I’ve been working on a device recently, which is an external pressure vessel with a vacuum level of 10 Pa. Can SW6 be used for its verification? How should the design pressure be determined?

Thank you all, guys. I’m just starting out in this industry
This vacuum level is also too low; a thin wall thickness should be sufficient. If verification is required, then the design pressure should be set at 10*10^-6 MPa
The design pressure is taken as -0.1 Ma; the external pressure is primarily considered to account for instability. 、
If there is no relief device, use -0.1; if one is present, use 1.25 times the vacuum level. However, the vacuum level here is too low – only 10 Pa – so it should not fall under the category of pressure vessels; it can be treated as a vessel at normal pressure.
A vacuum degree of 10 Pa means an absolute pressure of 10 Pa, right? !
