IEC 60730-1:2010 applies to automatic electrical controls for use in, on, or in association with equipment for household and similar use, including 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 also 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 control devices used in, or in association with, household or similar equipment. This standard is also applicable to controls for appliances within the scope of IEC 60335-1 as well as controls for building automation systems within the scope of ISO 16484-2. The principal changes in this edition as compared to the previous edition are as follows:- changes to the low temperature test requirements for in-line cords;- revision to the pollution degree for the environment surronding contacts;- addition of the use of screwless terminals on printed circuit boards and revisions to creepage distances;- additions of CISPR 11 EMC requirements;- incorporation of EMC test levels from IEC 60335 series;- additional testing for flexible cords;- revisions to the requirements for resistance to heat, fire and tracking including replacement of clause 21 and Annexes F and G;- new Annex T for additional requirements for non-SELV supplied sensor cable or cord;- new requirements in H.27.1 for first and second fault approach to ensure functional safety;- incorporation of software techniques from IEC 61508-3 in H.11.12;- replacement of Annex D (Canada and USA) with reference to UL 746C;- updates to the references and bibliography;- the keyword index was deleted.
IEC 60730-1:2013 applies to automatic electrical controls for use in, on, or in association with equipment for household and similar use. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof. This standard is applicable to controls for building automation within the scope of ISO 16484. This standard also applies to automatic electrical 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 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. This standard is also applicable to relays when used as controls for IEC 60335 appliances. Additional requirements for the safety and operating values of relays when used as controls for IEC 60335 appliances are contained in Annex U. This standard does not apply to automatic electrical controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. This fifth edition cancels and replaces the fourth edition published in 2010. It constitutes a technical revision. The major changes with respect to the previous edition are as follows: - modification of the title and scope; - revisions to Clause H.26 based on changes in technology, applications, and to improve consistency and layout; - modification to Table H.12 to align with CISPR 22; - revisions to Annex J to correlate the fault modes of thermistors and to exempt thermistors used in conjunction with type 1 controls in SELV low power circuits from the tests specified in Annex J; - new requirements covering battery-powered controls, and the use of batteries in controls; - revision addressing the exclusion of relay faults; - new/updated requirements in Clause 24, for switch mode power supplies; - revisions covering the allowance of screwless-type clamping units complying with IEC 60999-1; - new requirements addressing remotely actuated control functions; - addition of a new/updated leakage current diagram to align the Annex E diagram with the diagram in IEC 60990 and updated requirements for temperature sensing controls.
