Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 89/686/EEC
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association and supports essential requirements of the EU Directive
89/686/EEC on PPE.
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 clauses of this
standard, together with the relevant requirements given in the product standards, confers within the limits of
the scope of those standards, a presumption of conformity with the corresponding Essential Requirements 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
