Requirements for impact tests in GB/T13401-2017

Regarding the impact test specified in 7.1.3.1 of GB/T13401-2017, do fittings with material grades CF415K and CF485K need to undergo an impact test regardless of their diameter or wall thickness?

Those that cannot produce impact specimens cannot conduct impact tests.

Under the new standard, the minimum size of the test samples is now 10×2.5 MM. . . .

Taking steel pipes as an example, only a 25×3.5 steel pipe can be used to produce a 10×2.5 impact specimen. Elbows of the same size cannot be used to produce 10×2.5 impact specimens. You can draw a diagram to give it a try.

What does CF415k mean?

It is equivalent to the 20# steel specified in the former GB9948 standard, or asme A106; the suffix letter K indicates that an impact test is required

What does the ‘s’ in CF415-S mean?
