This British Standard specifies requirements for the safety of sleep
bags for the use of children with a minimum weight of 4 kg designed
to provide sufficient warmth so as to remove the need for additional
bedding when sleeping in a cot or similar product in which a child is
contained.
This standard does not apply to garments with sleeves and feet,
i.e. sleep suits or baby gros, or to products designed primarily
for outdoor use or to keep children warm when in a pushchair. It
also does not apply to sleeping bags covered by BS EN 13537 and
BS EN 13538.
NOTE Rationales for the inclusion of some of the requirements given in
this standard are given in Annex A.
