Hello friend's,

I'm new in this forum and i'm from Portugal. At this moment i'm working in ISO TS but my company don't have the certificate yet.
I have a question, How can i calculate the PPM's from a rold wire supllier?
Explain what is PPM's in the automotive industry.
My English is normal, sorry any mistakes.

Regards to everyone

Hi guerra484

welcome to the Cove. There is a lot of automotive experience here so I'm bumping your thread and seeing what I have to add...

can you give us more description of the rolled wire? about how many meters per roll perhaps.

I'm not an automotive guy but made roll product in the form of tape in the past. In the tape world our PPM measurement would have come from defective rolls.
I can imagine, however, that on a very large roll you might calculate PPM by the meter if the material is used by the meter.
It think the best bet is to contact a customer, or potential customer, and ask what they expect.

Thanks ScottK.
I work with rold wire with 2.5 tuns. We receive for a example a full truck with 10 steel rollers from a supllier and one roll have a problem, the supplier will have a lower rating because the problem and i need to know how i can calculate the PPM's. We only work with tuns, not metters, it is impossible!
I want to have a PPM's goal.
