testing of systems designed to contain or resist the passage of fire for a specified length of time. The sample fire door, block wall, glass partition, fire / smoke damper or similar system is installed in a frame which is then placed on the vertical open side of the fire testing furnace.
The temperature in the furnace is raised by the computer control system to follow a prescribed time/temperature curve, and various checks for failure criteria are conducted to determine the time rating of the specimen.
Through our partner, Tom Bell Wright, we now have four furnaces, one industry standard 3m x 3m vertical furnace, a 4m x 5m vertical furnace, a 4m x 5m horizontal furnace and a 1.8m cube furnace for ‘indicative’ (product development) tests.
