本规范涵盖了电子和通信类设备中使用的电磁密封继电器的一般要求（见6.1）。这些继电器设计用于在从低电平到触点额定值高达5安培交流电（ac）或直流电（dc）的功率切换的全范围内运行。在本文规定的额定负载条件下，基于+125摄氏度的100000次循环，故障率水平被确定为90%的鉴定置信水平和60%的鉴定维持置信水平。注意:使用任何低于额定线圈电压的线圈电压都会影响继电器的工作。注意:拾取、保持和跌落电压仅用于测试目的，不得用作设计标准。 有关其他应用和注意事项的信息，请参见6.1。

This specification covers the general requirements for electromagnetic, hermetically sealed relays for use in electronic and communication-type equipment (see 6.1). These relays are designed to operate over the full range from low level to power switching with contact ratings up to 5 amperes alternating current (ac) or direct current (dc). The failure rate level is established at a confidence level of 90 percent for qualification and 60 percent for maintenance of qualification based on 100,000 cycles at +125 Degrees C under the rated load conditions specified herein. CAUTION: The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay. CAUTION: Pick-up, hold, and dropout voltages are for test purposes only and are not to be used as design criteria. For additional application and caution information, see 6.1.
