Paper and board - Determination of water absorptiveness - Cobb method (ISO 535:2014)
This International Standard specifies a method of determining the water absorptiveness of sized paper
and board, including corrugated fibreboard, under standard conditions. It may not be suitable for paper
of grammage less than 50 g/m2 or embossed paper. It is not suitable for porous papers such as newsprint
or unsized papers such as blotting paper or other papers having a relatively high water absorptiveness
for which ISO 8787[2] is more suitable.
This method is not intended to be used for precise evaluation of the writing properties of paper although
it does give a general indication of suitability for use with aqueous inks.
