- Scope
- This International Standard specifies requirements for the type test of newly manufactured indoor time switches with operation reserve that are used to control electrical loads,multi-tariff registers and maximum demand devices at certain days and hours throughout the year. These time switches may employ various types of operation including the use of electronic circuits.This Standard does not apply to time switches operated by remote control or synchronized by radio-frequency. This Standard includes time switches with analogue dials or digital display that are: - synchronous; - crystal-controlled. 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 D.) The reliability aspect is not covered either in this atandard as there are no short term procedures available which would fit into type test documents to check these requirements satisfactorily.
