Papier et carton — Détermination de la perméabilité à l'air (plage de valeurs moyennes) — Partie 6: Méthode Oken

ISO 5636-6:2015 specifies the Oken method for determining the air permeance and air resistance of paper and board. There is no limitation on the measuring range of air permeance or air resistance of papers and boards. It is unsuitable for rough-surfaced materials, which cannot be securely clamped to avoid leakage.
