Production part approval process

The Production Part Approval Process (English: Production Part Approval Process (PPAP ) ) is a method of the now 16949 detached by the ISO / TS QS 9000, are sampled at the serial parts. This approach comes from the automotive industry and is being implemented successfully there for years. It 's all about the quality of supplied parts, which means that the parts of the series tools or serial processes must comply with the drawings. In addition to the parts supplied for review, the patterning (English: part submission warrant (PSW ) ) represents a key element in the sampling process In him all the important information is summarized for requirements, tests and documented.

The exact procedure for example when ordering the parts and also the delivery differs from company to company quite strong. The same applies to the time of the sampling. For safety critical parts long before start of series are sampled while other parts arrive until just before the start of production for sampling. Allen sampling is, however, one thing in common: The division by 5 different levels of sampling.

Levels of sampling

  • Level 1: Only the Part Submission Warrant (PSW ) is presented to the customer;
  • Level 2: Part Submission Warrant (PSW ) with product samples and limited supporting data submitted to customer;
  • Level 3: Part Submission Warrant (PSW ) with product samples and complete supporting data submitted to customer;
  • Level 4: Part Submission Warrant (PSW ) and other receivables, as they were defined by the customer;
  • Level 5: Part Submission Warrant (PSW ) with product samples and complete supporting data are available at the production site of the supplier for evaluation available;

When sampling different stages then be determined, which give a statement as to whether the parts meet the demands have to be reworked or even have to be brand new requested. These stages they are again set individually depending on the company.

Basically, there are but the Production Part Approval Process few essential requirements that apply to all companies. This includes a representative production run. This production run must consist of one to eight hours, with a specific production volume of at least 300 consecutive parts ( excerpt from the AIAG - demand (Automotive Industry Action Group) ):
