BS EN ISO 12058-1:2018规定了使用倾斜？管子掉下来了？球形粘度计，用于测定聚合物和树脂在液体乳化或分散状态下的粘度。适用于粘度测量范围为0.6 mPa·s至250 000 mPa·s（温度范围-20°C至+120°C）的液体，剪切应力与剪切速率成正比，即粘度与剪切速率无关。这种理想行为通常被称为牛顿行为。如果一种液体与这种行为有显著差异，那么不同的落球会产生不同的结果？球形粘度计或不同几何形状的粘度计，如毛细管粘度计和旋转粘度计。交叉引用:ISO 2811-1DIN 53015:2001DIN 53015:1978购买本文件时可获得的所有现行修订均包括在购买本文件中。

BS EN ISO 12058-1:2018 specifies the general principles of a method, using an inclined?tube falling?ball viscometer, for determining the viscosity of polymers and resins in the liquid emulsified or dispersed state. It is intended for application to liquids over a viscosity measurement range of 0,6 mPa·s to 250 000 mPa·s (temperature range-20 °C to +120 °C) for which the shear stress and shear rate are proportional, i.e. the viscosity is independent of the shear rate. This ideal behaviour is commonly known as Newtonian behaviour. If a liquid differs significantly from this behaviour, different results can be obtained with the different balls of a falling?ball viscometer or from viscometers with different geometries, such as capillary and rotational viscometers.Cross References:ISO 2811-1DIN 53015:2001DIN 53015:1978All current amendments available at time of purchase are included with the purchase of this document.
