ISO 6185-3 specifies the minimum safety characteristics required for the design, materials, manufacture, and testing of inflatable and rigid inflatable boats. These boats must have a length of the hull (LH) in accordance with ISO 8666 less than 8 m and a motor power rating of 15 kW or greater.
The standard applies to the following types of boats intended for use within the operating temperatures of –20 °C to +60 °C:
— Type VII: Powered boats, fitted with a buoyancy tube on the port and starboard sides, suitable for navigation in conditions of design categories C and D.
— Type VIII: Powered boats, fitted with a buoyancy tube on the port and starboard sides, suitable for navigation in conditions of design category B.
ISO 6185-3 excludes single-chambered boats and boats with tubes made from unsupported materials and does not apply to aquatic toys and inflatable liferafts. Boats with tubes made from aluminium, roto-moulded polyethylene, fibre-reinforced plastic or other rigid materials are also excluded from this standard.
