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 and 580 000 Pa⋅s. Other temperatures are possible if calibration constants are known. Bituminous emulsions are not within the scope of this method.NOTE 1Emulsions containing bituminous binders are not considered to be covered by this method. This method can be used for stabilized and/or recovered binders obtained from emulsions.NOTE 2The 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 identify the hazards and assess the risks involved in performing this test method and to implement sufficient control measures to protect individual operators (and the environment). This includes appropriate safety and health practices and determination of the applicability of regulatory limitations prior to use.
