IoEN ISO 9239-1 Reaction to fire tests for floorings

The fire test EN ISO 9239-1 evaluates the ability of floorings to withstand flames and radiant heat. The product's flame spread, smoke generation and the lowest radiant heat to sustain burning are measured in the method (CHF). The method is mainly used to classify floor coverings according to the European system for Euroclass EN 13501-1. The test is used to classify floorings for classes A2fl, Bfl, Cfl and Dfl. The test specimen is placed in a horizontal position below a gas-fired radiant panel inclined at 30° where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen. Following ignition, any flame front which develops is noted and a record is made of the progression of the flame front horizontally along the length of the specimen in terms of the time it takes to spread to defined distances. Smoke production during the test is recorded as light transmission in the exhaust stack. One specimen is tested in one direction (e.g. production direction) and one specimen is in the direction perpendicular to the first specimen. The test that yields the worst results are repeated twice in that direction.

Suitable sample matrices
Construction products (floorings)
Minimum sample amount
Cut 3-4 (1 050 ± 5) mm ´ (230 ± 5) mm, three in one direction (e.g. production direction) and three in a direction perpendicular to the first direction. If the thickness of the specimen is more than 19 mm, the length may be reduced to (1025 ± 5) mm
