22、th forcibly guided (mechanically linked) contacts FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation
23、on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
24、Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparatio
25、n. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
26、of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are ma
27、de to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transp
28、arently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent ce
29、rtification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability
30、shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
31、legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this
32、publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61810-3 has been prepared by IEC technical committe

The text of this standard is based on the following documents: FDIS Report on voting 94/378/FDIS 94/382

BS EN 61810-3:2015 4 IEC 61810-3:2015 IEC 2015 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 6181

The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data relat

BS EN 61810-3:2015IEC 61810-3:2015 IEC 2015 5 INTRODUCTION This Standard applies to elementary relays in which special design and constructional measures are used
37、to ensure that make (normally-open) contacts cannot assume the same state as break (normally-closed) contacts. These relays can be used in self-monitoring control systems, e.g. safety-related control systems. BS EN 61810-3:2015 6 IEC 61810-3:2015 IEC 2015 ELECTROMECHANICAL ELEMENTARY RELAYS Part 3:
38、Relays with forcibly guided (mechanically linked) contacts 1 Scope This part of IEC 61810 specifies special requirements and tests for elementary relays with forcibly guided contacts, also known as mechanically linked contacts. These special requirements apply in addition to the general requirements
39、 of IEC 61810-1. NOTE 1 This standard does not apply to electromechanical control circuit devices as described in IEC 60947-5-1. NOTE 2 IEC 61810-2-1 provides guidelines for the assignment of reliability values. NOTE 3 Contacts that are not mechanically linked (forcibly guided) are not considered in
40、 this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc

43、omitted for clarity. SOURCE: IEC 60050-444:2002, 444-01-03, modified modification of the definition 3.2 failure to open fault condition when a contact does not open when expected to do so 3.3 failure criteria specified conditions to judge if a fault or malfunction is a failure BS EN 61810-3:2015IEC
44、61810-3:2015 IEC 2015 7 3.4 fault fault condition deviation of the existing condition from the expected condition 3.5 failure termination of the ability of an item to perform a required function as defined in the failure criteria 3.6 relay with mechanically linked contacts relay with forcibly guided
45、 contacts elementary relay with at least one make contact and at least one break contact and including mechanical measures to prevent any make contact(s) and any break contact(s) being in the closed position simultaneously 3.7 type A relay in which all contacts are mechanically linked 3.8 type B rel
46、ay containing contacts that are mechanically linked to each other as well as contacts that are not mechanically linked 4 Functional requirements 4.1 Forcibly guided (mechanically linked) operation The relay shall be designed such that if a make contact is closed, none of the mechanically linked brea
47、k contacts can close and that if a break contact is closed, none of the mechanically linked make contacts can close. These requirements apply throughout the lifetime of the relay and under reasonably foreseeable failure conditions. The effects of reasonably foreseeable breakage of and/or wear to par
48、ts of the elementary relay shall not nullify the function of forcibly guided (mechanically linked) operation. Contact gaps of open contacts shall be greater than 0,5 mm for single break contacts and 0,3 mm each for double break contacts throughout the manufacturers specified endurance of the relay.
49、Operation of forcibly guided (mechanically linked) contacts means that if any make contact fails to open when the relay is de-energized, none of the break contacts shall close. If any break contact fails to open when the relay is energized, no make contact shall close. 4.2 Changeover contacts Only break contacts and make contacts are covered by this standard; in the case of relays that include changeover contacts, either the make circuit or the break circuit of a changeover cont
