EN 131-1:2015 (E) 3 European foreword This document (EN 131-1:2015) has been prepared by Technical Committee CEN/TC 93 “Ladders”, the secretariat of which is held by DIN. This European Standard shall be given the status of 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of an identical text or by endorsement, at the latest by May 2016, and conflicting national standards shall be withdrawn at the latest by November 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 131-1:2007+A1:2011. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Compared to 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 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-joint ladders; — Part 6: Telescopic ladders; — Part 7: Mobile ladders with platform. The standards of this series are listed in Clause 2 and in the Bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 131-1:2015 (E) 4 1 Scope This European Standard defines terms and specifies the general design characteristics of ladders. It applies to portable ladders. It does not apply to ladders designed for specific professional use such as fire brigade ladders, roof ladders and mobile ladders. NOTE 1 For multiple hinge joint ladders EN 131–4 applies. NOTE 2 For telescopic ladders EN 131–6 applies. NOTE 3 For mobile ladders with platforms EN 131–7 applies. NOTE 4 This standard does not apply to step stools for which EN 14183 applies. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
