JIS L 1907、JIS P 8141

Use/Good point

This apparatus is suitable to estimate the water absorbability of water absorbent strong fibre products and paper products. Put the under-part of the test sample perpendicularly submerge in water, owing to capillarity, water will automatically rise, measure the rising height after 10 minutes, and read the graduated ruler mark. Textile test standard also called ‘Byreck method’, the paper standard called ‘Klemm method’.
For textile test, the sample’s width should be 25mm, and water temperature is 20±2℃. On the other hand, for paper test, the sample’s width should be 15mm, water temperature is 23±1℃.
This apparatus has no water temperature control function, so before the test, you need to confirm the water temperature.

Remarks

*“PW-5P-AT2”type which can survey the real time sopping height is belong to the same type product.
