ISO 4575:2007规定了使用Severs流变仪测定由PVC糊聚合物和增塑剂制备的聚氯乙烯（PVC）糊在高剪切下的表观粘度的方法。 它尤其适用于根据ISO 4612或ISO 11468制备的“标准膏”。

ISO 4575:2007 specifies a method, using the Severs rheometer, for determining the apparent viscosity, at high shear, of poly(vinyl chloride) (PVC) pastes prepared from PVC paste polymers and plasticizers. It applies in particular to 'standard pastes' prepared in accordance with ISO 4612 or ISO 11468.
