ISO 6941 Textile Fabrics Burning Behavior Flame Spread Properities Testing Chamber
Application:
The textile fabrics burning behavior tester is designed according to ISO 6941:2003 “Measurement of flame spread properties of vertically oriented specimens”. It is used to access the properties of textile fabrics in response to flame contract under controlled conditions, suitable for vertical burning performance testing of all kinds of single component or multi-component (coating, quilting, multi-layer, sandwich products and similar combinations) textile fabrics and industrial products.
Principle:
A defined flame from a specified burner is applied for 10s to the surface or the bottom edge of textile specimens that are vertically oriented. The flame spread times in seconds for the flame front to travel between marker threads positioned adjacent to the surface of the test specimen and located at three distances from the igniting flame, are recorded.
