Carpet Flammability Tester
Carpet flammability tester is designed for assessing the effects of a small source of ignition on floor coverings. The test chamber is manufactured from non-combustible heat resistant board with a counter weighted sliding panel for easy access. The transparency window on top of the chamber allows the users to view the specimen during the test.
Carpet Flammability Tester can be used for either the hot metal nut test (BS 4790) or the methenamine tablet test (ISO 6925 and BS 6307).
Hot Metal Nut Test: The stainless steel nut is heated to a temperature of 900°C in a muffle furnace. Place the specimen in the bottom of the test chamber and the clamping rig is placed onto the sample using crucible tongs supplied. The heated nut is put in the centre of the clamping rig. Remove the nut after 30 seconds. A measurement of spreading of the ignition on the sample is made to evaluate the flammability of the carpet.
Methenamine Tablet Test: It is recommended that the test chamber is placed in a laboratory fume hood. Place the conditioned specimen on the removable base inside the test chamber and the metal plate with a circular cut-out is placed on the specimen. The tablet is placed at the center of the specimen and ignited. After the flame has extinguished, measurements are taken to assess the effect on the carpet.
