scope:

In general, this part of International Standard IEC 730 applies to energy regulators for use in, on, or in association with equipment for household and similar use, including energy regulators for heating, air conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof.

These energy regulators may be thermally, mechanically or electrically operated. 

This Part 2 applies to the inherent safety, to the operating values, operating times and operating sequence where such are associated with equipment safety, and to the testing of automatic electrical energy regulator devices used in, or in association with, household or similar equipment.

Throughout this Part 2 the word "equipment" means "appliance and equipment"

This Part 2 does not apply to automatic electrical energy regulators designed exclusively for industrial applications.

This Part 2 is also applicable to individual energy regulators utilized as part of a control system or energy regulators which are mechanically integral with multi-functional controls having non-electrical outputs.

This Part 2 applies to manual energy regulators when such are electrically and/or mechanically integral with automatic controls. Requirements for manual switches not forming part of an automatic energy regulator are contained in fEC 1058-1. 1.2

This Part 2 applies to energy regulators with a rated voltage not exceeding 660 V and with a rated current not exceeding 63 A. 

This Part 2 applies also to energy regulators incorporating electronic devices, requirements for which are contained in appendix H
