Version 1.3.1 contains further enhancements to be used in the CEN approval process. TS 101 206-7 version 1.1.1 is the handover version to CEN for becoming EN 726-7. TS 101 206-3, 4 and 7 version 1.2.1 represent an update of the documents handed over to CEN for becoming EN 726-3, 4, and 7. PTS has used version 1.2.1 rather than the handover version to CEN (version 1.1.1) for producing the conformance testing specification for EN 726-3, 4 and 7 (prEN13343/4/5). ETSI has produced a set of TSs which are not a copy of any CEN published EN. The TSs are complete and consistent documents with references among themselves. It has been made clear in these TSs that they are contributions to the CEN work for publication as EN (after re-editing the references). Once published by CEN as EN, ETSI will withdraw its TSs.
