ISO 9128:2006
Scope
This International Standard specifies the graphical
symbols and colours used to identify, on road
vehicles, the correct type of fluid to be used for:
a) petroleum-base brake fluid systems;
b) non-petroleum-base brake fluid systems.
NOTE 1 Should future technical development add
further classifications of fluids, new additional symbols will
be designated.
NOTE 2 The same symbols are also used for labelling
the fluid containers (see ISO 3871).
