Annotation of standard text ČSN EN ISO 4022 (420776):

Norma specifikuje metodu stanovení propustnosti tekutin u propustných spékaných materiálů, ve kterých je pórovitost záměrně spojitá nebo vzájemně propojená a zkoušení se provádí v takových podmínkách, že propustnost tekutin lze vyjádřit pomocí viskózního a inerciálního součinitele propustnosti. Norma se nepoužívá u velmi dlouhých dutých válcových zkušebních vzorků malého průměru, u kterých pokles tlaku tekutiny při průchodu vnitřním průměrem válce nelze zanedbat ve srovnání s poklesem tlaku tekutiny procházející tloušťkou stěny
