This International Standard has been prepared to give guidance to machinery designers and writers of product safety standards on how to design and select interlocking devices associated with guards. It provides measures to minimize defeat of interlocking devices in a reasonably foreseeable manner.
Relevant clauses used alone or in conjunction with provisions from other standards, may be used as a basis for verification procedures for the suitability of a device for interlocking duties.
The structure of safety standards in the field of machinery is as follows:
a) Type-A standards (basic safety standards) giving basic concepts, principles for design, and general aspects that can be applied to all machinery;
b) Type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery:
— Type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
— Type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure sensitive devices, guards);
c) Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines.
The requirements of this document can be supplemented or modified by a type-C standard.
Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC
This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the New Approach Directive Machinery 2006/42/EC.
Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard confers, within the limits of the scope of this standard, a presumption of conformity with the relevant Essential Requirements 126.96.36.199 Interlocking movable guards of Annex I of that Directive and associated EFTA regulations.
WARNING: Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard.
