OK 1st Part

The first good part out of a production process on a workplace or production line is called OK 1st part. The quality requirements for an OK 1st part are defined in an instruction or checklist describing all relevant check items and measurements to be completed and validated. It is necessary to carry out an OK 1st part after a changeover, change of shifts or a restart (e.g. maintenance, no permanent production). The OK 1st part is displayed in a specific place or holder and needs to be replaced for every new run.
