![]() ![]() With embedded thermal printer, its printing is quieter, faster and clearer.ġ.Dynamic timing, automatic calculation, automatic conversion of viscosity index. Title, ASTM Viscosity Tables for Kinematic Viscosity Conversions and Viscosity Index Calculations Volume 43 of ASTM special technical publication, American.The capillary viscometer clip cover designed by Lee is easy to install and remove.Slot LED lighting, illuminate the capillary engraved line, clear and not dazzling.With temperature correction function, the correction value will be lost after power off.Layer of transparent round glass constant temperature bath: 20L glass tank thermal insulation explosion-proof. The viscosity index is not defined and shall not be reported for oils with kinematic viscosity of less than 2.0 mm2/s at 100 C.At the same time, it has the function of authority management, which can effectively prevent non-professionals from setting key parameters of the analyzer. Large LCD display, self-developed embedded system for temperature control, plastic injection molding integrated display screen frame is beautiful and elegant full Chinese operation interface, intuitive display. Then take the arithmetic mean value of flowing time for no less than 3 times to be the average flowing time of sample.This instrument is based on the People's Republic of China standard GB/T 265 and ASTM D445 "Petroleum Products Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method", which is suitable for measuring the kinematic viscosity of liquid petroleum products (referring to Newtonian liquid) and dark petroleum products it can also measure viscosity index of oils and related substances. The difference between every flowing time and its arithmetic mean value needs to meet the following requirements: no more than ☐.5% of the mean value at testing temperature of 100-15℃ no mare than ☑.5% at 15~ -30℃ no more than ☒.5% at lower than -30℃. The flowing time recorded by stopwatch needs to be repeatedly tested at least four times. ![]() 5-expansion part 4-capillary a 、b-marking linesĦ. Start the stopwatch when liquid level exactly reach marking line a, and stop it when liquid level exactly reaches marking line b.ġ. At this time observe the flowing condition of sample in the tube body. Viscosity Index (VI) mode This mode tests at two different temperatures (typically +40 ☌ and +100 ☌). ![]() Use the rubber tube covered on capillary viscometer body 1 port to inject the sample into expansion part 3, make the sample liquid level a little higher than the marking line a, and pay attention not to make bubble or gap generated on the liquid levels of capillary and expansion part 3.ĥ. Author: American Society for Testing Materials Note. When using the fully immersed type thermometer, please refer to the required calculation formula in standard to calculate the correction number.Ĥ. Title: ASTM viscosity tables for kinematic viscosity conversions and viscosity index calculations. You need make the mercury ball position near to the level of capillary middle point, and make the thermometer scale which will test temperature at 10mm above the bath. When fix the position, the expansion part 2 of capillary viscometer must be dipped for half part.ģ. The test temperature must be kept constant within ☐.1℃. ![]() Adjust the constant temperature bath to be at specified temperature, dip the viscometer into the bath to be preheated (refer to the standard for preheating time). Fix the viscometer which is filled well with sample on the viscometer clip cover and adjust it to vertical situation.Ģ.
