  • Test Methods for Flame Retardancy of Communication Optical Cables

    Test Methods for Flame Retardancy of Communication Optical Cables

    The IEC 60332 gives a specification of standardized test methods to determine the flame propagation properties of electric and optical fibre cables when subjected to fire. 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. One of the most widely referenced international standards for flame retardant cables is IEC 60332, which evaluates how cables behave when exposed to flame conditions. Understanding IEC 60332 testing helps engineers, contractors, and project managers choose the right cable solutions to limit flame. l Committees).
