BS 476-4 Fire tests on building materials and structures- Part 4: Non-combustibility test for materials.
The specimen is weighted and placed into a basket. A thermocouple is inserted into the centre of the specimen and connected to the logging equipment. In addition the specimen thermocouple, there is also a thermocouple placed inside of the furnace. The specimen is lowered into the furnace (which is set at 750°C) and remains in this position for the entire 20 minute test duration.
BS 476-4 Fire Test to Building Material –Require
- Temperature rise (furnace and centre of specimen) should be ≤ 50°C
- Period of sustained flaming should be ≤ 10 seconds
