【Abstract】By analyzing the failure mechanism of iot gas meter used by urban residents,the Arrhenius model of accelerated life test was determined.A qualitative evaluation method of accelerated life test based on temperature stress is proposed to evaluate whether the gas meter of Internet of Things for urban residents using natural gas can reach the service life of 10 years.The proposed method is used to evaluate the service life of a certain type of iot gas meter,and the test results show that this type of iot gas has a service life of 10 years.
