本标准的目的是规定新制造的室内电子纹波控制接收器型式试验的特殊要求，用于接收和解释叠加在配电网电压上的单一音频脉冲，以及执行相应的开关操作。在该系统中，电源频率通常用于同步发射机和接收机。在本标准中，控制频率和编码均未标准化。

The objective of this Standard is to specify particular requirements for the type test of newly manufactured indoor electronic ripple control receivers for the reception and interpretation of pulses of a single audio frequency superimposed on the voltage of the electricity distribution network and for the execution of the corresponding switching operations. In this system the mains frequency is generally used to synchronize the transmitter and receivers. Neither the control frequency nor the encoding are standardized in this Standard.
