1.1 本指南描述了数学火灾增长模型输入所需的数据。 1.2 提供了如何获得数据的指南。 1.3 本指南的重点是固体材料的点火、热解和火焰传播模型。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本消防标准不能用于提供定量措施。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南主要面向数学火灾增长模型的用户和开发人员。它对进行火灾测试的人员也很有用，使他们了解小型火灾的一些重要应用和用途- 比例尺火灾测试结果。因此，本指南有助于提高火灾增长模型计算的准确性，这在很大程度上取决于输入数据的质量。 4.2 本指南的重点是固体材料的点火、热解和火焰传播模型。

1.1 This guide describes data required as input for mathematical fire growth models. 1.2 Guidelines are presented on how the data can be obtained. 1.3 The emphasis in this guide is on ignition, pyrolysis and flame spread models for solid materials. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This fire standard cannot be used to provide quantitative measures. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide is intended primarily for users and developers of mathematical fire growth models. It is also useful for people conducting fire tests, making them aware of some important applications and uses for small-scale fire test results. The guide thus contributes to increased accuracy in fire growth model calculations, which depend greatly on the quality of the input data. 4.2 The emphasis of this guide is on ignition, pyrolysis and flame spread models for solid materials.
