THIS IS FOR: PVHO Designers, Engineers & Fabricators
If you are designing windows, pressure vessels, chambers of any form of modern pressure vessel which is used with human occupancy inside or in the vicinity, this is an essential engineering document to read, understand and follow its guidance. ASME PVHO-1 is the Safety Standard for designers and fabricators. Knowledge of this standard is not optional. It is the only true guidance the engineering world has to maintain safety in a wide range of space, navy, land, medical and subsea applications, especially when it relates to transparent pressure boundary elements, commonly known as windows. There is a lot to know and there are many professionals able to help guide the full understanding of its content, but it is an essential reference document on the shelf.

OVERVIEW
ASME PVHO-1-2019
Safety Standard For Pressure Vessels For Human Occupancy
This Standard provides requirements for the design, fabrication, inspection, testing, marking, and stamping of pressure vessels for human occupancy, having an internal or external pressure differential exceeding 2 psi. This Standard also provides requirements for the design, fabrication, inspection, testing, cleaning, and certification of piping systems for PVHOs. A PVHO is a pressure vessel that encloses a human being within its pressure boundary while it is under internal or external pressure that exceeds a 2 psi differential pressure. PVHOs include, but are not limited to, submersibles, diving bells, personnel transfer capsules, decompression chambers, recompression chambers, hyperbaric chambers, high altitude chambers, and medical hyperbaric oxygenation facilities. This does not include nuclear reactor containments, pressurized airplane and aerospace vehicle cabins, and caissons.
