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 crossli ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
