It does not apply to static watt-hour payment meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems). It applies to payment meters for indoor application only, where the payment meter shall be mounted as for normal service Functional requirements that apply to payment meters are also defined and include informative basic functional requirements and tests for the prepayment mode of operation in Annex A.
