Writing a procedure to pressure test a bunch of tubes has got to be the most boring thing ever. Connect tank to adapter. Connect adapter to tube. Turn tank on until gauge reads 40 psi. Turn tank off. Wait five minutes. Write down the number. Subtract number from 40 psi. Write down delta.
You can not put rinse and repeat in a technical document.
I lied. I think reading this might be the most boring thing ever.
