ISO 3864

ISO 3864 specifies international standards for safety signs and markings in workplaces and public facilities. These labels are graphical, to overcome language barriers.[1] The standard is split into four parts:

  • ISO 3864-1:2011 Part 1: Design principles for safety signs and safety
  • ISO 3864-2:2016 Part 2: Design principles for product safety labels
  • ISO 3864-3:2012 Part 3: Design principles for graphical symbols for use in safety signs
  • ISO 3864-4:2011 Part 4: Colorimetric and photometric properties of safety sign materials

Colours

These are the colours specified in ISO Standard 3864-4 in RAL colour standard.[2]

The corresponding American standard is ANSI Z535, which is incompatible with the ISO standard. ANSI Z535.1 divides "Warning (Signal Yellow)" into two colors: Yellow (Pantone 109) for 'caution' messages, and Orange (Pantone 151) for stronger 'warning' messages.[4][5][6] Like ISO 3864, ANSI Z535 includes multiple sections: ANSI Z535.6-2006 defines an optional accompanying text in one or more languages.

ISO 3864 is extended by ISO 7010, which provides a set of symbols based on the principles and properties specified in ISO 3864.
