Test planning. The basis for ensuring the delivery quality is a test concept which stretches across all the process steps. All process steps must be structured in such a way that defects are avoided or if that is not possible, defects are safely detected. The following Q-Gates must be installed from incoming goods to outgoing goods, deviations to it must be consulted with Handtmann supplier management. - accounting and if necessary technical incoming goods inspection - First / last part approval - Inspections during production / SPC - Final inspection - Product audit - Internal audits - Re-qualification, see chapter 6 The Q-Gates must be listed in the production control plan. Product and process features that have a special importance with respect to functionality, safety, lifespan or assembly, are referred to asSpecial features. For the special features, a process capability evidence (standard specifications cmk ≥ 1.67 / cpk ≥ 1.33) is required. This must be determined and monitored using statistical methods. If the process capability cannot be achieved, then the relevant feature must be ensured using a 100%-check. The special features are defined with the respective verification (e.g. PFU) by Handtmann’s development department. These features must be included marked as such in the production control plan. It should be possible to see the verification upon request at any time. Unless agreed otherwise, VDA volume 2 forms the basis for the production process approval and product approval (“sampling”). For a uniform presentation of the PPF-report, the templates shown there must be taken into account. The PPF-report includes all documents required as evidence of customer's requirements (e.g. measurement reports, material tests, process capability analyses…). The PPF-approval is the pre-requisite for delivering supplies to our company. A delivery without (at least conditional) approval is not permitted. A delivery order/delivery schedule alone is not an approval. Deviations in the dimension, material and function must be approved before a sampling by the development department of Handtmann. The deviation approval must be included in the sampling process. The sampling documents must always be sent to xxxx@xxxxxxxxx.xx. Incomplete documents are not acknowledged. Initial samples may be produced only with series equipment, under series process conditions and with the personnel designated for series production. The samples must be taken randomly from a representative series produ...
