This European Standard specifies a method for the determination of the staining tendency of bitumen.

NOTE 1 Staining properties are related to the colloidal stability of the bitumen with higher values indicating lower stability.

The method is applicable to bitumen having a ring-and-ball softening point greater than or equal to 80 °C.

NOTE 2 For softer bitumen the test conditions may be modified by agreement between the involved parties.

The procedure described in this standard may be used to compare results against a material for which the staining tendency is known.
