Control Chart控制图
A control chart is a statistical graph that plots process data over time against a center line and control limits calculated from historical variation. It appears in manufacturing quality procedures, SPC training, and process-monitoring reports where teams use patterns such as shifts, trends, and out-of-limit points to distinguish common-cause variation from special-cause events that require appropriate investigation or corrective action.

Where this term appears
In localization, control chart appears in SPC manuals, quality-system documentation, plant dashboards, and statistical software interface strings. Translators must handle terms such as upper control limit, lower control limit, subgroup, and special cause consistently, because these labels map to chart annotations, alarm rules, and audit criteria in manufacturing software.
Translation checks
A frequent error is translating control limits as 'specification limits' or 'tolerance limits,' or mixing them in the same text. Control limits come from process behavior, while specification limits come from customer requirements; confusing them can make an unstable process appear acceptable or trigger alarms for nonconforming product in translated SPC guidance.
Keep the term aligned across your files
Check equipment names, units, safety instructions and interface labels against the source and approved references. Confirm any market-specific document requirements separately.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
