Relationship between this European Standard and the essential
requirements of EU Directive 2014/68/EU (PED) aimed to be covered
This European Standard has been prepared under a Commission's standardization request M/071
"Mandate to CEN for standardization in the field of pressure equipment" to provide one voluntary
means of conforming to essential requirements of Directive 2014/68/EU (PED) on the harmonisation of
the laws of the Member States relating to the making available on the market of pressure equipment.
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.
