Test Method: SATRA TM77

Flexing machine - water penetration test

April 2017

SCOPE

This method is intended to assess the resistance to water penetration of completed footwear during flexing. The method is applicable to most types of footwear.

PRINCIPLE

The footwear specimen is placed in a tray of water and is repeatedly flexed about its natural flexing line by a machine. After a predetermined time or number of flexes the footwear is subjectively assessed for signs of water penetration. The level of the water in the tray, the number of flexes or the time between assessments, and the angle through which the footwear is flexed, are all determined by the type of footwear being tested.
