Paragliding equipment - Emergency parachutes - Safety requirements and test methods

This European Standard is applicable to emergency parachutes intended for use in single-seater or two-seater paragliders. The aim of this standard is to define a method of testing the resistance to dynamic stresses of an emergency parachute and to fix from that a minimum strength level and acceptable rate of descent.

Ausrüstung für das Gleitschirmfliegen - Rettungsfallschirme - Sicherheitstechnische Anforderungen und Prüfverfahren

Diese Europäische Norm gilt für Rettungsfallschirme, die durch den Piloten ohne jede andere Unterstützung (mechanisch oder pyrotechnisch) ausgelöst werden und die zur Verwendung in einsitzigen und zweisitzigen Gleitschirmen vorgesehen sind.

EN 12491:2015 (E) 3 European foreword This document (EN 12491:2015) has been prepared by Technical Committee CEN/TC 136 “Sports, playground and other recreational facilities and equipment”, 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of an identical text or by endorsement, at the latest by May 2016, and conflicting national standards shall be withdrawn at the latest by May 2016.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 12491:2001. This standard is one of a package of standards on equipment for paragliding as follows: — EN 926-1, Paragliding equipment — Paragliders — Part 1: Requirements and test methods for structural strength; — EN 926-2, Paragliding equipment — Paragliders — Part 2: Requirements and test methods for classifying flight safety characteristics; — EN 1651, Paragliding equipment — Harnesses — Safety requirements and strength tests; — EN 12491, Paragliding equipment — Emergency parachutes — Safety requirements and test methods. In comparison with the previous edition EN 12491:2001, the following significant changes have been made: a) editorial revision; b) introduction of characteristics and requirements for steerable parachutes; c) update of test files information and items accompanying the test file; d) update of user manual content. 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 12491:2015 (E) 4 Introduction The aim of this European Standard is to enhance paraglider pilots' safety by testing to confirm that emergency parachutes are likely to be able to perform their intended function. The tests do not include any compatibility tests with alternative inner containers. Emergency parachutes shall be supplied by the manufacturer for testing complete with attachments suitable for connection to an EN 1651 paragliding harness, and parachutes will be tested as if they were so connected. These connections are made in such a way, and/or using resistant material, so that they are not subject to friction or heat failure due to the tightening or slipping possible under shock loads. Any metal link is installed in such a way as to minimize any risk of injury to the pilot in an emergency deployment, and to ensure that it will be loaded in the direction of its maximum strength. SIST EN 12491:2016



EN 12491:2015 (E) 5 1 Scope This European Standard is applicable to emergency parachutes deployed by the action of the pilot without any other assistance (mechanical or pyrotechnic), intended for use with single-seater or two-seater paragliders. 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. EN 926-1, Paragliding equipment — Paragliders — Part 1: Requirements and test methods for structural strength EN 1651, Paragliding equipment — Harnesses — Safety requirements and strength tests 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 paraglider ultra light glider with no primary rigid structure, for which take-off and landing are on foot, with the pilot (and potentially one passenger) carried in a harness (or harnesses) connected to the wing 3.2 emergency parachute emergency device intended to slow the descent of a paraglider pilot in the event of an incident in flight, which is deployed by the pilot by an intentional manual action Note 1 to entry: This may be unsteered or steerable. 3.3 riser lowest part of the parachute system, which is connected to the harness Note 1 to entry: Examples of risers are presented in Figure 1 and Figure 2. 3.4 suspension lines multiple cords connecting the emergency parachute canopy to the riser(s) SIST EN 12491:2016
