Scope

This standard specifies the terms and definitions, principles, samples, testing equipment and instruments, testing steps, evaluation and processing of test results, and test reports for the instrumented Charpy V-notch impact test method of metal materials.
This standard is applicable to the determination of the instrumented Charpy V-notch impact performance of metal materials.
Compared with the GB/T 229 Charpy pendulum impact test method, this standard provides more product-related fracture information than ordinary impact tests. U-notch specimens can also be referenced according to this standard.
For general information on instrumented impact tests, see references [3-8].
