关于压力式温度计检定规程温度微动开关问题的商榷

Discussion on Questions of Temperature Micro Switch in the Verification Regulation of Pressure Thermometer

对JJG310-2002《压力式温度计检定规程》中温度微动开关设定点误差和切换误差进行阐述,通过举例计算和与多部规范比照的方法,说明本规程在设定点误差合格取值范围和切换误差准确度定义上存在两方面值得商榷之处,以期达到对本规程准确理解和正确执行的目的。

The set point error and switching error of temperature micro switch in the verification regulation of JJG310-2002〈Pressure thermometer〉 are described. Based on the calculation of examples and comparison with several regulations, it is pointed out that there are two unreasonable points in the verification regulation： the qualified value range of the set point error and the accuracy definition of the switch error. The purpose is the right understanding and executing of the verification regulation.
