Tolerance公差
Tolerance is the allowable variation around a nominal dimension, geometric feature, or process parameter, typically expressed as upper and lower limits or a plus/minus band. It appears on engineering drawings, inspection plans, first-article reports, and process capability studies, where translators must preserve units, sign conventions, and the distinction between unilateral and bilateral limits because a wrong value can make a conforming part appear defective or vice versa.

Where this term appears
In localization work, tolerance appears in engineering drawings, inspection checklists, quality manuals, and first-article inspection reports. It often occurs in dimension tables, notes such as “±0.1 mm,” fit designations, and process capability data. Translators must handle it consistently across drawing notes and body text, especially when source language uses abbreviations for geometric tolerances or references to general tolerance standards.
Translation checks
A frequent error is translating “tolerance” as a vague “allowance” or “margin,” losing the specified upper and lower limits. Another is dropping or swapping plus/minus signs, decimal places, or unit conversions when copying values into translated inspection documents. These errors matter because a shifted limit can make a conforming part appear out of spec or hide a nonconformance, which has direct quality and assembly consequences.
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.
