1.1 本指南旨在提供在光纤电缆中提供绝缘、护套和强度的组件中常用的材料列表。如果ASTM标准涵盖了这些材料，则应提供适当的参考。由于技术的变化，并非所有使用的材料都必须列在这里。 1.2 本指南不包括用于光学目的的组件（光纤及其涂层）或外部金属铠装（例如用于啮齿动物屏障）中的材料。 1.3 本指南提供了两个一般材料清单: 1.3.1 将光缆结构细分为用于绝缘、护套或强度的组件，每个组件中的特定应用具有通用材料分类（见第节） 5. )，和 1.3.2 按字母顺序排列的通用材料分类列表，显示ASTM标准（见 表1 ). 1.4 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 组件和材料清单有助于提高用户对纤维技术和结构的理解- 光缆和电缆性能标准的制定。 4.2 本指南适用于光纤相关各方:材料供应商、电缆制造商和最终用户。

1.1 This guide is intended to provide a list of materials commonly used in components that provide insulation, jacketing and strength in fiber-optic cables. Where these materials are covered by ASTM standards, an appropriate reference is made. Due to changing technology, not all materials being used are necessarily listed here. 1.2 This guide does not include materials used in components for optical purposes (optical fiber and its coating) or external metallic armoring (such as for a barrier to rodents). 1.3 This guide offers two general lists of materials: 1.3.1 A subdivision of fiber-optic cable construction into components that are used for insulation, jacketing, or strength, with a generic material classification for specific applications in each component (see Section 5 ), and 1.3.2 An alphabetical list of the generic material classifications, showing ASTM standards where they exist (see Table 1 ). 1.4 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 The lists of components and materials are useful in enhancing the user's understanding of the technology and construction of fiber-optics cables and the development of performance standards for cables. 4.2 This guide is intended for use by all parties involved with fiber optics: materials suppliers, cable manufacturers, and end-users.
