One third of the total audit days on manufacturing (TS 16949)


Quite Involved in Discussions
In the clause 5.3c) in the Rules 4th, it says: The min. audit time in manufacturing process shall be a min. of one third of the total audit days.

Situation: a site with 5.5 md, but it has two RLs which are allocated as 1md (0.5md for each RL), so the total audit days on the site will be 4.5md. Which one is the correct calculation ?
5.5md/3 = 1.83md = 14H40min
4.5md/3 = 1.50md = 12H

Good day Jelly,

Are these remote locations to be covered in the same audit? If so, my understanding is they will be included in the total audit time.

Thus, 5.5md/3 = 1.83md = 14H40min

Yes these RLs are covered in the same audit.
If your answer is correct, or it is the intent of IATF, then it would be inconvenience to allocate the audit time to other processes.
I was heard a lot of complains about this requriement.
For example, what shall I audit, if the client does only one job, stamping, with such long time 14H40min ?
