This part of IEC 62052 specifies general requirements for the type test of newly manufactured indoor tariff and load control equipment, like electronic ripple control receivers and time switches that are used to control electrical loads, multi-tariff registers and maximum demand indicator devices.
This standard gives no requirements for constructional details internal to the tariff and load control equipment.
In the case where tariff and load control functionality is integrated into multifunction electricity metering equipment, the relevant parts of this standard apply.
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 F.
The safety aspect is covered by IEC 62052-31:2015.
The dependability aspect is covered by the documents of the IEC 62059 series.
