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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders - Sampling bituminous binders EN 12594, Bitumen and bituminous binders - Preparation of test samples EN ISO 3696:1995, Water for analytical laboratory use - Specification and test methods (ISO 3696:1987) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 dynamic viscosity ratio between the applied shear stress and the velocity gradient NOTE 1 Dynamic viscosity is a measure of the resistance to the flow of a liquid and is commonly called the viscosity of the liquid. For the purposes of this standard, the word viscosity means the dynamic viscosity of a liquid. NOTE 2 The SI unit of dynamic viscosity is Pa · s. 3.2 Newtonian liquid liquid with a viscosity that is independent of the rate of shear NOTE The constant ratio of the shear stress to the velocity gradient is the dynamic viscosity of the liquid. If this ratio is not constant, the liquid is non-Newtonian. 3.3 density mass of a liquid divided by its volume NOTE 1 When reporting density, the unit of density used, together with the temperature, is stated explicitly, for example kilogram per cubic metre. NOTE 2 The SI unit of density is kg/m3.

When thermometers are completely submerged, corrections for each individual thermometer based on calibration under conditions of complete submergence are determined and applied.
If the thermometer is completely submerged in the bath during use, the pressure of the gas in the expansion chamber will be higher or lower than during standardization, and can cause a high or low reading on the thermometer. 5.2.2 It is essential that liquid-in-glass thermometers be recalibrated periodically and that official corrections be adjusted as necessary to conform to any changes in temperature readings. The thermometer shall be read as accurately as possible, any appropriate correction applied, and the corrected reading recorded to 0,1 °C. NOTE 1 Thermometers should be checked at regular intervals. NOTE 2 A commonly used procedure given in method ASTM E 77 applies a correction which is based on changes in the ice point calibration. Other temperature measuring devices may be used instead of mercury stem thermometers. However, the mercury stem thermometer is the reference device. Therefore any alternative device employed shall be calibrated so as to provide the same readings as would be provided by the mercury stem thermometer, recognising and allowing for the fact of changed thermal response times compared with the mercury thermometer. NOTE 3 When measuring and controlling nominally constant temperatures, as in this test method, alternative devices can indicate greater cyclic variations than mercury thermometers, to an extent depending on the cycle time of heating and the power of the controlled heat input.
