122 Part 2-15: Particular requirements for automatic electrical
123 air flow, water flow and water level sensing controls
125 FOREWORD
126 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
127 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
128 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
129 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
130 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
131 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
132 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
133 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
134 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
135 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
136 consensus of opinion on the relevant subjects since each technical committee has representation from all
137 interested IEC National Committees.
138 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
139 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
140 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
141 misinterpretation by any end user.
142 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
143 transparently to the maximum extent possible in their national and regional publications. Any divergence between
144 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
145 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
146 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
147 services carried out by independent certification bodies.
148 6) All users should ensure that they have the latest edition of this publication.
149 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
150 members of its technical committees and IEC National Committees for any personal injury, property damage or
151 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
152 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
153 Publications.
154 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
155 indispensable for the correct application of this publication.
156 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
157 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
158 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
159 may be required to implement this document. However, implementers are cautioned that this may not represent
160 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
161 shall not be held responsible for identifying any or all such patent rights.
162 IEC 60730-2-15 has been prepared by IEC technical committee 72: AUTOMATIC ELECTRICAL
163 CONTROLS. It is an International Standard.
164 This 4.0 edition cancels and replaces the 3.0 edition published in 2017. This edition constitutes
165 a technical revision.
166 This edition includes the following significant technical changes with respect to the previous
167 edition:
168 a) adoption to IEC 60730-1 Ed.6.0 with all of its significant changes to IEC 60730-1 Ed.5.0
IEC CDV 60730-2-15 ED4 © IEC 2024 -6- 72/1433/CDV
170 The text of this International Standard is based on the following documents:
Draft Report on voting
XX/XX/FDIS XX/XX/RVD
172 Full information on the voting for its approval can be found in the report on voting indicated in
173 the above table.
174 The language used for the development of this International Standard is English.
175 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
176 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
177 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
178 described in greater detail at www.iec.ch/publications.
179 A list of all parts of the IEC 60730 series, under the general title: AUTOMATIC ELECTRICAL
180 CONTROL, can be found on the IEC website.
181 This part 2-15 is intended to be used in conjunction with IEC 60730-1. It was established on the
182 basis of the sixth edition of that standard (2022). Consideration may be given to future editions
183 of, or amendments to, IEC 60730-1.
184 This part 2-15 supplements or modifies the corresponding clauses in IEC 60730-1, so as to
185 convert that publication into the IEC standard: Particular requirements for electric actuators.
186 Where this part 2-15 states "addition", "modification" or "replacement", the relevant require-
187 ment, test specification or explanatory matter in part 1 should be adapted accordingly.
188 Where no change is necessary part 2-15 indicates that the relevant clause or subclause applies.
189 In the development of a fully international standard it has been necessary to take into
190 consideration the differing requirements resulting from practical experience in various parts of
191 the world and to recognize the variation in national electrical systems and wiring rules.
192 The reader's attention is drawn to the fact that Annex Q, Annex R, Annex S, and Annex T list
193 all of the "in-some-country" clauses on differing practices of a less permanent nature relating
194 to the subject of this document.
195 In this publication:
196 1) The following print types are used:
197 – requirements proper: in roman type;
198 – test specifications: in italic type;
199 – explanatory matter: in smaller roman type.
200 – Defined terms: bold type.
201 2) Subclauses, notes or items which are additional to those in Part 1 are numbered starting
202 from 101, additional annexes are lettered AA, BB, etc.
