1.1 本规范适用于制造成预成型形状的硬质弹性多孔材料，用作垫圈和密封材料，以压缩密封或垫圈的形式，或两者兼有，用于其他建筑接缝的玻璃安装。 注1: 对于二次密封应用中使用的较软的多孔弹性材料，请参阅规范 D1056号 . 1.2 试验方法 C1166 如本规范所述，应用于测量和描述受控实验室条件下材料、产品或组件对热和火焰的响应特性，而不应用于描述或评估实际火灾条件下材料、产品或组件的火灾危险或火灾风险。然而，该测试结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。 1.3 以下预防性警告仅适用于试验方法部分第节 11 ，本规范: 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 对本标准具有管辖权的委员会不知道其他组织发布的任何类似标准。 1.5 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====== 9.1 火焰传播: 9.1.1 本规范有两种选择: 9.1.1.1 方案一- 需要进行火焰传播试验。 9.1.1.2 方案二- 不需要进行火焰传播试验。 9.1.2 如果未指定选项，则选项I将适用。 9.2 本规范有两个与耐臭氧性相关的分类。它们是I型和II型，后者对臭氧具有更大的阻力。参考本规范时，应指定类型，但如果未指定类型，则应适用类型II。 注2: 本规范中包含II型，用于需要更大耐臭氧性的地方。

1.1 This specification applies to those elastomeric cellular materials of a firm grade that are manufactured in preformed shapes for use as gaskets and for use as sealing materials, in the form of compression seals or gaskets, or both, for glazing other building joint applications. Note 1: For softer cellular elastomeric materials used in secondary sealing applications, refer to Specification D1056 . 1.2 Test Method C1166 , as referenced in this specification, should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 1.3 The following precautionary caveat pertains only to the test method portion, Section 11 , of this specification: 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 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.5 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 ====== 9.1 Flame Propagation: 9.1.1 This specification has two options: 9.1.1.1 Option I— Flame propagation test is required. 9.1.1.2 Option II— Flame propagation test is not required. 9.1.2 In case no option is specified, Option I will apply. 9.2 This specification has two classifications as related to ozone resistance. These are Type I and Type II, with the latter having the greater resistance to ozone. The type should be specified when making reference to this specification but in the event that the type is not specified, Type II shall apply. Note 2: Type II is included in this specification for use where greater ozone resistance is required.
