ASTM E 1740:Standard Test Method for Determining the Heat Release Rate and Other Fire-Test-Response Characteristics of Wallcovering Composites Using a Cone Calorimeter
Abstract 摘要
This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus.Quantitative heat release measurements provide information that can be used to compare wall or ceiling coverings and constructions and for input to fire models.
Heat release measurements provide useful information for product development by giving a quantitative measure of specific changes in fire performance caused by component and composite modifications.Heat release data obtained by this test method will be inappropriate if the product will not spread flame over its surface under the fire exposure conditions of interest.Variations in substrates, mounting methods, and adhesives used to laminate composite products will potentially affect the test responses. These variables must be controlled during any comparative experiments.
