and in accordance with the relevant guidance given in ISO/IEC 9646-7 [i.4]. The ISO standards for the methodology of
conformance testing (ISO/IEC 9646-1 [i.2] and ISO/IEC 9646-2 [i.3]) as well as the ETSI rules for conformance testing
(ETSI ETS 300 406 [i.5]) are used as a basis for the test methodology.

5 Test Purposes (TPs)
5.1 Introduction
5.1.1 TP definition conventions
The TP definition is built according to ETSI EG 202 798 [i.1].
5.1.2 TP Identifier naming conventions
The identifier of the TP is built according to table 4.
Table 4: TP naming convention
Identifier TP//// Example
= root IS_TLM
 IS_RLT
 IS_IVI
 IS_TLC
= group MSGF Message Dissemination
 EVUP Event Update
 EVGN Event Generation
 EVTR Event Termination
 COMM Communication
 GFQ Timers
 SEC_SND Send behaviour of Security
Send behaviour of Specific
 SSP_SND
service Permission
Receive behaviour of Specific
 SSP_RCV
service Permission
= type of testing BV Valid event tests
= sequential number 01 to 99

5.1.3 Rules for the behaviour description
The description of the TP is built according to ETSI EG 202 798 [i.1].
SAE J2735 [1] does not use finite state machine concept. As consequence, the test purposes use a generic "Initial State"
that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, the IUT shall be left in
this "Initial State", when the test is completed.
Being in the "Initial State" refers to the starting point of the initial device configuration. There are no pending actions,
no instantiated buffers or variables, which could disturb the execution of a test.
ETSI

11 ETSI TS 103 191-2 V1.2.1 (2017-03)
5.1.4 Sources of TP definitions
All TPs have been specified according to SAE J2735 [1] and ETSI TS 103 301 [2].
5.1.5 Mnemonics for PICS reference
To avoid an update of all TPs when the PICS document is changed, table 5 introduces mnemonics name and the
correspondence with the real PICS item number.
The PICS item column refers to tables and items of ETSI TS 103 191-1 [3]. The 'PICS item' as defined in ETSI
TS 103 191-1 [3] shall be used to determine the test applicability.
