SUMMARY
A hydrostatic test is required for pressure vessels when head pressure is released, as outlined by OSHA regulations and ASTM standards. In the context of a 3000 psi operating system using pressurized nitrogen, the five-year hydrostatic testing requirement can be waived if the head pressure remains intact. However, once the head pressure is removed, a hydrostatic test must be conducted before refilling the vessel. Compliance with local building codes and industry specifications is essential for safety and regulatory adherence.
PREREQUISITES- Understanding of hydrostatic testing procedures
- Familiarity with OSHA regulations regarding pressure vessels
- Knowledge of ASTM standards for pressure vessel testing
- Awareness of local building codes related to pressure systems
- Research OSHA guidelines on pressure vessel testing requirements
- Study ASTM standards relevant to hydrostatic testing
- Explore local building codes that govern pressure systems
- Learn about the implications of head pressure in pressure vessel safety
Engineers, safety officers, and maintenance personnel involved in the operation and testing of pressure vessels, particularly in industries governed by OSHA regulations.

Welcome to PF.
Could you please add more context to your question? What kind of system? What kind of pressure ranges? Is the fluid water or something else?
The more details you can give us, the better we can help you.

WOW so cool thank you for being there..........
In the past....using pressurized N2 on a 3000psi operating system, in a steel flask...the 5 year requirement to hydrostatic test the bottle could be ignored if the head pressure remained on the bottle. once the head pressure was let off the hydro is now require before refill..???
where do i go to find these requirements...Jack

Ah, that kind of hydro test. 
It depends on what regulations apply to your installation. Are you covered by OSHA in the US? Are you at a company or a university, and do they have a Health and Safety Department?

If this is in the US, pressure vessel testing requirements are specified in ASTM and local building codes.
