scope:

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. 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. 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. This standard applies to automatic electrical controls, mechanically or electrically operated, responsive to or controlling a pressure or vacuum. This standard applies to manual controls when such are electrically and/or mechanically integral with pressure sensing controls. 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.
