这主要用于评估上部材料形成褶皱或***的趋势，这些褶皱或***是在持续操作期间出现的，尤其是在脚趾和座椅区域周围。它特别适用于测试容易出现这种问题的合成上材料。上材料的条带被夹在两个夹钳之间。它们按预定的数量聚集在一起，以对应缩短。然后按下有机玻璃条，检查材料是否有褶皱或***。缩短的程度逐渐增加，直到出现不可接受的***。
符合以下标准进行试验：Satra TM44 BS 5131:3.4
This is mainly used to assess the tendency of upper materials to form pleats or wrinkles where ‘shortening’ occurs during the lasting operation, particularly around the toe and seat areas. It is particularly useful for testing synthetic upper materials which are prone to this problem.A strip of upper material is held between two clamps.They are brought together by a predetermined amount to correspond to the shortening. A perspex bar is then pressed down and the material can be checked for folds or wrinkles.The degree of shortening is increased progressively until unacceptable wrinkles occur.
The STD 119 can be used to carry out tests to the following standa***:
