标准摘要
[中文适用范围]： 本文件规定了测定聚酰胺稀溶液在某些特定溶剂中的粘度值的方法。 该方法适用于 PA 46、PA 6、PA 66、PA 69、PA 610、PA 612、PA 11、PA 12、PA 6T/66、PA 6I/6T、PA 6T/6I/66、PA 的聚酰胺ISO 16396-1 中定义的 6T/6I、PA 6I/6T/66 和 PA MXD6，以及在指定条件下可溶于指定溶剂之一的共聚酰胺、聚酰胺化合物和其他聚酰胺。 该方法不适用于由内酰胺阴离子聚合生产的或用交联剂生产的聚酰胺；此类聚酰胺通常不溶于特定溶剂。 粘度值是通过 ISO 1628-1 中规定的一般程序确定的，并遵守本文件中规定的特定条件。 [外文原描述]： This document specifies a method for the determination of the viscosity number of dilute solutions of polyamides in certain specified solvents. The method is applicable to the polyamides designated PA 46, PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA 6T/66, PA 6I/6T, PA 6T/6I/66, PA 6T/6I, PA 6I/6T/66 and PA MXD6 as defined in ISO 16396-1, as well as to copolyamides, compounds of polyamides and other polyamides that are soluble in one of the specified solvents under the specified conditions. The method is not applicable to polyamides produced by anionic polymerization of lactams or produced with cross-linking agents; such polyamides are normally insoluble in the specified solvents. The viscosity number is determined by the general procedure specified in ISO 1628‑1, observing the particular conditions specified in this document.
