CENTERED MANUFACTURING. Centered manufacturing should be the goal for controllable characteristics (process control). For special characteristics, a controlled and capable process shall be followed and documented, with continuous, systematic analyses of test results by means of statistical process control (SPC) in accordance with the rules and regulations. In the case of test processes for which no capability could be verified for its associated manufacturing processes and for non-controllable test criteria, such as tool-specific characteristics, the supplier may only utilize the tolerance reduced by the amount of measurement uncertainty. For characteristics limited on both sides, the measurement uncertainty must be deducted at both tolerance limits. In the case of non-process-capable “special characteristics,” 100% inspection must also be documented through statistical methods.
