ÖNORM EN 14896

This European Standard specifies a method for the determination of the dynamic viscosity of bituminous emulsions, cut-back and fluxed bituminous binders, by means of a rotating spindle viscometer. There are standard application temperatures quoted, although the dynamic viscosity can be measured at other temperatures if required. Similarly, viscosity is quoted at standard rates of shear, although additional measurements can be taken at varying shear rates if required. NOTE Some bituminous materials may exhibit non-Newtonian behaviour under the conditions of this method. Since non-Newtonian viscosity values are not unique material properties, but reflect the behaviour of the fluid and the measurement system, it should be recognised that measurements made by this method may not always predict performance under the conditions of use. Comparisons between non-Newtonian viscosities should be made only for measurements under similar conditions of shear stress and shear rate. WARNING ¿ The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the esponsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
