Cancels and replaces the second edition (1984). Specifies a method for the determination of the viscosity number of dilute solutions of polyamides in certain specified solvents that is applicable to polyamides as defined in ISO 1874-1, as well as to copolyamides and other polyamides that are soluble in one of the specified solvents under the specified conditions. Not applicable to polyamides produced by anionic polymerization of lactams or produced with crosslinking agents. The viscosity number is determined by the general procedure specified in ISO 1628-1, observing the particular conditions specified herein, and is a measure of the relative molecular mass of the polymer.
