Standard Test Method for Evaluating the Fire-Test-Response of Deck Structures to Burning Brands 评估甲板结构对燃烧品牌的耐火试验的标准试验方法
发布日期: 2017-12-15
1.1 本试验方法确定了连接到主要结构或靠近主要结构的甲板结构的火灾试验响应特性。燃烧痕迹暴露试验旨在确定当暴露于甲板结构上表面的燃烧痕迹时,甲板材料的降解模式。 1.2 出于防火目的使用油漆、涂料、污渍或其他表面处理不在本试验方法的范围内。本试验方法不包括使用油漆、着色剂或涂料来确定火灾试验响应。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值;因此,每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.4 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。 1.5 产品和材料的防火测试具有固有的危险性。在进行这些测试时,应采取适当的人员和财产保护措施。 1.6 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。 1.7 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 本试验方法旨在制定桥面材料和系统的试验方案。本试验方法旨在解决由涉及甲板或结构上表面的外部源引起的火灾。 4.2 本试验是对规定火灾荷载下火灾试验响应特性的实际评估。本试验方法是试验方法的变体 E108 .
1.1 This test method determines the fire-test-response characteristics of deck structures attached to or in close proximity to primary structures. The burning brand exposures test is intended to determine the degradation modes of decking materials when exposed to a burning brand on the upper surface of a deck structure. 1.2 The use of paints, coatings, stains, or other surface treatments for fire protection purposes are beyond the scope of this test method. This test method excludes the use of paints, stains, or coatings for this fire-test-response determination. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 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. 1.5 Fire testing of products and materials is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.6 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. 1.7 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 test method is intended to establish the test protocol for decking materials and systems. This test method is intended to address a fire caused by exterior sources that involves the upper surface of the deck or structure. 4.2 This test is a practical assessment of fire-test-response characteristics under a prescribed fire loading. This test method is a variation of Test Method E108 .
