标准摘要
[中文适用范围]： 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，使用具有相似特性的沥青样品，通过测量球被规定的力拉动的时间来确定，需要在充满熔融沥青样品的测量管内移动固定距离。 方法B（圆柱体旋转法）：通过由圆柱形-圆锥体组成的系统在给定温度下以选定的旋转速度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。 [外文原描述]： 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.
