GB/T 229-2020 Translated English of Chinese Standard. (GBT 229-2020, GB/T229-2020, GBT229-2020): Metallic materials - Charpy pendulum impact test method [Buy--download True-PDF in 3-second: https://play.google.com/books > Sign in > This BOOK > "3-dots" > Export > Save as "*.pdf"]https://www.chinesestandard.net, 10 ene 2021 - 42 páginas This standard specifies the Charpy pendulum impact test method for measuring the energy absorbed by impact specimens (V-shaped, U-shaped notch, unnotched specimens) in the impact test of metallic materials. This standard applies to the Charpy pendulum impact test under room temperature, high temperature or low temperature conditions, but does not include the instrumental impact test method, the content of this part is as shown in GB/T 19748. |
