What are regulations for all types of Life jacket ( Adult, child and infant ) used on ship as per SOLAS ?

Life-jackets:

An adult life-jacket shall be so constructed that

• shall not sustain burning or continue melting after being totally enveloped in a fire for a period of 2 seconds.
• at least 75% of persons, who are completely unfamiliar with the lifejacket, can correctly don it within a period of one min without assistance, guidance or prior demonstration;
• after demonstration, all persons can correctly don it within a period of one minute without assistance;
• it is clearly capable of being worn in only one way or, as far as is practicable, cannot be donned incorrectly;
• it is comfortable to wear;
• it allows the wearer to jump from a height of at least 4.5 m into the water without injury and without dislodging or damaging the lifejacket.
• shall have buoyancy which is not reduced by more than 5% after 24h submersion in fresh water.
• shall be fitted with a whistle firmly secured by a cord.

An adult lifejacket shall have sufficient buoyancy and stability in calm fresh water to:

•  lift the mouth of an exhausted or unconscious person not less than 120 mm clear of the water with the body incline backwards at an angle of not less than 20° from the vertical position;
• turn the body of an unconscious person in the water from any position to one where the mouth is clear of the water in not more than 5 s.
• shall allow the person wearing it to swim a short distance and to board a survival craft.

A child lifejacket shall be constructed and perform the same as an adult lifejacket except as follows:

• donning assistance is permitted for small children;
• it shall only be required to lift the mouth of an exhausted or unconscious wearer clear of the water a distance appropriate to the size of the intended wearer;
• assistance may be given to board a survival craft, but wearer mobility shall not be significantly reduced.
• In addition to the markings with approval information including the Administration which approved it, and any operational restrictions, a child lifejacket shall be marked with:
• the height or weight range for which the lifejacket will meet the testing and evaluation criteria recommended by the Organization in A.689.(17)
• a “child” symbol as shown in the “child’s lifejacket” symbol adopted by the Organization in A.760(18)
