1.1 本规程描述了一系列已使用的点火源，这些点火源可能适用于评估材料、产品或组件点火引起的火灾试验响应特性。 1.2 本规程未确定所述的哪些点火源适用于任何特定用途，因为这是相关火灾危险的函数（另请参见 5.2 ). 1.3 这种做法不一定全面，也可能存在其他适用的点火源（另请参阅 5.3 ). 1.4 本规程描述了燃烧和非燃烧点火源，因为非燃烧点火源的结果可能是这些材料或产品的最终燃烧点火源（另请参见 4.2 ). 1.5 本规程未提供可用作监管工具的合格/不合格标准。 1.6 本消防标准不能用于提供定量措施。 1.7 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.8 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.9 本惯例包含提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.10 以国际单位制表示的数值应视为裁判决定的标准值。 本标准不包括其他计量单位。看见 IEEE/ASTM SI 10 了解更多详细信息。 1.11 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。 1.12 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====== 5.1 许多不同的标准制定组织和监管机构发布了各种标准测试方法、规范和法规，其中包含用于评估火灾的点火源- 与燃烧和非燃烧点火相关的测试响应特性。本规程描述了此类点火源，并提供了有关描述这些点火源的标准方法的信息。 5.2 为任何特定用途选择的点火源需要与预期应用相关的火灾危险相关。包含点火源的标准范围或标准的任何其他方面均不影响点火源在其他应用中的使用。 5.3 本规程预计不会是一份全面的点火源清单。如果确定了其他点火源，则可以将其添加到实践中。 5.4 本规程不描述材料或产品的试样制备或详细测试程序。 5.5 本规程不涉及与本规程中所述点火源相关的限制。 5.6 本规程不一定涉及任何引用标准的最新版本。

1.1 This practice describes a series of ignition sources that have been used and that are potentially applicable to assessing fire-test-response characteristics resulting from the ignition of materials, products, or assemblies. 1.2 This practice does not identify which of the ignition sources described is applicable to any specific use since that is a function of the associated fire hazard (see also 5.2 ). 1.3 This practice is not necessarily comprehensive and it is possible that other applicable ignition sources exist (see also 5.3 ). 1.4 This practice describes both flaming and non-flaming ignition sources, since the outcome of a non-flaming ignition can be the eventual flaming ignition of these materials or products (see also 4.2 ). 1.5 This practice does not provide pass/fail criteria that can be used as a regulatory tool. 1.6 This fire standard cannot be used to provide quantitative measures. 1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.9 This practice contains notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the standard. 1.10 The values stated in SI units are to be regarded as standard in referee decisions. No other units of measurement are included in this standard. See IEEE/ASTM SI 10 for further details. 1.11 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. 1.12 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 ====== 5.1 A variety of standard test methods, specifications, and regulations have been issued by a number of different standards developing organizations and regulatory authorities that contain ignition sources used to assess fire-test-response characteristics associated with flaming and non-flaming ignition. This practice describes such ignition sources and provides information on the standard method in which they are described. 5.2 The ignition source to be chosen for any specific use needs to be relevant to the fire hazard associated with the intended application. Neither the scope of the standard containing the ignition source nor any other aspect of the standard has any bearing on the use of the ignition source for another application. 5.3 This practice is not expected to be a fully comprehensive list of ignition sources. If additional ignition sources are identified they can be added to the practice. 5.4 This practice does not describe test specimen preparation or detailed testing procedures for the materials or products. 5.5 This practice does not address limitations associated with the ignition sources described in this practice. 5.6 This practice does not necessarily address the latest edition of any standard referenced.
