Test Method: SATRA TM171

Resistance to water penetration - penetrometer test

April 2017

SCOPE

This method is intended to determine the resistance of a material to water penetration on flexing. The method is mainly applicable to leather but can be used with any flexible sheet material.

PRINCIPLE

A rectangular test specimen is bent partly round, and secured between, two solid cylindrical clamps so as to form a trough. The trough is then immersed in water and the clamps oscillated at a constant speed so that the specimen is repeatedly flexed. The time taken for water penetration through the test specimen to occur is recorded. The mass of water absorbed by, and transmitted through, the test specimen can also be measured.
