The actual pressure in the vacuum vessel is -0.1 MPa; how should the test pressure be determined? Is it also calculated at 1.25 times?

The vacuum design manual specifies that the external hydrostatic test pressure should be 0.196 MPa

This GB150 specifies clearly that it is sufficient to follow 4.6.2.3 in GB/T 150.1.

If unsure about this, there is also clause 4.6.1.6 of GB/T150.1

If there are no other external pressures or temperatures affecting the stress, it is 0.125 MPa

Can the test pressure be determined according to the manual? This should be done according to the standards!
