What standards and specifications are used to select the pressure gauges for the inlet and outlet of a pump?

As the title suggests, are there any mandatory or recommended standards? Please ignore those related to special equipment.
Is this also supposed to meet standards? You just need to specify the manufacturer; small manufacturers’ claims about standards are meaningless. Some of the better domestic manufacturers include Beijing Brady, Dalian Meitian, Chuanyi, and Shangyi. The pressure gauges should be vibration-resistant and made of stainless steel, with a dial diameter of at least 100 mm. These are the basic requirements; if you want a protective case, you can get one as well~
Thank you; maybe I didn’t express myself clearly, and there was some ambiguity. I’m talking about the selection criteria for pressure gauges, such as the range.
The maximum operating value of the instrument should be between 60% and 80% of its capacity
It’s a standard, **, industry-related thing, not a specific value
