If the template of Annex A of the EPB standard can be filled in without any violation of the template and without de facto altering the provisions of the EPB standard, a National Annex or a National Datasheet may be used. See FAQ on the difference between these two options.
A National Annex to the EPB standard is not an option if the template is violated or if the filled in national choices lead to de facto alterations of the normative provisions of the EPB standard. In that case the only choice is a National Datasheet.
