ANNEX ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU 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 EU Directive 2006/42/EC on machinery.
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 Z.A.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding essential requirements
of that EU Directive 2006/42/EC, and associated EFTA regulations.
Table ZA.1 — Correspondence between this European Standard and EU Directive 2006/42/EC
Essential Requirements of Clause(s)/sub-clause(s) of Remarks/Notes
EU Directive 2006/42/EC this EN
1.5.10 radiation Entire standard
1.5.12 laser radiation Entire standard

WARNING 1 — Presumption of conformity stays valid only as long as a reference to this European
Standard is maintained in the list published in the Official Journal of the European Union. Users of this
standard should consult frequently the latest list published in the Official Journal of the European
Union.
WARNING 2 — Other Union legislation may be applicable to the product(s) falling within the scope of
this standard.
