Tire pressure monitoring system quality inspection report GB T26149 standard test report.
1. Overview. A tire pressure monitoring system (TPMS) is a device used to monitor tire pressure and temperature, which helps to improve driving safety and extend tire life by providing tire pressure and temperature information to the driver. In order to ensure that the quality and performance of the TPMS system meets the relevant standards, the TPMS needs to be inspected and evaluated for quality. The GB T26149 standard is a national standard in China's automotive industry, which stipulates the technical requirements, test methods, and inspection rules of tire pressure monitoring systems.
