History
AVI for railways this ETS, together with ETS 300 683, is intended to become a harmonised standard, the reference of which is intended to be cited in the Official Journal of the European Communities referencing the EMC Directive. Co-ordination with ERC according to MoU needed (az 2/95). Supporting organisations: UIC.
