Mean Time Between Failures平均无故障时间
Mean Time Between Failures is a reliability metric that expresses the average operating time between one equipment failure and the next under specified operating conditions. In manufacturing documentation, it appears in equipment specifications, maintenance strategy discussions, and reliability reports, where it is often paired with MTTR to estimate expected uptime and plan service intervals.

Where this term appears
Translators encounter MTBF in machine datasheets, preventive maintenance plans, and service-level documents written by equipment suppliers. The term can appear in tables with units such as hours or cycles, and in sentences that specify operating conditions, so translators must keep the conditional nature and not imply a guaranteed failure-free period or warranty.
Translation checks
A common error is translating MTBF as “average service life” or “warranty period,” which misreads a statistical failure interval as the expected lifetime. Another mistake is omitting the conditions under which the value applies; without those, a translated datasheet can overstate reliability and lead to unrealistic maintenance expectations.

Illustrative wording only. Confirm the rendering against the actual source and approved project terminology.
Check the distinction in context
An MTBF figure depends on its stated model or observation basis. Preserve the source unit, population and conditions. Do not translate it as an equipment life guarantee or derive an expected replacement interval from the term alone.
Check the returned Chinese file
Inspect the Chinese reliability note alongside the numerical table. Preserve the stated basis, unit and conditions, and query any source wording that equates the figure with a service-life promise absent from the supplied evidence.
Prepare the connected files
Send the table notes and reliability terminology with the source. Ask the engineering owner to confirm missing assumptions before a Chinese claim is finalized.
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.
