I. Summary
The instrument is made as per T0622 Asphalt Engler Viscosity Test (Engler Viscometer Method) in the industrial standard of People’s Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering, the national standard of People’s Republic of China GB/T 266 Test Methods for Engler Viscosity of Petroleum Products and the enterprise standard of Shanghai municipality Q/YXYY11 WNE-1A Engler Viscometer. It is suitable to determine ratio between the time used by an asphalt sample or other petroleum products sample flowing out of Engler viscometer under a certain temperature and volume, and that of distilled water flowing out of Engler viscometer at 25 ℃. The ratio is the Engler viscosity of asphalt or other petroleum products.
Notification: The temperature of distilled water and the cubage of receiving flask may be different for other petroleum products measurement.
