一、标准牛顿液体的粘度标准已经建立,但非牛顿流体的标准几乎不存在。牛顿液体的粘度标准包括:(1)由国家标准组织或其他在国家团体支持下的组织建立和保存的国家标准,(2)国家组织作为常规用的和那些使用组织作为参考保存的工作参考标准。后者为国家标准与工作仪器之间传递的桥梁。
First, the standard Newtonian liquid viscosity standards have been established, but the non-Newtonian fluid standards almost nonexistent. Viscosity standards for Newtonian liquids include: (1) National standards established and maintained by national standards organizations or other organizations supported by national groups; (2) Reference standards for national organizations as routine and those used as reference . The latter is a bridge between the national standard and the working apparatus.
