IEC 60730-2-11:2019 is available as IEC 60730-2-11:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60730-2-11:2019 applies to energy regulators for use in, on, or in association with equipment, including energy regulators 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 applies to the inherent safety, to the operating values, operating times and operating sequence where these are associated with equipment safety, and to the testing of automatic electrical energy regulator devices used in, or in association with, equipment. This standard is also applicable to energy regulators for appliances within the scope of IEC 60335-1. Throughout this standard the word “equipment” means “appliance and equipment”. This standard also applies to automatic electrical energy regulators 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 energy regulators designed exclusively for industrial process applications unless explicitly mentioned in the equipment standard. This standard does not apply to equipment that are specifically within the scope of building automation equipment. This standard is also applicable to individual energy regulators utilized as part of a control system or energy regulators which are mechanically integral with multi-functional controls having non-electrical outputs. This standard applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision to the title to remove “for household and similar use”; b) changes to the scope and related modifications; c) changes to definitions in Annex H. This Part 2-11 is intended to be used in conjunction with IEC 60730 1. It was established on the basis of the fifth edition of that standard (2013) including Amendment 1 (2015). Consideration may be given to future editions of, or amendments to, IEC 60730-1. Keywords: Automatic Controls, Energy Regulators, Control Systems
