DIN EN 12491:2016-02 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 alternat
29、ive 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 resista
30、nt 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 directi
31、on of its maximum strength. DINEN 12491:2016-02EN 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 Normati
