GB/T 18658-2018 Charpy V-notch reference test pieces for indirect verification of pendulum impact testing machines
Abstract
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.
