This document explains the reasoning behind the requirements and procedures given in EN 13791<\/span><\/span> [1<\/span>] and why some concepts and procedures given in EN 13791:2007<\/span><\/span> [2<\/span>] were not adopted in the 2019 revision. The annex comprises worked examples of the procedures given in EN 13791:2019<\/span><\/span>.<\/p>\n
