9、tional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has be
10、en established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stan
11、dardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 14119 was prepared by Technical C
12、ommittee ISO/TC 199, Safety of machinery. ISO 14119 has been published by the European Committee on Standardization (CEN) as EN 1088. Annexes A to P of this International Standard are for information only. ISO 14119:1998(E) ISO iv Introduction This International Standard has been prepared to give gu
13、idance to machinery designers and writers of product safety standards on how to design or to select interlocking devices associated with guards. It may also be used as guidance in controlling the risk where there is no product safety standard for a particular machine. Relevant sections of this Inter
14、national Standard, used alone or in conjunction with provisions from other standards, can be used as a basis for verification procedures for the suitability of a device for interlocking duties. A statement by a manufacturer that an interlocking device complies with this International Standard, witho
15、ut reference to specific clauses, has no meaning. Annexes A to N contain only examples complying with the principles set out in this International Standard, and the application of which has been validated by experience. Other solutions may be adopted, provided that they comply with the same principl

17、ocking devices associated with guards (as defined in 3.23.1 “interlocking device interlock“, 3.22.4 “interlocking guard“ and 3.22.5 “interlocking guard with guard locking“ of ISO/TR 12100-1:1992). It also provides requirements specifically intended for electrical interlocking devices (see clause 6).
18、 This International Standard covers the parts of guards which actuate interlocking devices. NOTE Requirements for guards are given in prEN 953. The processing of the signal from the interlocking device to stop and immobilize the machine is dealt with in ISO 13849-1. 2 Normative references The follow

All standards are subject to revision, and parties to agreements based on this International Standard are encou
