Temperature Stability is Critical for ASTM D445 Kinematic Viscosity

Temperature control is the single most important parameter for obtaining accurate and precise kinematic viscosity measurements. For petroleum products even more so, as their rate of viscosity change per unit of temperature is significantly greater than other types of materials. Thus, a slight variation in temperature can have a very large effect on the viscosity […]

Kinematic Viscosity Testing Advice for ASTM D445 KV Test

The entire length of the viscometer must be maintained at the appropriate temperature. The type of circulator used, the age of the bath fluid, and the bath fluid viscosity will impact temperature uniformity. The circulator and the viscosity of the KV bath fluid need to be balanced to provide a uniform temperature throughout the bath. […]
