T/CAICI 7-2018 The technical specifications for optical cables with black polyethylene sheathing material

Scope

Scope: This standard specifies the product classification, requirements, test methods, inspection rules, packaging, marking, transportation, storage, and other items for black polyethylene sheathing materials used in optical cables. This standard applies to polyethylene sheathing materials specifically designed for optical cables, which are manufactured using polyethylene resin as the base material, supplemented with additives such as carbon black, antioxidants, and lubricants, and processed through mixing, extrusion, and granulation. The sheathing materials specified in this standard are not applicable to polyethylene sheathing materials with special requirements for flame retardancy or scratch resistance. Main technical content: This standard was developed based on the existing issues in the manufacturing, use, and inspection/evaluation processes of polyethylene sheathing materials for optical cables, and on the basis of extensive experiments conducted by enterprises and national testing centers. It refers to the relevant requirements of national and industry standards, expands the inspection items, and moderately raises some indicators, ensuring that the technical requirements of national and industry standards can be fully implemented. Additionally, this standard establishes a dedicated industry standard for these materials.
