it is comfortable to wear;
it allows the wearer to jump from a height of at least 4.5 metres into the water without injury and without dislodging or damaging the lifejacket.
It shall be so constructed that the buoyancy is not reduced by more than 5% after 24 hours submersion in fresh water.
It shall be fitted with a whistle firmly secured by a cord of suitable length. The whistle shall be non-metallic and not be adversely affected by water or humidity.
It shall be fitted with an approved light.
