ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended
13、for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

21、ng tests3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1ski brakeretention device for alpine skiing which is integrated into the ski binding and which is designed to slow down a ski which has come off after the release of a ski bindingNote 1 to
22、entry: Integrated ski brakes represent the state of the art.3.2course of fallarea that can be passed over by a skier after a fall, defined by the length of which corresponds to the braking distance of the skier measured between the point of fall and the stoppage, and the width4 Requirements4.1 Compa
23、tibility with binding functionThe ski brakes shall comply with the requirements in ISO 9462 and ISO 5355, which are relevant for ski brakes. ISO 2015 All rights reserved 1BS ISO 11087:2015ISO 11087:2015(E)4.2 Interference with skiingThe ski brake shall not interfere with skiing. It shall be designed
24、 to prevent a catching of the ski or a skidding due to premature contact of the ski brake with the slope during skiing, even in steep terrain. During skiing, the ski brake shall not switch into the braking position without the need to do so.4.3 Mechanical stabilityThe design of the ski brake shall b
25、e able to withstand, without damage, the loads occurring in practice.4.4 Functional reliabilityCold, snow, and icing shall not interfere with the proper release of the ski brake.4.5 Automatic functionThe ski brake shall release independently, without handling by the skier. If the ski brake is provid
26、ed with a locking mechanism, this locking mechanism shall be automatically released after having stepped into the binding. The operation of the ski brake can be set out of function by means of tools of inserts, if necessary, to facilitate the maintenance or care of the ski equipment. In this case, t
27、he device shall be designed in such a way as to prevent stepping into the binding without removing the inserts or tools. If this is not possible, a clear statement shall be provided with the insert or with the ski brakes information material.4.6 External designThe external design of the ski brake sh
28、all be such that, during correct use, there is no greater risk for the skier to get injured by the ski brake than, for example, by the ski binding itself.4.7 Braking effectThe ski brake shall slow down the ski from every possible position on the slope, independent of snow conditions and the nature o
29、f ground that can be found during skiing. The ski shall stop within the course of fall with a maximum width of 5 m.5 Test methods5.1 SamplingTwo complete binding/brake systems (including plates, if any) are required for the test.One test sample shall be selected for each laboratory test (one sample
30、for the tests according to 5.4.6)If one of the selected test samples does not meet the requirements, two substitute test samples shall be selected, which have to meet the requirements in order to pass the tests.2 ISO 2015 All rights reservedBS ISO 11087:2015ISO 11087:2015(E)5.2 Apparatus5.2.1 Impact
