Scope
This part of GB/T 26930 specifies two methods for determining the dynamic viscosity of coal tar pitch used in the production of primary aluminum. For bitumen that conforms to Newtonian fluid properties, these two determination methods are equally valid, and either method can also be used to express it. Method A (ball displacement method) is applicable to asphalt that conforms to Newtonian fluid properties, such as the determination of the softening point of asphalt without adding other materials, at a temperature higher than the softening point but lower than 180 °C. Measuring range: 102 mPa·s~104 mPa·s. Method B (cylindrical rotation method) is suitable for the determination of asphalt that conforms to Newtonian fluid properties, and is also suitable for the determination of asphalt that does not conform to Newtonian fluid properties. They are either processed at high temperature (mesophase exists) or need to be measured at higher temperature (above 180 °C). This method can tell whether asphalt conforms to Newtonian fluid behavior. Measuring range: ≤3×106 mPa·s.
