Graphical symbols. Safety colours and safety signs - Colorimetric and photometric properties of safety sign materials PAS 15 and mass of fibre per1 Scope This part of ISO 3864 establishes the colorimetric and photometric requirements and test methods for the colours of safety signs to be used in workplaces and public areas. It provides the colorimetric and photometric specifications for the named safety and contrast colours prescribed in ISO 3864 1. The physical requirements that safety signs have to meet are primarily related to daytime colour and normally lit environments. This part of ISO
