标准范围

规定了两种测量方法:方法A（球位移法）:在给定温度下测定沥青的粘度，使用具有类似特性的沥青样品，通过测量用规定力拉的球在充满熔融沥青样品的测量管内穿过固定距离所需的时间来测定沥青的粘度。方法B（圆柱体旋转法）:通过一个由圆柱锥形体组成的系统，在给定温度下，在选定转速下测量物质的剪切应力，该系统在圆柱形容器中包含的物质中旋转。

Two methods for the measurement are specified: Method A (Ball displacement method): Determination of the viscosity of a pitch at a given temperature determined using a sample of pitch having similar characteristics by measurement of the time a ball, drawn by a defined force, requires to traverse a fixed distance within a measuring tube filled with the sample of molten pitch. Method B (Rotation of a cylindrical body method): Measurement of the shear stress of a substance at a selected rotational speed at a given temperature by means of a system composed of a cylindrical-conical body revolving in the substance contained in a cylindrical vessel.
