IEC 61133:2016 is available as IEC 61133:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61133:2016 specifies general criteria to demonstrate by testing that newly constructed complete railway vehicles conform with standards or other normative documents. This International Standard, as a whole or in part, applies to all railway vehicles except special purpose vehicles such as track-laying machines, ballast cleaners and personnel carriers. The extent of application of the standard for particular vehicles will be specifically mentioned in the contract, to take account, where necessary, of any legislative requirements. The main technical changes with regard to the previous edition are as follows:
- references to standards other than international have been removed from the main text so the notes refer solely to Annex B;
- Annex B has been updated with the latest European information,
- and cross-references between the TSIs and ENs and the clauses of IEC 61133 have been added.
