ASTM E 1474：Standard Test Method for Determining the Heat Release Rate of Upholstered Furniture and Mattress Components or Composites Using a Bench Scale Oxygen Consumption 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 for upholstery and mattress product designs and product development.
Heat release measurements provide useful information for product development by yielding a quantitative measure of specific changes in fire performance caused by component and composite modifications. Heat release data from this test method will not be predictive of product behavior if the product does not spread flame over its surface under the fire exposure conditions of interest.Test Limitations—The test data are invalid if either of the following conditions occur: (1) explosive spalling; or (2) the specimen swells sufficiently prior to ignition to touch the spark plug, or the specimen swells up to the plane of the heater base during combustion.
