ISO 17492:2003规定了一种测试方法，用于测量水平安装的阻燃纺织材料在接触对流能和辐射能组合时的传热。当所有结构或子组件均由阻燃材料制成时，本试验方法可用于单层或多层结构中使用的任何类型的板材。它不适用于不耐火的材料。本试验方法不适用于评估暴露于任何其他类型热能源（如仅辐射热或仅火焰接触）的材料。评估热量时使用ISO 6942-仅因辐射热而通过材料进行传热，在评估仅因火焰接触而通过材料进行传热时，使用ISO 9151。ISO 17492:2003应用于测量和描述受控实验室条件下材料、产品或组件对对流和辐射能的响应特性，而不应用于描述或评估实际火灾条件下材料、产品或组件的火灾危险或火灾风险。然而，本试验方法的结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。

ISO 17492:2003 specifies a test method for measuring the heat transfer of horizontally mounted flame-resistant textile materials when exposed to a combination of convective and radiant energy.This test method can be used for any type of sheet material used either as a single layer or in a multilayer construction when all structures or sub-assemblies are made of flame-resistant materials. It is not intended to be used on materials that are not flame resistant.This test method is not intended for evaluating materials exposed to any other type of thermal-energy sources, such as radiant heat only or flame contact only. Use ISO 6942 when evaluating heat-transfer through materials due to radiant heat only and use ISO 9151 when evaluating heat-transfer through materials due to flame contact only.ISO 17492:2003 should be used to measure and describe the properties of materials, products or assemblies in response to both convective and radiant energy under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, the results of this test method may be used as elements of a fire-risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.
