CSA E60730-2-15:24

CSA Preface This is the second edition of CSA E60730-2-15, Automatic electrical controls — Part 2-15: Particular requirements for automatic electrical air flow, water flow and water level sensing controls, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60730-2-15 (third edition, 2017-08). It supersedes the previous edition, published in 2014 as CSA E60730-2-15 (adopted IEC 60730-2-15:2008). For brevity, this Standard will be referred to as "CSA E60730-2-15" throughout. This Standard is intended to be used in conjunction with CSA E60730-1:15, Automatic electrical controls — Part 1: General requirements (adopted IEC 60730-1:2013, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on International Standards, under the jurisdiction of the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This clause of Part 1 is applicable except as follows: 1.1 Scope Replacement: This part of IEC 60730 applies to automatic electrical air flow, water flow and water level sensing controls for use in, or in association with, boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating, air-conditioning and similar applications. NOTE Examples are water flow and water level sensing controls of the float or electrode-sensor type used in boiler applications and air flow, water flow and water level sensing controls for swimming pool pumps, water tank pumps, cooling towers, dishwashers, washing machines, air conditioning chillers and ventilation applications. This document also applies to automatic electrical air flow, water flow and water level 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. 1.1.1 Replacement: This document applies to the inherent safety, to the operating values, operating sequences where such are associated with equipment protection, and to the testing of automatic electrical air flow, water flow and water level sensing controls used in, or in association with, equipment. This document is also applicable to controls for appliances within the scope of IEC 60335-1. Automatic electrical air flow, water flow and water level 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 document. This document 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 document is not applicable to pressure sensing controls, requirements for which are contained in IEC 60730-2-6. This document does not apply to air flow, water flow and water level sensing controls designed exclusively for industrial applications unless explicitly mentioned in the relevant equipment standard. NOTE Throughout this document, the word "equipment" means "appliance and equipment". 1.1.2 Addition: This document applies to automatic electrical controls, mechanically or electrically operated, responsive to or controlling air flow, water flow and water level. 1.1.3 Not applicable. NOTE Requirements for manual switches not forming part of an automatic control are contained in IEC 60669 and IEC 61058-1. 1.1.5 Replacement: This document applies to a.c. or d.c. automatic electrical air flow, water flow and water level sensing controls with a rated voltage not exceeding 690 V a.c. or 600 V d.c. 1.1.6 Replacement: This document takes into account the response value of an automatic action of a control where such a response value is dependent upon the method of mounting the control. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply. 1.1.7 Replacement: This document applies also to controls incorporating electronic devices, requirements for which are contained in Annex H. This document applies also to controls using NTC and PTC thermistors, requirements for which are contained in Annex J.
