F.12:9.2 - Furnace temperature band
The promise content states [720,740] °C during the soak phase. The delivery Work is the actual batch soak occurrence. Calibrated thermocouple observations either measure the product characteristic directly or use a separately defined sensor-location indicator relation. Evaluation Work applies the band rule and binds its result. An out-of-band result can support RequirementStatus=Violated; insufficient spatial evidence supports EvidenceStatus=Inconclusive and leaves the requirement pending unless the declared acceptance scale specifies another local result.
