The SOLAS international convention is administered by the International Maritime Organization (IMO). Today, SOLAS covers almost all types of commercial ships engaged in international service and has been ratified by all major maritime nations.

IMO methods (based on SOLAS agreement) concerning the reaction to fire properties of surface lining materials consist of 11 test methods (see table below).

Some main resolution are detailed below:
  • RESOLUTION A.653(16) : recommendation on improved fire test procedures for surface flammability of bulkhead, ceiling and deck finish materials. 
    Experimental results are reported in terms of: heat for ignition, heat for sustained burning, critical flux at extinguishment and heat release of specimen during burning. In this method heat release calculation is based on the temperature measuring.

  • RESOLUTION A.687 (17) : fire test procedures for ignitability of primary deck coverings.
    This resolution specifies a procedure for evaluating the ignitability of the primary deck coverings. The deck covering should be tested in accordance with the previously described Res A.653 (16). The deck covering is classified according to the requirements of floor coverings specified in Res.A.653(16).

  • RESOLUTION MSC.41(64) : interim standard for measuring smoke and toxic products of combustion.
    This standard specifies a procedure for qualifying smoke generation and toxic potency of materials used on board ships. Smoke generation tests should be conducted, in general, in accordance with the ISO 5659-2. When making toxicity measurements, the sampling fumes should be made during the testing of the second or the third specimen at each test condition, from the geometrical centre of the chamber within 3 min of the time when the maximum optical density of smoke is reached. The concentration of each toxic gas is determined as ppm in the chamber volume. The following gases are measured: CO, CO2, HCl, HBr, HF, HCN, NOX, SO2, acrolein and formaldehyde and shall no exceed the specified limits.

The concentration measured at each test should not exceed the following limits:
