24-PH3 Testing of Cylinders
The topic talks about cylinders and also bulk hazardous material tanks, is there a preferred target storage vessel size? Are we supposed to focus on solutions for DOT Cylinders like K bottles or T Bottles, or is the focus on Tube trailers like a CNG-1 (Type-2) tube traileror a DOT-105/112 tank car?
The Topic mentions hydrogen cylinders, is the focus on Liquid Hydrogen transport and delivery at ambient or cryo-compressed at <600 PSI? Is the expectation that this is targeted at vacuum jacketed cylinders or are we looking at foam insulated tanks? If it's foam insulated will we be able to mechanically remove foam to access the tank, or will it have to remain undisturbed? Will the test method have to survive direct contact with LH, or can we conduct tests from the outside surface?
Will solutions have to be "Completely Integrated" to the cylinder and not require the inspector to bring tools/instruments, or can we assume field portable instrumentation to measure changes in physical property?
Is the approach able to take a data-driven process where we look for trend information and slow changes to physical parameter or is the aim to look for a simple GO/NOGO indication?

The Focus should be on smaller Pressure vessels and look at the standards found in CFR 49 173.302, 173.314, 178 and 180. the target is any cylinder with the hopes of expanding application. The Offeror should plan to test a cylinder type of their choice that is best reflective of their capabilities. The end result should lead to a product that the user is able to determine if the cylinder is fit for use at any time.
