The following are personal speculation:
The so-called name is not the right words. The special equipment inspection included in the national vocational qualification catalog is to the nationwide special equipment inspection and testing personnel (including inspectors and non-destructive testing personnel) to distinguish between the special inspectors and the difference between the state staff.
It means that special equipment inspection and testing officially become an industry. Further releasing the will to the market and laying the groundwork.
Maybe the test will become harder and the bar will be raised.
