Division 5.3 Constituents performances and specifications

United Kingdom

For each basic interoperability constituent or group of interoperability constituents, the tables in chapter 5 describe:

In column 3, the functions and interfaces. Note that some interoperability constituents have functions and/or interfaces that are optional.
In column 4, the mandatory specifications for the conformity assessment of each function or interface, as far as relevant, by reference to the relevant section of chapter 4.
In column 5, the modules to be applied for conformity assessment, which are described in chapter 6 of this TSI.

Note that the requirements of section 4.5.1 (Responsibility of manufacturer of equipment) apply to each basic interoperability constituent or group of interoperability constituents.
