This British Standard specifies minimum ultraviolet transmission
requirements for materials used in the construction of hats worn to give
some protection from solar ultraviolet radiation. Requirements for
dimensions, design and labelling are also included in the standard.
NOTE Babies up to six months are not adequately protected by hats and
should be fully shielded from the sun by other suitable means.
