What this decision changes
How to ask for evidence that temperature sensing remains reliable after heat, cycling and time. In a B2B oven programme, temperature sensor drift is not a component-level detail: it can change the product brief, supplier comparison, certification pathway, field-service exposure and the evidence a buyer needs before release.
Make the measurement comparable
Review sensor specification, calibration method, mounting stress, high-temperature exposure and drift checks before and after endurance tests. Record the unit revision, target market, supply condition, ambient environment, operating mode and sample count. Compare results only when the same method is used for each candidate, and retain the raw record rather than relying on a presentation summary.
Read the result in context
A small drift can shift cooking results, trigger unnecessary thermal cut-outs or conceal an over-temperature condition when tolerances stack up. A useful review links the measured result to the actual consumer use case, not simply to a favourable bench condition. Where results are close to a limit, repeat the test on additional production-representative units and account for normal component variation.
Turn evidence into a purchasing control
Set a drift limit, test interval and corrective-action rule that reflects the control architecture and intended product life. Add the result to the sample-approval file, identify the document owner and require review before any related material, process or supplier change. Component specifications are a starting point; finished-product validation is needed to account for actual mounting and thermal behavior.
