Paper and board - Determination of water absorptiveness - Cobb method (ISO 535:2023)

This document specifies a method for determining the water absorptiveness of paper and board, including corrugated fibreboard, under standard conditions.
This document is not applicable for paper of grammage less than 50 g/m2 or embossed paper. It is not applicable for porous papers such as newsprint or papers such as blotting paper or other papers having a relatively high-water absorptiveness for which ISO 8787 is more suitable.

Papier und Pappe - Bestimmung des Wasserabsorptionsvermögens - Cobb-Verfahren (ISO 535:2023)

Dieses Dokument legt ein Verfahren zur Bestimmung des Wasserabsorptionsvermögens von Papier und Pappe, einschließlich Wellpappe, unter Standardbedingungen fest.
Dieses Dokument ist nicht anwendbar auf Papier mit einer flächenbezogenen Masse von weniger als 50 g/m2 oder für geprägtes Papier. Es gilt nicht für poröses Papier wie Zeitungsdruckpapier oder Papiere wie Löschpapier oder andere Papiere mit einem relativ hohen Wasserabsorptionsvermögen. Hierfür ist ISO 8787 besser geeignet.

Papier et carton - Détermination de la capacité d'absorption d'eau - Méthode de Cobb (ISO 535:2023)

Le présent document spécifie une méthode de détermination de la capacité d’absorption d’eau du papier et du carton, y compris du carton ondulé, dans des conditions normalisées.
Le présent document ne s’applique pas aux types de papiers suivants: papier de grammage inférieur à 50 g/m2, papier gaufré, papiers poreux tels que le papier journal, papiers tels que le papier buvard ou d’autres papiers ayant une capacité d’absorption d’eau relativement élevée, l’ISO 8787 étant mieux adaptée dans ces cas.

Papir, karton in lepenka - Določevanje absorpcije vode - Cobbova metoda (ISO 535:2023)

Ta dokument navaja metodo za določevanje absorpcije vode pri papirju, kartonu in lepenki, vključno z valovitim kartonom, v standardnih pogojih.
Ta dokument se ne uporablja za papir z gramaturo, ki je nižja od 50 g/m2, ali za reliefno pretisnjen papir. Ne uporablja se za porozni papir, kot je časopisni papir ali papir, npr. pivnik ali drugi papirji z relativno visoko absorpcijo vode, za katere je bolj primeren standard ISO 8787.
