Uptime is the percentage of planned production time during which a piece of equipment or a line is actually operating and available for work, rather than stopped for failure, setup, or idling. In manufacturing documentation it appears in overall equipment effectiveness (OEE) reports, maintenance dashboards, service contracts, and capacity planning, where translators must distinguish scheduled uptime from total calendar time.
Uptime typically appears in translated maintenance manuals, OEE dashboards, service-level metrics, and production reports. Translators handle it in KPI tables, shift summaries, and troubleshooting guides, where it accompanies figures, formulas, and targets. Terminology work often involves clarifying the exact denominator—planned time, calendar time, or shift time—so the translated metric does not shift meaning.
A frequent mistranslation is rendering “uptime” as “availability” or as total running time without checking whether the source denominator is planned production time, calendar time, or shift time. That causes real confusion in OEE and service-level texts, where availability and reliability may be separate KPIs. Another error is literal “up time” splitting or using “正常运行时间” in contexts that imply runtime only, losing the scheduled-time ratio.
The EU Machinery Directive requires documentation in the language of the destination market. Safety-related terms must map exactly to the wording of the governing standard.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
