Julie, A level 2 PPAP requires more supporting data from the customer than a level 1, but it does not cover all on the list of 18 potential requirements. A level 2 PPAP would require design records for saleable items, as well as all additional components and information. Dimensional results, materials and performance test findings, as well as qualified laboratory paperwork, would also be required. As you can see, the amount of information rises as the levels go. It is also at this level that a sample product must be supplied to the client rather than being retained by the provider.
