Description of ASTM-D4967 2021ASTM D4967-21Active Standard: Standard Guide for Selecting Materials to Be Used for Insulation, Jacketing, and Strength Components in Fiber-Optic CablesASTM D4967Scope 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.
