This European Standard shall be given the status o
13、f a national standard, either by publication of an identical text or by endorsement, at the latest by May 2016, and conflicting national standards shall be withdrawn at the latest by November 2016.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Compared to
15、 EN 131-1:2007+A1:2011, the following modifications have been made in order to improve the stability of ladders in use: a) in figures stabilizers or wider base width for leaning ladders were introduced; b) further terms 3.48, 3.49 and 3.50 for stabilizers were added in Clause 3; c) requirements for
16、minimum base width for leaning ladders were specified in 4.2.1, Table 2 and Table 6. EN 131, Ladders, is one of a series about ladders: Part 1: Terms, types, functional sizes the present document; Part 2: Requirements, testing, marking; Part 3: User Instructions; Part 4: Single or multiple hinge-joi
