Plastics - Polyamides - Determination of viscosity number (ISO 307:2019)
29-05-2019
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.
