Test Method: SATRA TM6

Water absorption and desorption - total immersion method

March 1993

SCOPE

This method is intended to determine the rate at which a material absorbs and desorbs water. The method is mainly applicable to fibreboard footwear insole materials but can be used with any type of sheet material.

PRINCIPLE

Method 1 – Absorption per unit area

The mass of water absorbed by a test specimen, with sealed edges, after it has been fully immersed in water for set times is divided by the surface area of the test specimen.

Method 2 – Absorption and desorption

The mass of water absorbed by a test specimen, without sealed edges, after it has been fully immersed in water for a set time is divided by the original mass of the test specimen. The mass of the test specimen is measured again after a period of storage in a standard atmosphere.
