21、HS-,-,-ISO/TS 16407-2:2012(E) ISO 2012 All rights reserved vIntroduction This part of ISO/IEC 16407 is part of a set of standards that supports interoperability of autonomous EFC-systems, which includes ISO/TS 17575 parts 1 to 4 that define the EFC context data, their charge reports and their use of
22、 communication infrastructure. Within the suite of EFC standards, this conformance evaluation procedure defines the process and tests for conformity evaluation of Front End and Back End that comply with the requirements in ISO/TS 17575-1. This part of ISO/IEC 16407 is intended to assess Front End an
23、d Back End capabilities, assess Front End and Back End behaviour, serve as a guide for Front End and Back End conformance evaluation and type approval, achieve comparability between the results of the corresponding tests applied in different places at different times, and facilitate communications b
24、etween parties. This part of ISO/IEC 16407 is based on ISO/TS 17575-1, and the ISO/IEC 9646 family of standards on conformance test methodology.

26、TS) to evaluate the conformity of Front End and Back End to ISO/TS 17575-1. The objective of this part of ISO/IEC 16407 is to provide a basis for conformance tests for the Front End and the Back End in Electronic Fee Collection to enable interoperability between different equipment supplied by diffe
27、rent manufacturers. The present abstract test suite is directly derived from ISO/TS 17575-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edit
