IMO 2010 FTP Code Part 2 – Smoke and toxicity test

Smoke and toxicity testing by IMO 2010 FTP Code Part 2 is performed on surface materials to assess their suitability for marine use.

The specimen is placed in a horizontal position under a cone radiator inside a smoke-density chamber. During the test, the specimen starts to emit smoke, which is collected in the closed chamber. The density of smoke is detected optically.

When making toxicity measurements with FTIR, the concentrations of carbon monoxide (CO), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen fluoride (HF), hydrogen cyanide (HCN), nitrogen oxides NOₓ (NO + NO₂), and sulfur dioxide (SO₂) are measured.

Classification criteria for smoke

An average (Dₘ) of the maximum of Dₛ of three tests at each test condition should be within the following limits:

• Dₘ 200 for materials used as the surface of bulkheads, linings, or ceilings

• Dₘ 400 for materials used as a primary deck covering

• Dₘ 500 for materials used as a floor covering

• Dₘ 400 for plastic pipes and electric cables

Classification criteria for 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

• NOₓ 350 ppm

• SO₂ 120 ppm (200 ppm for flooring)
