So far, I have never had a burst disk blow, so this is all new to me. Bound to happen eventually.
I should have worded my question differently. I used 7500 as an example because burst disks on some PCP equipment go that high. Ignoring specific psi numbers for a moment, since burst disks are made to fail at a higher pressure than the "working" pressure of the system, but at a manufacturers specified level that we assume is below a pressure level that would cause damage to the equipment or an explosion, how do you test a DIY burst disk that has a specification for the gun / tank / compressor, that exceeds the max pressure you can achieve with your tank or compressor?
Example for a burst disk on an airgun.
310 Bar / 4500 PSI max working pressure compressor
6500 psi burst disk for the airgun as specified by the factory
You will need to reach at least 6500 PSI to test the DIY or unknown strength burst disk. How would someone do that if their compressor only goes to 4500 PSI?

Both of my compressors came with a handful of burst disk replacements. They are the metal disk type that you put underneath the burst disk fitting like in this video. No markings. One set is brass, the other is aluminum.
I am guessing that the burst disks on airguns may or may not use that type of burst disk. I am seeing several styles on Amazon etc. It looks to me like having several spares on hand that fit every gun / tank / compressor I own would be a good idea. The thought of having wait for replacements is very troubling!
