BS EN 14154-4:2014EN 14154-4:2014 (E) 5 Introduction This European Standard has been defined as part of the work being undertaken by t
21、he European Standards Organizations (CEN/CENELEC/ETSI) under the Commission Mandate M/441. This standard utilizes the six functionalities agreed by the Smart Meters Coordination Group (SM-CG) (see Annex B) as the basis for its additional functionalities. It is not required for the Additional Functio
22、nality Device (AFD) to incorporate all functions defined in this standard. Communications for water meters are outside the scope of this standard and are covered by the appropriate parts of EN 13757-1, EN 13757-2, EN 13757-3, EN 13757-4, EN 13757-5 and EN 13757-6 which provide a number of protocols
23、and transport layers for meter communications for Gas, Water and Heat meters. The additional functionality for water meters can be provided by a number of methods; these are illustrated below, see Figure 1, and described in detail within this standard. The AFD can be integrated in the meter, attache
24、d to the meter or remote from the meter. BS EN 14154-4:2014EN 14154-4:2014 (E) 6 1 Scope This European Standard specifies definitions, requirements and testing of additional functionalities for water meters, without metrological impact, in combination with Additional Functionality Devices (AFD) and
25、in response to EU/EFTA Mandate M/441 EN. These AFDs are to be considered as “ancillary devices“ as defined in EN ISO 4064-1 and EN ISO 4064-4. This European Standard does not cover the changing of metrological software within the meter or the upload/download of metrological software. NOTE A manufact
26、urer can claim compliance only for additional functionalities described in this European Standard. It is not mandatory that an AFD complies with all additional functionalities described herein. 2 Normative references The following documents, in whole or in part, are normatively referenced in this do

37、l requirements 4.1 Types of additional functionality devices and requirements The additional functionality shall be provided by one of the following devices: AFD1; where all functions are within the same metrological enclosure as the meter; BS EN 14154-4:2014EN 14154-4:2014 (E) 8 AFD2; where the AFD
38、 is attached directly to the meter. The manufacturer shall declare the appropriate device compatibility; AFD3; where the AFD is located remotely and connected to the meter. The manufacturer shall declare the appropriate device compatibility. Figure 1 Additional functionality devices 4.2 Connection r
39、equirements 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 obscu
40、re 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 operat
41、ing 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. BS EN 14154-4:2014EN 14154-4:2014 (E
