ZHTest Method: SATRA TM149
Strength of eyelet facings and other laced fastenings
December 2021
SCOPE
This method is intended to determine the strength of a footwear fastening when it is subjected to a force applied by a lace in the same manner as in wear. It is applicable to any type of footwear fastening that involves the use of a lace. It can also be used for assessing the strength of other pull-up tabs and loops normally pulled by hand, such as loops at the rear of the topline used to aid donning of the footwear.
PRINCIPLE
A test specimen, which includes the fastening, pull-up tab or loop, is cut from an item of footwear. The test specimen is clamped in one jaw of a tensile testing machine; a length of lace is inserted through the fastening and both ends clamped in the second jaw. The force required to cause failure of the fastening is measured and the type of failure is recorded.
