Annex - Recommendation of Test Procedures for Ignitability of Primary Deck Coverings

  1 Scope

 In accordance with the provisions of the International Convention for the Safety of Life at Sea, 1974, and subsequent amendments thereto, primary deck coverings, if applied within accommodation and service spaces and control stations, should be of approved materials which will not readily ignite, or give rise to toxic or explosive hazards at elevated temperatures. This Recommendation specifies a procedure for evaluating the ignitability of the primary deck coverings. Toxic and explosive hazards of the primary deck coverings should be verified to the satisfaction of the Administration.

  2 Field of Application

  2.1 Taking into account the wide range of materials used as coverings and their application, this Recommendation should be applied to those deck coverings which are laid upon a steel deck plate and beneath a surface material, if applied, of the floor. However, thin films such as paints may be exempted from consideration.

  2.2 If a deck covering applied on a steel deck plate is exposed and no other floor covering is provided, the deck coverings in areas where low flame spread materials are required should meet the requirements of floor coverings specified in the Recommendation on improved fire test procedures for surface flammability of bulkhead, ceiling and deck finish materials, adopted by the Organization by Resolution A.653(16).

  2.3 If the deck covering has a multilayer construction, the Administration may require the tests to be conducted for each layer or for combinations of some layers of the deck covering.

  3 Test Procedure

 The deck covering should be tested in accordance with the Recommendation on improved fire test procedures for surface flammability of bulkhead, ceiling and deck finish materials, adopted by the Organization by Resolution A.653(16), and additional provisions given below.

  3.1 Specimen

The deck covering should be applied to a steel plate having the thickness of 3 0.3 mm. The specimens should have a nominal thickness and the components and construction of the deck covering should be the same as those used in practice.

  3.2 Classification

The deck covering is classified as not readily ignitable if it fulfils the requirements of floor coverings specified in paragraph 10 of the annex to Assembly resolution A.653(16) and does not produce burning droplets.
