<p>This document specifies a method for the determination of the viscosity number of dilute solutions of polyamides in certain specified solvents.</p>
<p>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.</p>
<p>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.</p>
<p>The viscosity number is determined by the general procedure specified in ISO 1628‑1, observing the particular conditions specified in this document.</p>
