This International Standard specifies requirements for the type test of 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. This standard gives no requirements for constructional details internal to the receiver. This standard does not cover the acceptance tests and the conformity tests. (Nevertheless, an example of what could be an acceptance test is given in annex G (informative).) The reliability aspect also is not covered in this standard as there are no short term procedures available which would fit into type test documents to satisfactorily check this requirement.

Specifies requirements for electronic receivers of single audio frequency pulses superimposed on the mains supply for switching purposes, suitable for outdoor installation. It comprises IEC 1037, Electronic ripple control receivers for tariff and load control, subject to variations for Australian conditions specified in an Appendix.
