scope:

This International Standard applies to the structural fire protection of large FRP yachts of 24 m in length and over, and carrying up to 12 passengers. The International Standard is not applicable to vessels subject to SOLAS.

By using the heat transfer Fourier Number, the International Standard determines the equivalency of any proposed insulated FRP sandwich laminate to the model insulated sandwich laminate based on a fire tested insulated laminate approved in accordance with IMO FTP Code as a fire-resisting division.

The method considers the relevant mechanical, thermal, and physical properties of the insulation and the FRP laminate.

The technology of the elements of the insulation and FRP resistance to heat, smoke, and fire used in the International Standard and the effectiveness of the insulation are applicable in general to insulated FRP as a fire-resistant material.

This International Standard does not cover the heat, fire, smoke resistance of the attachments of insulation to the laminate, of penetrations, doors, windows, hatches, or of any other detail in insulated laminate divisions that might impair the heat, fire, and smoke resistance performance of the divisions
