ZHTest Method: SATRA TM120
Strength of attachment of straps and nailed or stapled uppers
June 2021
SCOPE
This test method is intended to determine the strength of attachment of straps, nailed or stapled uppers, to the sole of completed footwear. The method is applicable to all footwear with uppers having straps less than 35 mm wide or uppers attached to the sole by means of nails or staples. The attachment strength of straps of 35 mm or wider should be assessed by measuring their bond strength according to SATRA TM411.
PRINCIPLE
An increasing force is applied to either a strap, or a strip cut from the upper containing one or more nails or staples which connect the upper to the sole, until failure occurs. The force is applied at right angles to the plane of the sole unit. The force at failure of attachment of the straps, or strips of upper, is determined.
