EN 12595:2014 (E) 4 1 Scope This European Standard specifies a method for the determination of the kinematic viscosity of bituminous binders at 60 °C and 135 °C, in a range from 6 mm2/s to 300 000 mm2/s. Other temperatures are possible if calibration constants are known. Bituminous emulsions are not covered within the scope of this method. NOTE Emulsions containing bituminous binders are not considered to be covered by this method. The method can be used for recovered and/or stabilized binders

obtained from emulsions. Results for this method can be used to calculate dynamic viscosity when the density of the test material is known or can be determined. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. 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 12607-2, Bitumen and bituminous binders - Determination of the resistance to hardening under the influence of heat and air - Part 2: TFOT Method EN ISO 2592, Determination of flash and fire points - Cleveland open cup method (ISO 2592) 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 kinematic viscosity ratio between the dynamic viscosity and the density of a liquid at the temperature of viscosity measured Note 1 to entry: Kinematic viscosity is a measure of a liquid’s resistance to flow under gravity. Note 2 to entry: The Sl unit of kinematic viscosity is m2/s; for practical use, a sub-multiple (mm2/s) is more convenient. 3.2 density mass of a liquid divided by its volume Note 1 to entry: When reporting density, the unit of density used, together with the temperature, is explicitly stated, for example kilogram per cubic metre. SIST EN 12595:2014

EN 12595:2014 (E) 5 Note 2 to entry: The SI unit of density is kg/m3. 3.3 dynamic viscosity ratio between the applied shear stress and the velocity gradient Note 1 to entry: Dynamic viscosity is a measure of a liquid’s resistance to flow, and is commonly called the viscosity of the liquid. Note 2 to entry: The SI unit of dynamic viscosity is Pa„s. 3.4 Newtonian liquid liquid with a viscosity that is independent of the rate of shear Note 1 to entry: 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. 4 Principle The time for a fixed volume of the liquid to flow through the capillary of a calibrated glass capillary viscometer under an accurately reproducible head and at a closely controlled temperature is determined (efflux time). The kinematic viscosity is calculated by multiplying the efflux time in seconds by the viscometer calibration factor. 5 Apparatus Usual laboratory apparatus and glassware, together with the following: 5.1 Viscometer, CANNON-FENSKE, BS/IP/RF and the Zeitfuchs Cross-Arm viscometers, capillary-type, made of borosilicate glass, suitable for this method are described in Figure A.1, Figure A.2 and Figure A.3, and Table A.1, Table A.2 and Table A.3. Other viscometers are allowed if test results obtained are comparable. Calibrated viscometers are available from commercial suppliers. Details regarding the calibration of viscometers are given in Annex B. 5.2 Temperature measuring device

A temperature measuring device (combining sensor and reading unit) shall: — have a range from at least 55 °C to 140 °C, — be readable to 0,05 °C or less, and — have an accuracy of 0,1 °C or better. Sensors based on platinum resistance thermometers have been found suitable but other principles are also allowed. The thermal response time of the sensor shall be comparable with the former used reference (see informative Annex C). The temperature measuring device shall be calibrated regularly. A solid stem mercury thermometer (which used to be the former reference thermometer as described in Annex C) is also allowed if national regulations permit its use. The specified thermometers shall be standardized at total immersion; that is immersion to the top of the mercury column with the remainder of the stem and the expansion chamber at the top of the thermometer SIST EN 12595:2014

EN 12595:2014 (E) 6 exposed to room temperature. The practice of completely submerging the thermometer is not recommended. 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 high or low reading on the thermometer. It is essential that liquid-in-glass thermometers are recalibrated periodically and those official corrections be adjusted as necessary to conform to any changes in temperature readings. The thermometer shall be read, estimating the reading to 0,1 °C. Thermometers should be checked at regular intervals. A commonly used procedure given in method ASTM E77 [4] applies a correction that is based on changes in the ice point calibration. When measuring and controlling nominally constant temperatures, as in this test method, the thermal response time can be rather high (e.g. slow response to a change in temperature). Care shall be taken to consider this aspect since low thermal response times of the sensor can indicate greater cyclic variations than the bituminous material in practise experiences. 5.3 Bath, suitable for immersion of the viscometer so that the liquid reservoir or the top of the capillary, whichever is uppermost, is at least 20 mm below the top of the bath level, and with provisions for visibility of the viscometer and the thermometer. Firm supports for the viscometer shall be provided, or the viscometer shall be an integral part of the bath. The efficiency of the stirring and the balance between heat losses and heat input shall be such that the temperature of the bath medium does not vary by more than 0,3 °C (measurement at 60 °C) or 0,5 °C (measurement at 135 °C) over the length of the viscometer, or from viscometer to viscometer in the various bath positions. Water, conforming to the grade 3 of EN ISO 3696:1995, is a suitable bath liquid for determinations at 60 °C. USP white oil or any paraffinic or silicone oil with a flash point above 215 °C has been found suitable for determination at 135 °C. The flash point is determined in accordance with EN ISO 2592. 5.4 Timer, stop watch (spring or battery driven) graduated in divisions of 0,1 s or less and accurate to 0,5 s over 1 000 s when tested over intervals of not less than 15 min. 5.5 Electrical timing devices, for use only on electrical circuits the frequencies of which are accurate to 0,5 s over 1 000 s or better. NOTE Alternating currents, the frequencies of which are intermittently and not continuously controlled, as provided by some public power systems, can cause large errors, particularly over short timing intervals, when used to actuate electrical timing devices. 5.6 Automatic or semi-automatic equipment, are allowed providing that they meet the specifications for temperature regulation and time accuracy described in Clause 5 and have been shown to achieve the same precision as given in Clause 10 and are fully calibrated. 6 Preparation of test samples The laboratory sample shall be taken in accordance with EN 58. Prepare the sample in accordance with EN 12594. Bring the viscometer and the sample to the test temperature (in order to avoid correction of constants of the viscomet
