ÖNORM EN 12596

This European Standard specifies a method for the determination of the dynamic viscosity of bituminous binders by means of a vacuum capillary viscometer at 60 °C in a range between 0,003 6 Pa s to over 580 000 Pa s. Bituminous Emulsions are not within the scope of this method. NOTE 1 Emulsions containing bituminous binders are not considered to be covered by this method. This method can be used for anhydrous binders obtained from emulsions (stabilised and/or recovered binders). NOTE 2 The viscosity behaviour of some polymer modified bitumens (PMB) is not demonstrated in a vacuum capillary viscometer. Other methods are more relevant. WARNING Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
