Annex G (informative) - Measurement of creepage distances
        and clearances
Annex H (informative) - Correlation between the nominal
        voltage of the supply system and the rated impulse
        withstand voltage of equipment
Annex J (informative) - Items subject to agreement between
        manufacturer and user
Annex L (normative) - Terminal marking and distinctive number
