This part of ISO 6185 is applicable to the following types of inflatable boats, intended for use within the operating temperatures of -15 oC to +60 oC: - Type V: Inflatable boats capable of takinga motor power ratingof 4,5 kW to 15 kW inclusive; - Type VI: Inflatable craft propelled by sail with a sail area greater than 6 m2 (see normative annex A). NOTE For boats with power ratings of 4,5 kW and less, refer ISO 6185-1, and for boats with power ratings of 15 kW and greater, refer to ISO 6185-3. This part of ISO 6185 excludes single-chambered boats and boats made from unsupported materials of more than 12 kN buoyancy and powered by motors exceeding 4,5 kW, and is not applicable to aquatic toys and inflatable liferafts.
