LSF0H - Check to be sure what you get
See what happens when HFT/LSF0H installations and PVC installations start to burn
Low Smoke (LS)
Flame Retardancy (F)
To avoid flame propagation, conduits have to be flame retardant. Halogen-free conduits need specific additives, PVC is genuinely flame retardant. Conduits that comply with IEC 61386 can be labelled "flame retardant"
Zero Halogen (0H)
Halogens are dangerous because they create aggressive gases and fumes in case of fire, even if released in small quantities. PVC contains chlorine and therefore is not halogen-free. Halogen-free plastics have to comply with IEC 60754.
