General rules for flame retardant and fire resistant electric wires and cables or optical fiber cables
1 Scope
This standard specifies the burning behavior code, technical requirements, test methods and acceptance rules of flame retardant and fire resistant electric wires and cables or optical fiber cables, including the burning behavior of halogen-free, low smoke, low toxicity, flame retardance and fire resistance.
This standard is applicable to flame retardant and fire resistant electric wires and cables or optical fiber cables containing halogen, halogen-free or with low smoke or low toxicity.
