D256 Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics 塑料及电绝缘材料的抗冲击性的测试方法
Izod is a person who developed this test method (similar to Rockwell who developed the Rockwell Hardness Test 洛氏硬度测试方法)
I believe that there may be corresponding GB equivalent to “Test Method A—Reversed Notch Izod”, then you may refer to that GB; or alternatively, upload the details of “Test Method A—Reversed Notch Izod” for our discussion to find out a proper translation.
