The committee responsible for this document is ISO/TC 164, Mechanical testing of metals, Subcommittee SC 2, Ductility testing. This third edition cancels and replaces the second edition (ISO 7438:2005), which has been technically revised. The following changes have been made: — Figure 3 has been revised; — a note has been added in 4.2.2;

This fourth edition cancels and replaces the third edition (ISO 7438:2016), which has been technically revised. The main change compared to the previous edition is the addition of new Annex B , describing bending test at plane strain condition.

符合iso 7438、astm a370或iso 8491标准的弯曲试验是测定金属材料弯曲性能的标准化方法。它支持评估材料的弯曲强度和刚度。 金属材料弯曲试验以3点弯曲试验的形式进行，试验时试样对称地放在两个支座上，并通过压头施加垂直力来产生最大弯曲应力。
