To address the inefficiency and resource constraints of reliability verification tests for multi-model electricity meters in high dry-heat environments, this study proposes a sequential test scheme integrating time-varying acceleration effects and dynamic withdrawal mechanisms. Based on the Weibull distribution, an accelerated sampling characteristic function for reliability life indicators is constructed. A time-equivalent model is employed to map time-varying stress test data to reference conditions, establishing a sequential probability ratio test (SPRT) framework. A successive withdrawal-based multi-model synchronous verification mechanism is designed, dynamically eliminating adjudicated types and updating test criteria to achieve parallel verification of multi-model meters under limited test slots. This research provides an efficient and precise solution for collaborative reliability verification of multi-model electronic products in typical environments.
