However, depending on the application, these are often either too general, too specific or not available for the specific case. In order to warn the user as precisely as possible, safety signs must therefore be created on the basis of ISO 3864. ISO 9186 provides a clear indication of whether these safety signs are recognized with sufficient accuracy, with test methods for comprehensibility, visual quality and association with the subject of the symbol.</description></oembed>
