What are the flame retardant standards for optical cable sheaths

Flame-Retardancy: The sheath material must meet specific fire resistance standards, such as UL 94 V-0 or IEC 60332-1. These standards ensure that the material does not propagate fire easily. When a cable ignites, two questions decide if a building, ship or factory survives: “how far will the flame travel?” and “how much heat and smoke will it release?” The International Electrotechnical Commission answers the first question with IEC 60332, “Tests on electric and optical-fibre cables. Below are the most commonly used fiber optic cable jacket materials and their key characteristics: Excellent moisture, abrasion, and corrosion resistance; good electrical and chemical stability; HDPE is harder and heat-resistant; LDPE is more flexible. Under the blowing of a forced fan, the flame spreads and extinguishes itself. Plenum-rated cables are tested to stringent plenum standards (NFPA-262 / former UL-910) that measure flame spread and smoke during an extended burn in a tunnel (Steiner or similar). Its structure is mainly composed of cable core, longitudinal covering a layer of two-sided synthetic mica tape outside cable core, inner sheath packed with ceramic sheathing materials, steel wire armor outside inner sheath, wrapping a layer of two-sided synthetic mica tape outside armor and then.
