During consulting audits, we regularly see three mistakes that originate from using old, illegal PDFs:
Official CEI standards come with errata sheets (correction pages). Free scanned PDFs never include these. One wrong temperature class (T-Class) listed in an obsolete document could cause a catastrophic explosion.
CEI 31-35 Annex A defines the mandatory marking block. A compliant label looks like this:
CE 0470 II 2 G Ex db IIB T4 Gb
Do not accept any equipment that lacks this marking. Your PDF provides the verification checklists for each character.
