Hi All,
Can someone help with a formula for calculation of PPM (parts per million) ?
Thanks.

A defective part may have more than 1 defect. So if you seek defective PPM then it amounts to total defective parts in a million. Likewise for defect PPM, where each defect type is accounted.I understand PPM
my question from a customer's stand point
=============
if I get 100 parts in and sort them and there are 15 bad, 85 good. Do i count it as 100 Non - conforming or 15.
Does the above differ if i can sort on line w/ out slowing line down (i.e. look for missing red handle on parts)?
or If my people have to take all parts off line and measure with pair of calipers? or if I have to hire a 3rd party (which i am going to bill the supplier) to sort through parts.
what if supplier (or supplier hired 3rd party) comes in and sorts all parts in my factory
All suspect parts are counted or just the bad ones they find?
==================
Get 100 parts in
5 have Defect A wrong on them
7 have Defect B
8 have defect A & B
20 defective or 27 defective (12 w/ defect A + 15 with defect B)
==============================
What is everyone's expectations &/or history with these issues?
