Device Selection Methodology
1
Introduction
This document is the Device Selection Methodology (DSM), which is published
following its consultation between the 12th September and 13th October 2014. The
DSM sets out the process by which Devices will be selected for use in testing1, and
de-selected, by the DCC in accordance with the provisions of the Smart Energy Code
(SEC)2. In selecting Devices via the DSM, the DCC will not give any consideration to
the relative ‘quality’ of one Device in relation to another. Neither will the DCC test the
functionality of the Devices.
1.1
Test Phases
The manner in which the Devices will be used during each
ach test phase is described
below.
Systems Integration Testing (SIT)
SIT tests the capability of the DCC systems, together with communication
ommunications hubs, to
interoperate with each other and with the Registration Data Provider (RDP)
(
systems.
This testing will be undertaken with all available communications hub
ub variants and
with the metering equipment that is obtained via this selection methodology. Users
will not participate in this test phase and Service
Service Requests will be injected into the
DCC User Gateway via a service user simulator.
Interface Testing (IT) and User Entry Process Tests (UEPT)
Prospective users
sers may conduct User Entry Process Tests (UEPT) during the
Interface Test stage3. UEPT will be conducted
onducted against the metering Device Models
with which the DCC successfully completes SIT. These Devices will also be used as
the basis for conducting UEPT4 during the End to End Test stage and Enduring Test
phase.
1.2
Types of Meter Devices
The minimum criteria
ia that must be met by selected Devices are set out in the SEC
which requires that Devices are:
SMETS compliant, provided that they need not (where the Secretary of State so
directs) have a ZigBee Alliance Assurance Certificate or DLMS Certificate and

Systems Integration Testing (SIT), Interface Testing (IT) and User Entry Process Tests (UEPT) will be
undertaken using (to the extent reasonably practicable) actual Devices rather than Test Stubs or other
alternative arrangements.

Version 3 of the SEC, effective 31 July 2014

The SEC obliges all Large Supplier Parties to be ready to commence UEPT at the start of the Interface
Test stage

UEPT will be conducted using the Device Models that are selected via this DSM. In accordance
accordan with
Section H14 .9 b) of the SEC, the Panel may approve the use of alternative Device models from time to
time. The manner in which these alternative Device Models will be selected will be set out in the
Enduring Test Approach Document which will be published
p
on the DCC website.
