Im sure it can happen occasionally, but dude, it looks like you have either shit ton of bad luck, or you guys are doin something wrong.

Ive never heard of, seen, or read about a cracked gen xtal during a 3bar pressure test.
Im getting sus here.

Doesn't seem right does it.

3 Bar is nothing, especially for a gen xtal - there must've been an inherent fault in it to crack, pressurising at 3 bar wouldn't have done that.

It depends on how the crack happened. If the crystal came flying off during a vacuum pressure test, or during the decompression cycle of a 3 bar test, there’s more than enough energy in a 3 bar gauge pressure difference to send the crystal flying really fast into the hard metal edges inside the machine.
