Annotation of standard text ÖNORM EN 993-4 :

Diese Norm legt ein Verfahren zur Messung der Gasdurchlässigkeit von dichten geformten feuerfesten Erzeugnissen fest. Da das festgelegte Verfahren die dynamische Viskosität des Gases berücksichtigt, dürfen die erzielten Ergebnisse nicht direkt mit jenen verglichen werden, die mit Hilfe früherer Verfahren, die die Viskosität nicht berücksichtigten, ermittelt wurden.
