Flame retardancy – inhibits and delays the spread of flames along wires and cables, preventing the fire from escalating.
Fire resistance – the ability to maintain operation for a certain period of time under flame conditions, that is, to maintain circuit integrity.
Halogen-free – The materials used to make wires and cables do not contain halogens, and their combustion products are less corrosive.
Low halogen – The materials that make up wires and cables may contain halogens, but in low amounts.
Low smoke – When wires and cables burn, they produce less smoke and dust, meaning they have higher light transmittance.
Low toxicity -- The gases produced when wire and cable materials burn have low toxicity.
