1.1 本指南涵盖火灾风险评估标准的制定。 1.2 本指南旨在制定标准，提供评估对人、财产或环境有害的火灾风险的程序。 1.3 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。 1.4 本标准用于建立一种方法，将火灾场景中的潜在危害与这些场景的发生概率相结合。使用本标准评估火灾风险取决于许多因素，包括用户选择场景并使用它们表示与应用程序相关的所有场景的方式。 如果任何规范与标准中包含的规范不同，则本标准不能用于评估火灾风险。 1.5 本消防标准不能用于提供定量措施。 1.6 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 本指南旨在供制定火灾风险评估标准的人员使用。这些标准预计对制造商、建筑师、规范编写者和有管辖权的当局有用。 4.2 作为指南，本文件提供了制定火灾风险评估标准的方法的信息；未建立固定程序。数据、可用测试和模型以及科学知识的局限性可能对火灾风险评估程序和相关标准构成重大限制。 4.3 虽然本指南的重点是制定产品的火灾风险评估标准，但提出的一般概念也可应用于过程、活动、占用和建筑物。

1.1 This guide covers the development of fire-risk-assessment standards. 1.2 This guide is directed toward development of standards that will provide procedures for assessing fire risks harmful to people, property, or the environment. 1.3 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. 1.4 This standard is used to establish a means of combining the potential for harm in fire scenarios with the probabilities of occurrence of those scenarios. Assessment of fire risk using this standard depends upon many factors, including the manner in which the user selects scenarios and uses them to represent all scenarios relevant to the application. This standard cannot be used to assess fire risk if any specifications are different from those contained in the standard. 1.5 This fire standard cannot be used to provide quantitative measures. 1.6 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 for use by those undertaking the development of fire-risk-assessment standards. Such standards are expected to be useful to manufacturers, architects, specification writers, and authorities having jurisdiction. 4.2 As a guide, this document provides information on an approach to the development of a fire-risk-assessment standard; fixed procedures are not established. Limitations of data, available tests and models, and scientific knowledge can constitute significant constraints on the fire-risk-assessment procedure and associated standard. 4.3 While the focus of this guide is on developing fire-risk-assessment standards for products, the general concepts presented also can be applied to processes, activities, occupancies, and buildings.
