Scope

This standard specifies the technical requirements, preparation, and identification methods for standard samples used in indirect testing of pendulum impact testing machines according to GB/T 3808.
The notch samples described in this standard and their nominal dimensions are stricter than the sample tolerances specified in GB/T 229.
This standard applies to standard samples used in indirect testing of pendulum impact testing machines according to GB/T 3808.
Note 1: The chemical composition and/or heat treatment of the samples vary depending on their expected energy level.
Note 2: This standard also describes the pendulum standard impact testing machines used for verifying standard samples.
