Annex A
(informative)
Suggested belt approval I certification options
Where a series of belts can be shown to have the same basic construction and contain the same materials then it may be acceptable to approve / certify this series on a range or family basis (for a single category) rather than test all options. For example, test lowest and highest tensile belts both fitted with minimum and maximum thickness covers.Annex ZA

Relationship between this European Standard and the Essential
Requirements of EC 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 one means of conforming to Essential Requirements of the New Approach Directive for 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 Essential Requirements
1.5.2 Static electricity
1.5.6 Fire
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.Bibliography
