BS EN ISO 6185-4:2018

This standard BS EN ISO 6185-4:2018 Inflatable boats is classified in these ICS categories:

• 47.080 Small craft

This part of ISO 6185 specifies the minimum safety characteristics required for the design, materials, manufacture and testing of rigid inflatable boats (RIBs) with a hull length of between 8 m and 24 m and with a motor power rating of 15 kW and greater.

This part of ISO 6185 is applicable to Type IX and Type X RIBs intended for use within the operating temperatures of −20 °C to +60 °C.

• Type IX: Powered boats, fitted with a buoyancy tube covering at least 85 % of the port and starboard sides, suitable for navigation in inshore and sheltered waters, up to and including wind force 6 Beaufort and significant wave heights up to 2 m (design categories C and D), with a hull length of between 8 m and 24 m and with a motor power rating of 15 kW and greater.

• Type X: Powered boats, fitted with a buoyancy tube covering at least 85 % of the port and starboard sides, suitable for navigation in waters, up to wind force 8 Beaufort and significant wave heights up to 4 m (design category B), with a hull length of between 8 m and 24 m and with a motor power rating of 75 kW and greater.

NOTE 1 General arrangements of typical boats of Types IX and X are given in Annexes A and B, respectively.

NOTE 2 For boats with power ratings of 4,5 kW and less, refer to ISO 6185‑1. For boats with power ratings of 4,5 kW to 15 kW inclusive, refer to ISO 6185‑2. For boats with a hull length of less than 8 m and power rating of 15 kW and greater, refer to ISO 6185‑3.

Boats outside these types or outside of Type IX and Type X, as defined, are outside of the scope of ISO 6185.

NOTE 3 For inflatable boats with a hull length greater than 8 m, it is suggested to use the requirements of ISO 6185‑3.
