This term is interchangeable with LSZH (Low Smoke Zero Halogen), LSOH (Low Smoke Zero Halogen), OHLS (Zero Halogen Low Smoke) and FRNC (Flame Retardant Non-Corrosive). Beware of the terms LSF (Low Smoke and Fume) or RP (Reduced Propogation), when relating to signal or control cables will normally be modified PVC and produce 'Loads of Smoke and Fume'!

These terms are often misunderstood. Most cables when exposed to fire will not carry on functioning. If you require cable to continue working in the event of fire, and in accordance with various standards please call us.
