3 Foreword This document (EN 131-4:2007) has been prepared by Technical Committee CEN/TC 93 “Ladders”, the se-cretariat 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 November 2007, and conflicting national standards shall be with-drawn at the latest by November 2007. This European Standard is one of a series about ladders. Other standards of this series are listed in Clause 2. 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, Cyprus, Czech Re-public, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

If the decking component fits within the stiles the gap shall be no more than 5 mm. If the decking component fits across the stiles, the overhang shall be no more than 25 mm on each side. The platform shall be centred at ± 10 mm in relation to the longitudinal axis of the ladder. Where decking components consist of multiple elements they shall be assembled such that a person cannot fall through them.

To test their operation, hinge joints (lateral and longitudinal hinge joint ladders) shall withstand the cyclic tests. A pair of hinge joints comprising the maximum number of positions shall be subjected to a series of 4 000 cycles from the closed position to the fully open position. The hinge joint shall be locked and unlocked in each of its positions during the course of each cycle at the normal utilisation speed. No oil shall be added to the hinge joints during the tests. Requirement: Automatic locking function shall operate with no manual intervention for a duration of 4 000 cycles. 6.2.4 Test of the ladder in the platform position 6.2.4.1 General The tests shall be conducted on the complete assembly of deckin
