ISO 20712-2:2007规定了海滩安全标志的形状和颜色要求，用于管理沿海和内陆海滩上的活动，用于提供风和水条件以及其他危险条件的信息，并指示游泳和其他水上活动区从海滩延伸到水里的位置。它还规定了制作海滩安全旗所用材料的色度和光度特性以及物理特性，包括强度和色牢度。 它不适用于靶场上使用的旗帜，或用于指示水质的旗帜，或用于海上交通的信号。

ISO 20712-2:2007 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 signalling used for maritime traffic.
