试验的目的（行程方向弯曲、横向弯曲、工作深度和土壤贯入角的变化、永久变形、疲劳）是给出可重复的结果，以比较S型齿的质量。适用于ISO 5678中规定的S型齿；该测试方法也可用于测试其他类似产品。

The aim of the test (bending in direction of travel, lateral bending, variation in working depth and in soil penetration angle, permanent deformation, fatigue) is to give reproducible results to compare the quality of S-tines. Applies to S-tines as specified in ISO 5678; the test method can also be used to test other similar products.
