This part of SLNS/ISO 20712 specifies requirements for the shape and colour of beach safety
flags for the management of activities on coastal and inland beaches, to be used for giving
information on wind and water conditions and other hazardous conditions, and to indicate the
location of swimming and other aquatic activity zones extending from the beach into the
water. It also specifies the colorimetric and photometric properties and the physical
properties, including strength and colour fastness, of the materials from which beach safety
flags are to be made.
It is not applicable to flags for use on firing ranges or to flags for use to indicate water quality
or to signaling used for maritime traffic.
