Introduction
This document is referred to in the CEN/CLC/ETSI TR 50572:2011, Functional Reference Architecture
for Communications in Smart Metering Systems, as a standard for communications between elements in
the Smart Metering Architecture. The M/441 Mandate, which led to the CEN/CLC/ETSI TR 50572, is
driving significant development of standards in smart metering.
This document has been amended to reflect significant updates in Security practices, and updates to the
OBIS model to reflect the state of the art. COSEM Classes have been removed from this document, as
they are published in the EN IEC 62056-6-2 standard and there is a risk of contradiction.

https://ec.europa.eu/energy/sites/ener/files/documents/2011_03_01_mandate_m490_en.pdf, and
