The GB/T 19666 Toxicity Index Tester is used for smoke toxicity testing in accordance with multiple international and regional standards. Typical application scenarios include:
Flame-retardant and fire-resistant power cables
Railway rolling stock cables and signal cables
Optical fiber cables and communication cables
Polymer insulation and sheath materials
Halogen-containing and halogen-free cable compounds
The instrument supports both absorption-liquid analysis and gas bag collection methods, allowing flexible downstream analysis depending on the test standard and laboratory requirements.
Standards
The system complies with the following standards and test methods:
(1) GB/T 19666 – General Rules for Flame-Retardant and Fire-Resistant Wires, Cables or Optical Cables
(2) EN 50305 – Railway Applications – Test Methods for Fire Behaviour of Electric Cables
(3) BS 6853 Annex B – Code of Practice for Fire Precautions in the Design and Construction of Passenger Carrying Trains
(4) ISO 19700 – Controlled Equivalence Ratio Method for the Determination of Toxic Product Yields in Fire Effluents (Steady-State Tube Furnace Method)
