Halogen Free Low Smoke and Flame-retardant
Compounds for Wires and Cables
1 Application Scope
This Standard specifies the classification, technical requirements, test methods,
inspection rules and packaging, marking, transportation and storage of halogen free
low smoke and flame-retardant compounds for wires and cables.
This Standard applies to sheath for halogen free low smoke and flame-retardant wires
and cables and optical cables, and insulation for halogen free low smoke and flame-
retardant wires and cables of rated voltage 3 kV and below.
This Standard applies to halogen free low smoke and flame-retardant compounds for
wires and cables, which is made by adding halogen free fire retardants and other
performance additives to one or multiple halogen free polymer or copolymer and by
mixing, plasticification, granulation.
This Standard applies to thermoplastic and cross-linking type halogen free low smoke
fire-retardant compounds for wires and cables.
NOTE For cross-linking products, the specified properties refer to the properties of material
after cross linking.
