I'm reasonably sure that the tank chemistry specs did not come from the supplier. That is that they were not written up for not following their own spec, but rather a required spec.
Next time I visit that shop I will find out.

You may need to wait for a long time (and I'm sure you know that) if you expect me to be able to pull the plating spec out of my hat. I only have access to them when I'm on site where the plating specs are used.
I'm not sure what you mean by the ship welding analogy. I don't see where I have excluded that as a method of control. Perhaps you are concerned that I'm suggesting that certifying the welder is the only control ever needed under any circumstance. I do not believe that. At different times any or all of 7.5.2 a-c may apply.
And what on earth does this conversation about validation of processes have to do with the process approach?
- This all (re)started with Steve’s post here when he was asking whether internal auditors should follow the process and check to see if people are following what the process says they should be doing.
- John Broomfield replied saying that they shouldn’t - here
- My first post on the subject was challenging the idea that there is not a requirement for people to follow procedures and in particular John's statement: ‘Management may say "ISO 9001 says that you must obey our procedures" but that has been untrue since the year 2000.’
- You entered into discussion with John Broomfield (who I had refused to debate with by this time) on the subject of process validation - here.
- and my response just followed your thread - here
I hope this helps.
