This document describes the measurement of the toxicity potential of the products of combustion based on two test methods:
  • — Method 1: EN ISO 5659‑2 Smoke chamber area-based test with Fourier transform infrared spectroscopy (FTIR) gas analysis techniques;
  • — Method 2: NF X70‑100‑2 Tubular furnace small mass-based test.

NOTE 1 This document also specifies test equipment and set out the calculation procedures for evaluation of toxicity data.

NOTE 2 This document can be used in addition to others for the determination of toxic gases from devices installed in tunnel.
