Description of BS EN IEC 60730-2-9:2019+A1:2019 2019

Replacement:

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

This standard is applicable to automatic electrical temperature sensing controls forming part of a building automation control system within the scope of ISO 16484 .

This standard also applies to automatic electrical temperature sensing controls for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications.

This standard does not apply to automatic electrical temperature sensing controls intended exclusively for industrial process applications, unless explicitly mentioned in the relevant equipment standard.

1.1.1 Replacement:

This standard applies to the inherent safety, to the operating values, operating times, and operating sequences where such are associated with equipment safety, and to the testing of automatic electrical temperature sensing control devices used in, or in association with, equipment.

This standard is also applicable to the functional safety of low complexity safety-related temperature sensing controls and systems.

1.1.2 Addition:

This standard also applies to the electrical safety of temperature sensing controls with nonelectrical outputs such as refrigerant flow and gas controls.

1.1.3 Not applicable.

1.1.4 Replacement:

This standard applies to manual controls when such are electrically and/or mechanically integral with automatic temperature sensing controls.

1.1.5 Replacement:

This standard applies to a.c. or d.c. powered temperature sensing controls with a rated voltage not exceeding 690 V a.c. or 600 9 V.c.

1.1.6 Replacement:

This standard does not take into account the response value of an automatic action of a temperature sensing control, if such a response value is dependent upon the method of mounting it in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer shall apply.

1.1.7 Replacement:

This standard applies also to temperature sensing controls incorporating electronic devices, requirements for which are contained in Annex H and to temperature sensing controls using NTC thermistors or PTC thermistors, requirements for which are contained in Annex J.

Additional subclause:

1.1.101 This standard applies to single operation devices as defined in this standard.
