Overview

This European Standard specifies a method for the determination of the staining tendency of bitumen. This method is applicable to bitumen having a Ring-and-Ball softening point which is greater than or equal to 80 °C. For softer bitumen, the test conditions may be modified by agreement between the involved parties. The method described in this document may be used to compare results against a material for which the staining tendency is known. WARNING - The use of this standard may involve the handling of hazardous materials and equipment, as well as carrying out dangerous operations. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to clarify prior to use, if regulatory limitations need to be taken into account. A retaining ring, filled with molten bitumen and placed on a flat horizontal plate which is covered by a sheet of filter paper, is heated in an oven at a specified temperature and for a specified time. The width of the resulting stained circle around the bitumen is calculated to determine the staining tendency of the bitumen. The staining tendency has the dimension of length and results are rounded to nearest 0,5 mm. The Committee responsible for this standard is NA 062-03-32 GA "Gemeinschaftsausschuss NMP/NABau/FGSV 7.2.0.1: Bitumen; Prüfverfahren und Anforderungen für Bindemittel" ("Joint working group NMP/NABau/FGSV 7.2.0.1: Bitumen; test methods and specifications of binders") of DIN.
