This equipment has been made to assess the resistance to water penetration of completed footwear during repeated flexing; this test is applicable to all types of footwear.

During the test the upper part of the shoe is sealed by a rubber collar through which compressed air is passed.
The sample is then immersed in a bath of water to the top and applied an internal pressure of 10kPa for 30 seconds. The sample is visually analyzed to check for formation constant
of air bubbles, which indicate air release.

This machine can be fitted with two stations.
