(informative)
Relationship between this European standard and the safety objectives of
Directive 2014/35/EU [2014 OJ L96] aimed to be covered

This European standard has been prepared under a Commission’s standardisation
request relating to harmonised standards in the field of the Low Voltage Directive,
M/511, to provide one voluntary means of conforming to safety objectives of Directive
2014/35/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 the making available
on the market of electrical equipment designed for use within certain voltage limits
[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 ZZ.1
confers, within the limits of the scope of this standard, a presumption of conformity
with the corresponding safety objectives o
