Abstract： In temperature measurement technology， contact temperature measurement and non-contact temperature measurement are two common methods.The common temperature measurement methods are thermocouple temperature measurementandinfraredtemperaturemeasurement.Inthelaboratorytestofthefireresistanceofthefredoor，thethermocouple temperaturemeasurement methodisusedfortemperature measurement.This methodmayhave some limitations in practice.On this basis，theinfraredtemperaturemeasurementmethodis introducedtomeasurethesampletemperature inthefireresistance testof the firedoor.This paper mainlyanalyzes the temperature measurement principleand error sourceof thermocouple temperature measurementmethodandinfrared temperaturemeasurementmethod.Throughthecomparison test，diferentmethods areusedtomeasuretheactualfireresistancetesttemperatureofsteeltheralinsulationfiredoor，anditisoncludedthatthe infrared temperature measurement method has certain advantages in this experiment.
