IS 694:2010 & IS 17048:2018 — Reaction to Fire Metrics
Cable Fire Performance: Toxicity & Visibility Dashboard
80% of fire casualties are caused by toxic smoke inhalation. See how different insulation polymers behave during combustion under BIS test conditions.
Engineering Note — Reaction vs. Circuit Integrity: FR, FR-LSH, and HFFR ratings define a cable's Reaction to Fire (flame spread, smoke, toxicity). Do not confuse these with Fire Survival (FS) Cables, which use mica-glass tapes to maintain continuity during an active fire (IEC 60331/BS 6387).
FR Cable
Flame Retardant (PVC)
HCl Emission (Toxicity)>15%
FR-LSH Cable
Low Smoke Halogen (PVC)
HCl Emission (Toxicity)<15%
HFFR Cable
Halogen Free (ATH Compound)
HCl Emission (Toxicity)<0.5%
Cable Chemistry & Toxicity Data Matrix
| Cable Type | IS Standard | HCl Emission Limit | Light Transmittance (Smoke) |
|---|
| FR (Flame Retardant) | IS 694:2010 | > 15% (High) | < 40% (Poor) |
| FR-LSH (Low Smoke Halogen) | IS 694:2010 | < 15% (Moderate) | > 40% (Moderate) |
| HFFR (Halogen Free Flame Retardant) | IS 17048:2018 | < 0.5% (Negligible) | > 90% (Clear) |
