What pressure limits can computer equipment withstand?

Question

Share your experience.
Premises for server rooms and operator rooms were designed, in which gas fire extinguishing (AUGP) is provided.
The premises do not provide for permanently open openings for pressure relief, as required by SP 5.12120.2009 (clause 8.14.2).
The customer requires "Confirm that the equipment located in the premises protected by the AUGP installations is designed for a pressure increase of up to 5 kPa."
The question is, where can I find information on limiting pressure drops for conventional equipment?
How to justify the answer to the customer?
Thank you!

Answer 1

Hypothetically, hard drives can suffer, but they are harmed by a drop in pressure, not an increase.
5 kPa is approximately 0.04 atmospheres or 37 millimeters of mercury.
At what rate is the pressure increasing?
