Test Method: SATRA TM220

Dynamic water penetration test for leather - Bally permeometer method

August 2000 (2018)

SCOPE

This method is intended to determine the water resistance of sole leathers. The method is applicable to all types of sole leather.

PRINCIPLE

The leather test specimen is wetted on the wearing surface, and is flexed and compressed in a similar manner to the sole of a shoe during walking. The period of flexing which is just sufficient to cause water to penetrate through the test specimen from the grain to the other surface is determined, together with the percentage water absorption by mass and the rate of water penetration through the test specimen during one or more specified time intervals.
