Are motor manufacturing standards universally national standards?

Are motor manufacturing standards universally national standards? What is the standard used for manufacturing generally? Is there a general table available for checking the power and corresponding shaft diameter as well as weight of motors?
Conventional brand motors all comply with national standards; however, it is possible that some cheap, inferior products purchased to save money do not meet these standards. Generally, one can refer to ICE (International Electrotechnical Commission), ISO (International Organization for Standardization), and GB (**standards**). One can also visit the websites of well-known motor manufacturers, where there are sample data sheets for motors, providing information on parameters such as power, shaft diameter, and weight.
The power can be determined, as well as the shaft diameter; however, the weight varies due to differences in the detailed structure of each manufacturer’s products

As mentioned in the third comment, the weight varies depending on the manufacturer； Regarding the shaft diameter, I compared it with that of the shaft used in conjunction with the coupling, and they are the same; I haven’t examined it in detail.
