NOTE Additionally for the purposes of this part of the European Standard, the following terms and definitions only related to additional functionalities apply. 3.1 functionality process which constantly or at defined intervals, automatically or on demand, performs specific activities such as sampling data, reading a data set, verifying or changing a status, or activating a switch 3.2 additional functionality functionality that a smart meter provides, over and above the metrological functionality covered by the Measuring Instruments Directive SIST EN 14154-4:2015

Figure 1 — Additional functionality devices 4.2 Connection requirements The AFD2 and AFD3 shall be connected to the meter and tested as a combined unit in all the tests given in 4.11.2 to ensure the connection of the AFD to the meter has no metrological influence. The connection of the AFD to the meter or any labelling on the meter or the AFD shall not obscure or damage any metrological seal of the meter. The primary indication on the meter shall not be obscured by the connection of the AFD and the indicating device shall be accessible to the consumer without the use of tools. 4.3 Environmental conditions The AFD shall work with the meter at all operating conditions of the meter as required by the appropriate standards. Any AFD should be suitable to meet one of the environmental classes from EN ISO 4064-1, A.2 and A.3 and the related tests. An AFD3 may have a different environmental class to that of the meter.
