文件规定: -用于确定在给定房间内的防火屏障上要考虑的热效应的指南； -基于标准测试表征确定防火屏障整体性能的指南； -评估是否需要进行额外测试以验证溶液耐用性的指南。 详细介绍了适用标准、数值工具确认和验证（V&V）的要求以及耐火实验室的预期资格。 讨论了该方法的适用性和范围的局限性。 本文件的目的和理由是描述一种用于验证防火屏障效率的新方法，该方法最初基于标准化的耐火性测试。 这项工作的意义在于，目前的方法将通过结合标准化测试数据为危险分析提供更多的现实性来提高安全水平。它完成了证明性能合理性所需的标准ISO防火等级。 与ISO防火等级给出的分类相比，这种方法最相关的好处是确定屏障在持续时间延长的火灾中的整体性能。

The document provides: — guidelines for determining the thermal effects to consider on fire barriers inside a given room; — guidelines for determining the global performance of the fire barriers based on standard test characterization; — guidelines for assessing the need for additional tests to verify the robustness of the solution. Requirements of applicable standards, numerical tools validation and verification (V&V), and the expected qualification of fire resistance laboratories are detailed. The limitations of the method's applicability and scope are discussed. The purpose and justification of this document is to describe a new methodology for the verification of the efficiency of fire barriers, which is initially based on a standardized fire resistance test. The significance of this work relates to the fact that the present methodology will enhance the level of safety by providing more realism to hazards analysis in combination with standardized test data. It completes the standard ISO-fire rating required for justifying the performance. The most relevant benefit of this method concerns the determination of the global performance of a barrier in a fire of extended duration compared to the classification given by the ISO-fire rating.
