► With the exception of freeboard and self-righting performance, the requirements for infant lifejackets may be relaxed, if necessary, in order to:
► facilitate the rescue of the infant by a caretaker;► allow the infant to be fastened to a caretaker and contribute to keeping the infant close to
the caretaker;► keep the infant dry, with free respiratory passages;► protect the infant against bumps and jolts during evacuation; and► allow a caretaker to monitor and control heat loss by the infant.

Lifejackets’ Type Testing
Inadvertent inflation test
► Expose the entire lifejacket to sprays of water for fixed period
Inflatable Lifejackets’ Type
Lifejacket fitted correctly to a free-standing manikin of adult size and deployed in the mode in which it is worn ready for use ( not deployed as used in the water)
Two sprays should be installed so as to spray fresh water onto the lifejacket
Acceptance criteria
500 mm above the highest point of the lifejacket & at an angle of 15° from the vertical centre line of the manikin and the bottom line of the lifejacket
Installed horizontally at a distance of 500 mm from the bottom line of the lifejacket, and points directly at the lifejacket
