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.
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.
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.
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.
