IEC 62888-5:2018 pdf download.Railway applications – Energy measurement on board trains – Part 5: Conformance test
1 Scope
This part of IEC 62888 specifies the conformance test arrangements for newly manufactured EMS installed on a traction unit. This includes the integration conformance test and installation conformance test. In addition, this document also specifies the conformance test procedures for device and ancillary component replacement (e.g. due to damage in service), and periodic check to verify the EMS conformance test remains valid. The assessment methods d) to j) in 4.3 apply at EMS system level. The methods are covered by IEC 62888-5 for Level 1 and by IEC 62888-6 for Level 2 and Level 3. This document does not include elements related to conformance test aspects other than design review and testing provisions for the products, processes or services specified. Consequently, this document does not delete, change or interpret the general requirements for conformance test procedures and vocabulary detailed in ISO/IEC 1 7000. This document does not cover the conformity assessment schemes that are the responsibility of ISO policy committee “Committee on conformity assessment” (ISO/CASCO).

4 Conformance test approach
4.1 General This clause specifies the structure and methodology for the conformance test. The procedures, design review requirements, testing requirements, and conformance test documentation requirements are specified in Clause 5. Completion of devices level conformance test is a pre-requisite to carry out EMS conformance test. The conformance test is undertaken in the following key stages: a) device level; b) EMS level; c) EMS re-verification and device / ancillary component replacement. Stage 1 is mandatory for newly manufactured devices and is covered by IEC 62888-2, IEC 62888-3 and IEC 62888-4. Stages 2, 3 are mandatory for every EMS in accordance with the scope as specified in Clause 1 . The conformance test, undertaken during stages 2 and 3, deals primarily with system level requirements, and it does not replicate the detail in stage 1 .
