Annex ZA (informative) Relationship between this European Standard and the essential requirements of Directive 2006/42/EC machinery, and amending Directive 95/16/EC (recast) [2006 L157] aimed to be covered

This European Standard has been prepared under a Commission’s standardization request M/396 to provide one voluntary means of conforming to essential requirements of Directive 2006/42/EC of the European Parliament and of the Council of 17 May 2006 on machinery, and amending Directive 95/16/EC (recast) [2006 L157].

Licensed copy:Royal Haskoning, 14/06/2017, Uncontrolled Copy, © BSI

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. Table ZA.1 — Correspondence between this European Standard and Directive 2006/42/EC [2006 L157] Essential Requirements of Directive 2006/42/EC

Clause(s) / subclause(s) of this EN

1.5.15 “Risks of slipping, tripping or falling”

All

1.6.2 “Access to operating position and service points”

All

Remarks / Notes

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. IMPORTANT: Compliance with the requirements of EN ISO 14122-1 and a relevant access-specific part of EN ISO 14122 is necessary to achieve presumption of conformity.
