d) update of information and marking requirements including environmental information requirements referencing IEC TS 63058:2021;
e) update of the constructional requirements and the corresponding tests considering safety aspects (e.g. artificial optical radiation, security aspects, limited energy source, stored charge energy circuit);
f) update of the EMC requirements according to the generic documents;
g) new requirements for reed contact magnetic switches in Annex D;
h) requirements for class II circuit devices achieved by double or reinforced insulation in Annex F;
i) update of pull-out tests in Annex G;
