本文件规定了硫化橡胶或热塑性橡胶小试样（Delft试样）撕裂强度的测定方法。 注意该方法得出的结果不一定与ISO？中所述方法得出的结果一致34-1，使用裤子、角钢和新月形试件。它优先于ISO34-1当可用材料数量有限时，特别适合测试小型成品。

This document specifies a method for the determination of the tear strength of small test pieces (Delft test pieces) of vulcanized or thermoplastic rubber. NOTE？The method does not necessarily give results agreeing with those given by the method described in ISO？34-1, which uses trouser, angle and crescent test pieces. It is used in preference to ISO？34-1 when the amount of material available is limited, and can be particularly suitable for testing small finished products.
