 fundamental modification of the annexes specifying the protective types and addition of further

examples of application;

 moving of the annex indicating the relationship between this European Standard and the Essential

Requirements of EU Directive 2006/42/EC to informative Annex ZA;

 cancellation of the annex indicating the relationship between this European Standard and the

Essential Requirements of EU Directive 98/37/EC.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

Annex ZA
(informative)
Relationship between this European Standard and the essential
requirements of Directive 2006/42/EC aimed to be covered

This European Standard has been prepared under a Commission’s standardization request "M/396

Mandate to CEN and CENELEC for Standardisation in the field of Machinery" to provide one voluntary

means of conforming to essential requirements of Directive 2006/42/EC of the European Parliament

and the Council of 17 May 2006 on machinery, and amending Directive 95/16/EC (recast).

Once this standard is cited in the Official Journal of the European Union under that Directive,

compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of

the scope of this standard, a presumption of conformity with the corresponding essential requirements

of that Directive and associated EFTA regulations.
