CAN/CSA E60730-2-9-01 (R2011) Historical

This part of IEC 60730 applies to automatic electrical temperature sensing controls for use in, on or in association with equipment for household and similar use, including electrical controls for heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil, soild fuel, solar thermal energy, etc., or a combination thereof.

This part 2-9 applies to automatic electric controls using NTC or PTC thermistors, additional requirements for which are contained in annex J.

1.1.1 This part 2-9 applies to inherent safety and to operating values, operating times and operating sequences where such are associated with equipment safety. It applies also to the testing of automatic electrical control devices used in, or in association with, household or similar appliances.

Examples of such controls include boiler thermostats, fan controls, temperature limiters and thermal cut-outs.

This part 2-9 does not apply to automatic electrical controls designed exclusively for industrial applications.

This part 2-9 is also applicable to individual controls utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs.

Automatic electrical controls for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

1.1.2 This part 2-9 also applies to the electrical safety of temperature sensing controls with non-electrical outputs such as refrigerant flow and gas controls.

1.1.3 This part 2-9 is also applicable to controls for appliances within the scope of IEC 60335. See more
