Fineness can be considered as a vital characteristic of flax. However, because their special structure, the measurements of the fineness of such fibres presents a difficult problem. Two permeametric methods for the determination of the fineness of flax fibres are specified (a reference method, with two compressions, using a test piece of parallel fibres and a simplified method, with one compression, using a test piece of fibres distribu ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
