Determination of Transparent and Opaque Liquids kinematic viscosity Automatic viscometer1 ScopeThis standard specifies the method for the determination of transparent and opaque liquid petroleum products kinematic viscosity automatic viscometer. This standard applies to shear stress and shear rate substantially proportional to the liquid (Newtonian fluid), the result depends on the traits measured sample. If there is a significant change in viscosity with shear rate, then use a different diameter capillary viscometer will get different results. Residual fuel oil Displayed under certain conditions non-Newtonian properties, measurement methods and procedures of the precision of the data has been considering this case. This standard Kinematic viscosity, temperature range is 20 ℃ ~ 100 ℃, kinematic viscosity range is 40 ℃ under 0.5mm2/s ~ 5000mm2/s, at 100 ℃ 1mm2/s ~ 2000mm2/s, allowing different instruments kinematic viscosity lower than this range.2 Normative referencesThe following documents for the application of this document is essential.

In the International System of Units (SI), the kinematic viscosity in units m2/s, said Unit is commonly used mm2/s. 3.2 Automatic viscometer automatedviscometer Kinematic viscosity measurement process includes many steps, injection (including sample warm-up), thermostatically controlled bath temperature, liquid level detection, timing, count Operators viscosity, cleaning and drying viscometer calibration, if all of the above steps are carried out automatically in accordance with the instrument, and its basic principles and hands Determination of kinematic viscosity of the same work, the instrument is called automatic viscometer.4 Method summaryAt a certain temperature, measured volume of liquid under gravity flow through a calibrated glass capillary viscometer time, the kinematic viscosity It is equal to the measured flow time and the viscometer constant of the product. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 3369-2012_English be delivered?Answer: Upon your order, we will start to translate SN/T 3369-2012_English as soon as possible, and keep you informed of the progress.
