Is a 60-cubic-liter LNG storage tank with a design pressure of 1.45 MPa required to have A2-grade pressure vessel design qualifications?

I’m facing an issue while applying for a design renewal certificate, and I’d like to ask everyone for advice! Thank you!
It does not fall under Category III pressure vessels, and therefore no A2-level pressure vessel design qualification is required...
This container belongs to Category II pressure vessels; why is a Class A2 pressure vessel design qualification required?
The design permission regulations specify that pressure vessels of medium and low pressure, Category 3, are classified as Class A2. Does this Category 3 refer to Category III in the 99th edition of the pressure vessel regulations or in TSG21-2016?
According to the 1999 regulatory standards, it belongs to Category III.
The tolerance specifications have already reached the 2016 version; what’s the point of talking about the 1999 version anymore?
According to the fixed-volume code or the large-volume code, the PV product does not meet the standards for Class III pressure vessels; therefore, an A2-level pressure vessel design qualification is not required
If the drawing was designed when the old capacity regulations were in effect, use the old regulations; otherwise, use the new ones
