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.
Abstract
Overview
EN ISO 535:2023 (ISO 535:2023) specifies the Cobb method for determining the water absorptiveness of paper and board - including corrugated fibreboard - under standard laboratory conditions. The method measures the mass of water absorbed by a defined test area and expresses the result as a Cobb value (grams per square metre, g/m²). This edition, adopted by CEN in 2023, supersedes EN ISO 535:2014.
