What is the understanding regarding \"for pipes with a large pressure difference, the static pressure of the test medium should be included in the test pressure\"?

1. Source: GB 50235-2010 \"Code for Construction of Industrial Metal Piping Projects\", P52, 8.6.4-9. 2. Question: What is the understanding regarding the statement that \"for pipes with a large alignment difference, the static pressure of the testing medium should be included in the testing pressure\"? Does this sentence mean that for pipes with a large pressure difference, the design pressure and design temperature should be determined based on the conditions at the lowest point, and then the test pressure should be calculated using formula (8.6.4 on page P51 of this standard)? How should it be understood then? I would like to seek advice from those with extensive experience; thank you in advance! ! !
In other words, the test pressure must include the static pressure generated by the height difference
Especially during verification, the experimental pressure of the pipeline design must meet the experimental requirements

During strength testing, media such as water are used; if the pressure at lower locations is taken as the standard, then the pressure at higher locations will not reach the required testing strength. However, it is necessary to ensure that the pressure in lower areas does not exceed the maximum allowable circumferential stress value of the pipeline.
