This part of ISO 9650 specifies the design, performance and marking characteristics, and gives the test methods for inflatable liferafts of Type I:
-- having a carrying capacity of 4 to 12 persons;
-- applicable on small craft of hull length up to 24 m;
-- suitable for launching overboard from a height not exceeding 6 m;
-- divided into two groups (group A and group B);
-- designed for extended voyages, where high wind and significant wave heights may be experienced, but excluding abnormal conditions such as hurricanes;
-- completely self-sufficient;
-- prepared to meet serious emergencies without expectation of outside assistance;
-- and not voyaging in extreme zones (e.g. Southern Oceans).
Type II liferafts are specified in ISO 9650-2.
