Abstract: As the most widely used fire suppression system among fixed fire protection equipment, automatic sprinkler systems face numerous challenges during long-term service due to factors such as geographical and climatic differences, operation and maintenance management, resulting in diverse and unpredictable failure modes. This paper reviews the current state of research on the reliability of automatic sprinkler systems both domestically and internationally, introduces reliability evaluation methods, accelerated testing techniques, and residual life prediction calculation methods, and outlines the development of reliability standard systems worldwide. It points out that while China's reliability standardization system is rapidly advancing, there are still no relevant reliability standards issued for fire protection facilities and equipment. Therefore, based on existing research, this paper proposes recommendations for establishing a reliability standard system for automatic sprinkler systems.

Key words: automatic sprinkler system, reliability, standardization system
