IMO 2010 FTPC Part 2 (IMO Resolution MSC.307(88) Annex 1 Part 2) - Smoke and toxicity test Materials for maritime use are tested according to the IMO 2010 FTP Code (International Maritime Organization Fire Testing Procedures Code). Results can be used for type approval (wheel mark). The specimen is inserted into a horizontal position under the cone radiator inside the smoke density chamber. During the test specimen starts to emit smoke which is collected in the closed chamber. Density of smoke is detected optically. When making toxicity measurements with FTIR concentrations of carbon monoxide (CO), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen fluoride (HF), hydrogen cyanide (HCN), nitrogen oxides NO_x (NO + NO₂) and sulphur dioxide (SO₂) are measured. Classification criteria of Smoke An average (D_m) of the maximum of D_s of three tests at each test condition should be within the following limits: D_m 200 for materials used as the surface of bulkheads, linings or ceilings D_m 400 for materials used as primary deck covering D_m 500 for materials used as floor covering D_m 400 for plastic pipes and electric cables Classification criteria of Toxicity The gas concentrations measured at each test condition should be within the following limits: CO 1450 ppm HCl 600 ppm HBr 600 ppm HF 600 ppm HCN 140 ppm NO_x 350 ppm SO₂ 120 ppm (200 ppm for flooring)
