  • SCOPE

    1 Scope and normative references

    This clause of Part 1 is applicable except as follows:

    1.1 This part of IEC 60730 applies to automatic electrical pressure sensing controls with a minimum gauge pressure rating of -60 kPa and a maximum gauge pressure rating of 4,2 MPa, for use in, on or in association with, equipment for household and similar use that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof, including heating, air-conditioning and similar applications.

    1.1DV Modification of 1.1 of the part 2 by adding the following:

    Conversions: -60 kPa to -8,71 psi and 4,2 MPa to 609,58 psi.

    1.1.1 This standard applies to inherent safety, operating values, operating sequences where such are associated with equipment protection, and to the testing of automatic electrical pressure sensing controls used in, on or in association with, household and similar equipment.

    Throughout this standard, the word "equipment" means "appliance and equipment".

    This standard does not apply to pressure sensing controls intended exclusively for industrial applications.

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

    Automatic electrical pressure sensing 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.

    This standard is also applicable to controls for appliances within the scope of IEC 60335-1.

    See also Annex J.

    1.1.1DV Modification to clarify 1.1.1 of the part 2:

    In IEC terminology, "safety" is defined as an acceptable level of risk. This is consistent with the intention of UL requirements to reduce the risk of fire, electric shock or injury to persons.

    1.1.2 Replacement:

    This standard applies to automatic electrical controls, mechanically or electrically operated, responsive to or controlling a pressure or vacuum.

    1.1.3 Not applicable.

    1.1.4 Replacement:

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

    Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1.

    Addition:

    1.1.101 This standard contains requirements for electrical features of pressure sensing controls and requirements for mechanical features that affect their intended operation.

    NOTE Subclause 18.101 as it pertains to gas and/or oil controls, is under consideration pending review or revision by ISO/TC 109 and ISO/TC 161.

    1.1.102 In general, these pressure sensing controls are integrated or incorporated with the equipment or are intended to be integrated in, or on the equipment. This standard also covers these controls when they are independently mounted. In-line cord controls are not covered by this standard.

    1.4 Replacement:

    This standard applies also to pressure sensing controls incorporating electronic devices, requirements for which are contained in Annex h.

    This standard applies also to pressure sensing controls using NTC or PTC thermistors, requirements for which are contained in Annex J.
