Is intended for unsized papers such as blotting papers and other papers having a relatively high water absorbency, and is not recommended for materials having a cappillary rise of less than 5 mm, for which tests such as per ISO 535 may be more suitable.
Abstract
Overview
ISO 8787:1986 - Paper and board: Determination of capillary rise (Klemm method) specifies a laboratory procedure to measure the capillary rise (water uptake by capillarity) of highly absorbent, unsized papers and boards (for example, blotting papers). The method suspends vertical strips with their lower ends immersed in water and measures the upward movement of the wetting front after a fixed time. It is not recommended for materials with capillary rise less than 5 mm; for such materials, tests like ISO 535 (Cobb) are more suitable.
Key topics and requirements
- Scope: Intended for unsized, high-absorbency papers and boards; avoid use if capillary rise
