注1: 本标准的大部分内容基于模型建筑规范评估服务 2. 标题为的验收标准 润滑脂管道外壳组件的验收标准，AC101 ，创建于1994年。根据本标准的规定，存在许多设计清单和标记材料。 1.1 这些测试方法使用以下测试方法评估外壳材料和润滑脂管道外壳系统:不燃性、耐火性、耐久性、内部火灾和穿透式阻火器的火灾吞没。 1.2 这些测试方法规定了标准化的火灾暴露，用于比较外壳材料和润滑脂管道外壳系统的测试结果。这些测试的结果是评估润滑脂管道外壳系统预测防火性能的一个因素。使用这些测试结果预测实际润滑脂管道外壳系统的性能需要评估测试条件。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 这些试验方法的文本参考了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）不应视为耐火试验响应标准的要求。 1.5 这些测试方法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。 1.6 这些试验方法并非旨在解决与其使用相关的所有安全问题（如有）。 这些测试方法的用户有责任在使用前建立适当的安全和健康实践，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====== 5.1 这些测试方法旨在评估润滑脂管道外壳系统执行以下操作的能力: 5.1.1 抵抗标准化火灾暴露的影响， 5.1.2 保持其完整性，或 5.1.3 根据预定试验暴露期间涉及的试验组件类型，展示这两种特性。 5.2 这些试验方法提供了以下测量和评估（如适用）: 5.2.1 当暴露于1382°F（750°C）时，外壳材料抵抗燃烧的能力。 5.2.2 在标准化火灾吞没试验期间，受试支撑系统和紧固系统承载润滑脂管道外壳系统负载的能力。 5.2.3 防火材料满足试验方法要求的能力 E814 与润滑脂管道外壳系统一起使用时。 5.2.4 在标准耐火试验和标准内部耐火试验期间，外壳材料抵抗火焰和热气体通过的能力。 5.2.5 在标准化耐火试验和标准化内部耐火试验期间，通过润滑脂管道和外壳材料的热量传输。 5.2.6 润滑脂管道外壳系统在标准化软管流测试期间抵抗水通过的能力。 5.2.7 当受到标准循环热传输时，外壳材料温度老化的比较测量。 5.3 这些试验方法不提供以下内容: 5.3.1 关于外壳材料或润滑脂管道外壳系统性能的完整信息，该系统由非测试部件、密度或尺寸构成。 5.3.2 评估外壳材料或润滑脂管道外壳系统通过产生烟雾、有毒气体或其他燃烧产物导致火灾危险的程度。 5.3.3 测量烟雾或燃烧产物通过润滑脂管道外壳系统的控制或限制程度。 5.3.4 测量润滑脂管道外壳系统表面上的火焰蔓延。 注2: 中的信息 5.3. 2 – 5.3.4 通常由其他合适的测试方法确定。例如 5.3.4 通常使用测试方法确定 E84 . 5.4 在这些试验方法中，在实验室条件下对试样进行一次或多次特定试验。当替换不同的试验条件或改变最终使用条件时，这些试验方法并不总是能够预测测量特性的变化。因此，这些实验室试验的结果仅对这些试验方法中描述的暴露条件有效。 5.5 这些试验方法中的各种试验方法要求将试样暴露在标准火中，该火在规定的时间段内受控以达到规定的温度。火灾吞没和垂直耐火试验之后，应用标准化的软管流试验。 这些试验方法提供了在这些暴露条件下类似外壳材料和润滑脂管道外壳系统的耐火试验响应的相对测量。火灾暴露并非代表所有火灾条件，因为条件随火灾荷载的数量、性质和分布、通风、隔间大小和配置以及隔间散热器特性的变化而变化。试验条件或试样结构的变化（如尺寸、材料、装配方法）也会影响耐火试验响应。由于这些原因，需要对变更进行评估，以应用于现场施工。

Note 1: The majority of this standard is based on the Model Building Code Evaluation Service 2 Acceptance Criteria titled ACCEPTANCE CRITERIA FOR GREASE DUCT ENCLOSURE ASSEMBLIES, AC101 , which was created in 1994. Numerous design listings and labeled materials exist based on the provisions of this standard. 1.1 These test methods evaluate the enclosure materials and the grease duct enclosure systems using the following test methods: noncombustibility, fire resistance, durability, internal fire, and fire-engulfment with a through-penetration fire stop. 1.2 These test methods prescribe a standardized fire exposure for comparing the test results of the enclosure materials and grease duct enclosure systems. The results of these tests are one factor in assessing predicted fire performance of grease duct enclosure systems. Using these test results to predict the performance of actual grease duct enclosure systems requires the evaluation of test conditions. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The text of these test methods references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the fire test response standard. 1.5 These test methods are 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. 1.6 These test methods do not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of these test methods to establish appropriate safety and health practices and to 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 ====== 5.1 These test methods are intended to evaluate the ability of the grease duct enclosure system to do the following: 5.1.1 Resist the effects of a standardized fire exposure, 5.1.2 Retain its integrity, or 5.1.3 Exhibit both properties dependent upon the type of test assembly involved during a predetermined test exposure. 5.2 These test methods provide for the following measurements and evaluations where applicable: 5.2.1 Capability of the enclosure material to resist flaming (combustion) when exposed to 1382°F (750°C). 5.2.2 Loadbearing ability of the tested support system and fastening system to carry the load of the grease duct enclosure system during a standardized fire-engulfment test. 5.2.3 Ability of a fire stop to meet the requirements of Test Method E814 when used with a grease duct enclosure system. 5.2.4 Ability of the enclosure material to resist the passage of flames and hot gases during a standardized fire resistance test and a standardized internal fire test. 5.2.5 Transmission of heat through the grease duct and the enclosure material(s) during a standardized fire resistance test and a standardized internal fire test. 5.2.6 Ability of the grease duct enclosure system to resist the passage of water during a standardized hose stream test. 5.2.7 Comparative measurement of temperature aging of the enclosure material(s) when subjected to standardized cyclic thermal transmissions. 5.3 These test methods do not provide the following: 5.3.1 Full information as to performance of the enclosure material or the grease duct enclosure system constructed with components, densities, or dimensions other than those tested. 5.3.2 Evaluation of the degree by which the enclosure material or grease duct enclosure system contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion. 5.3.3 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the grease duct enclosure system. 5.3.4 Measurement of flame spread over the surface of the grease duct enclosure system. Note 2: The information in 5.3.2 – 5.3.4 is usually determined by other suitable test methods. For example, 5.3.4 is typically determined using Test Method E84 . 5.4 In these test methods, the test specimens are subjected to one or more specific tests under laboratory conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, these test methods to predict changes to the characteristics measured. Therefore, the results of these laboratory tests are valid only for the exposure conditions described in these test methods. 5.5 Various test methods in these test methods require a test specimen to be exposed to a standard fire that is controlled to achieve specified temperatures throughout a specified time period. The fire-engulfment and vertical fire resistance tests are followed by the application of a standardized hose stream test. These test methods provide a relative measure of the fire-test-response of comparable enclosure materials and grease duct enclosure systems under these exposure conditions. The fire exposure is not representative of all fire conditions because conditions vary with changes in the amount, nature and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. Variation from the test conditions or test specimen construction, such as size, materials, method of assembly, also affects the fire-test-response. For these reasons, evaluation of the variation is required for application to construction in the field.
