Relationship between this European standard and the essential requirements of
Directive 2014/30/EU [2014 OJ L96] aimed to be covered

This European standard has been prepared under the European Commission standardisation request
C(2016) 7641 final of 30.11.2016 , ('M/552'), as regards harmonised standards in support of Directive
2014/30/EU relating to electromagnetic compatibility, to provide one voluntary means of conforming to
essential requirements of Directive 2014/30/EU of the European Parliament and of the Council of 26
February 2014 on the harmonisation of the laws of the Member States relating to electromagnetic
compatibility [2014 OJ L96].
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 ZZA.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.
