11、DIN EN 1049-2 EN 12127 DIN EN 12127 DIN ISO 20712-2:2008-08 Introduction There is a need to standardize a system of giving safety information that relies as little as possible on the use of words to achieve understanding. Continued growth in international trade, travel and mobility of labour require
12、s a common method of communicating safety information. Lack of standardization may lead to confusion and perhaps accidents. The use of standardized beach safety flags does not replace proper work methods, instructions and accident prevention training and/or measures. Education is an essential part o
13、f any system that provides safety information. NOTE Some countries statutory regulations may differ in some respects from those given in this part of ISO 20712.

14、712-2:2008-08 IMPORTANT The colours represented in the electronic file of this International Standard can be neither viewed on screen nor printed as true representations. Although the copies of this International Standard printed by ISO have been produced to correspond (with an acceptable tolerance
15、as judged by the naked eye) to the requirements of this part of ISO 20712, it is not intended that these printed copies be used for colour matching. 1 Scope This part of ISO 20712 specifies requirements for the shape and colour of beach safety flags for the management of activities on coastal and in
16、land 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 physic
17、al 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. NOTE The illustrations in this part o
