Is a vessel with a design pressure of less than 0.1 MPa considered a pressure-free vessel? Does it belong to pressure vessels?

So, if the design pressure is between -0.5 and 2.7 kPa, does this belong to a pressure vessel at normal pressure? Is it a type of pressure vessel? -Does 0.5 kPa mean negative pressure?

Does anyone know? ? ? Solve! ! !

It does not belong to pressure vessels. -0.5 kPa is negative pressure; 0.1 Mpa = 100 kPa

The classification of pressure vessels should follow national standards.

It does not belong to pressure vessels, but if it is a distillation tower； A safety valve should be installed for a top pressure of 0.03 MPa to 0.1 MPa

Then what does it belong to? A regular atmospheric-pressure container?
