On a different but not unrelated topic, if u want to pressure test a low pressure (10 bar) ram and buffer tank can I just connect it to a compressor an test them up to 15 bar? I would put it in a box or behind a wall or something to protect my self but is that enough?
Does someone have to sign it off (I can't see anyone saying it will be fine in the environment we use it in and open themselves up o a lawsuit if it failed and injured someone). Does this person have to be qualified or just anybody?
