11、2007 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
12、 a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commiss
13、ion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical
14、committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall
15、not be held responsible for identifying any or all such patent rights. ISO 20712-2 was prepared by Technical Committee ISO/TC 145, Graphical symbols, Subcommittee SC 2, Safety identification, signs, shapes, symbols and colours. ISO 20712 consists of the following parts, under the general title Water
16、 safety signs and beach safety flags: Part 1: Specifications for water safety signs used in workplaces and public areas Part 2: Specifications for beach safety flags Colour, shape, meaning and performance Part 3: Guidance for use ISO 20712-2:2007(E) ISO 2007 All rights reserved v Introduction There
17、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 requires a common method of communicating safety information. Lack of standardization
18、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 of any system that provides safety information. NOTE Some countries statutory re
19、gulations may differ in some respects from those given in this part of ISO 20712. INTERNATIONAL STANDARD ISO 20712-2:2007(E) ISO 2007 All rights reserved 1 Water safety signs and beach safety flags Part 2: Specifications for beach safety flags Colour, shape, meaning and performance IMPORTANT The col
20、ours 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 as judged by the naked eye) to
21、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 inland beaches, to be used for gi
22、ving 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 streng
23、th 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 of ISO 20712 are as accurate as
24、possible within the limitations of the printing process. 2 Normative references The following referenced documents are indispensable for the application of this document.
