摘　　要：针对家用燃气报警器用的气体传感器的检定方法,提出了不同于报警器检定的、完全针对传感器本身的特性评价的方案,包括检定用模块的规定、符号的规定等。特别是提出了如何使用传感器输出信号的数据,直接评价传感器的报警性能的方法。在此基础上,提出了如何根据报警器检定标准来评价传感器的合格范围,同时提出了对传感器的响应时间、环境试验、长期稳定性和耐久性等特性的评价方法。At present, the examination methods for gas alarms are used to be substitute ways when the characteristics of gas sensors in alarms are need to be measured. In order to solve this problem, a special systematic solution for testing gas sensors themselves is proposed, which is different from those for gas alarms, including the test module design, the mark stipulation and so on. Specially, it is given how to use the sensor output data to evaluate the performances of alarms directly. Furthermore it is proposed how to determinate the sensors up to standards according to the examination standards of alarms, and the evaluating method of sensor characteristics is also given, such as response time, environmental test, long-term stability, durability and so on.
