ZHTest Method: SATRA TM375
Whole boot flex and water resistance tests for wellington boots
June 2010
SCOPE
This method provides procedures for assessing a whole wellington boot for a) the resistance of the upper and foxing to cracking or other types of failure during repeated flexing b) the water resistance during repeated flexing. The method is applicable to all wellington boots except for those below UK children’s size 11.
PRINCIPLE
The boot is repeatedly flexed through a specified angle about a defined flexing line by a test machine. When water resistance is being assessed, the boot is held in a trough of water while being flexed. After a predetermined number of flexes the boot is examined, either for signs of upper and foxing damage or water penetration, depending upon whether the resistance to damage or water resistance is being assessed. The number of flexes to which the boot is subjected and the angle through which it is flexed are determined by the property being assessed and whether the boot is a children’s or adult size.
