本文件规定了测定稀释溶液中有机聚合物的还原粘度、特性粘度和K值的一般条件。它定义了用于粘度测量的标准参数。 本文件用于制定测量各种聚合物溶液粘度的标准。它还用于测量和报告聚合物在溶液中的粘度，该溶液没有单独的标准。

This document defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement. This document is used to develop standards for measuring the viscosities in solution of individual types of polymer. It is also used to measure and report the viscosities of polymers in solution for which no separate standards exist.
