29、 to be a harmonized standard to provide one means of conforming with the essential safety requirements of the Machinery Directive and associated EFTA Regulations. Its primary purpose is to give guidance to machinery designers and writers of type C standards on how to design or to select interlocking
30、 devices associated with guards with a view to complying with the relevant essential safety requirements of the EC Machinery Directive (see foreword). It may also be used as guidance in controlling the risk where there is no type C standard for a particular machine. Relevant sections of t h i s stan
31、dard, used alone or in codunction 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 EN 1088, without reference to specific clauses,
32、has no meaning. The annexes A, B., P are informative. Annexes A to N contain only examples complying with the principles set out in this standard, and the application of which has been validated by experience. Other solutions may be adopted, provided that they comply with the same principles. Annex
33、P is entitled Bibliography. 1 Scope This standard specifies principles for the design and selection - independent of the nature of the energy source - of interlocking deblces associated with guards (as defined in 3.23.1 interlocking device (interlock), 3.22.4 interloclang guard and 3.22.5 interlocki
34、ng guard with guard locking of EN 292-1 : 1991). It also provides requirements specifically intended for electrical interlocking devices (see clause 6). This standard covers the parts of guards whch actuate interlocking devices. Requirements for guards are given in prEN 953. The processing of the si
35、gnal from the interlocking device to stop and immobilize the machine is dealt with in prEN 954-1. 2 Normative references T h i s European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the te
