Are studs on pipe flanges larger than M36 required to undergo impact and tensile tests?

GB/T 150.4-2011 specifies impact (requiring at least 0°C impact) and tensile requirements for studs larger than M36, whereas the pipe flange standard only requires impact at temperatures below -20°C (and the impact energy requirement is also lower than that specified in GB/T 150.2-2011). How should this requirement be implemented? Previous drawings also did not include any additional requirements for pipe flange studs larger than M36.

For pressure vessels falling within the scope of GB/T150, the stud and nuts of their pipe flanges with a size larger than M36 shall meet the requirements of Clause 6.7 in GB/T150.4-2011.

Only the main studs of the equipment, that is, the heat exchanger tube box, the flat cover of the tube box, and the manhole cover; tube flanges are not included
