ISO 9239-1:2002 Constructions Material Radiation Heat Flux Testing Machine for Floor Coverings

Scope of application:

Suitable for testing with a small flame igniting a floor covering material that is placed horizontally and exposed to an inclined thermal radiation field.

Suitable for all kinds of flooring materials. Such as: textile carpets, cork, wood plastic flooring and floor spraying materials. The device may reflect the burning properties of the flooring material including the substrate used, backing material, underlay material, or flooring material

Changes in the aspects may affect the test results, which are used to test and describe the combustion characteristics of the paving materials in response to pyrophoric thermal reaction under laboratory controlled conditions.
