6、ication The start of application of this standard is 2016-08-01. National foreword This standard includes safety requirements within the meaning of the Produktsicherheitsgesetz (ProdSG) (German Product Safety Act). This document (ISO 9838:2015) has been prepared by Technical Committee ISO/TC 83 “Spo

7、rts and other recreational facilities and equipment”, Subcommittee SC 4 “Snowsports equipment” (Secretariat: ASI, Austria). The responsible German body involved in its preparation was DIN-Normenausschuss Sport- und Freizeitgert (DIN Standards Committee Sports Equipment), Working Committee NA 112-03-

8、01 AA Ski- und Snowboardsportgerte. Where this standard has been identified by the Ausschuss fr Produktsicherheit (German Committee for Product Safety) and reference to it has been published in the Gemeinsames Ministerialblatt (German Joint Ministerial Gazette) by the Bundesanstalt fr Arbeitsschutz

9、und Arbeitsmedizin (BAuA) (German Federal Institute for Occupational Safety and Health), it is to be presumed that test soles for ski-binding tests which comply with this standard fulfil the relevant health and safety requirements. Attention is drawn to the possibility that some of the elements of t

However, in the origin

12、al English text of ISO 9838:2015, the title given is “Test sole form A, type A” (in the German version “Prfsohle Form A, Typ A”). Amendments This standard differs from DIN ISO 9838:2009-10 as follows: a) normative references have been updated; b) in Clause 5, the hardness degree of the material has

13、been modified; c) the standard has been editorially revised.

16、 be used for testing alpine ski-bindings for alpine skiing in accordance with ISO 9462 and ISO 9465, and a touring ski-boot (form T) or at least the bottom part of it to be used for testing touring ski-bindings for touring skiing in accordance with ISO 13992 and ISO 9465.NOTE Ski-boots have their ow

17、n International Standards (ISO 5355 and ISO 9523) that allow relatively large tolerances in defining the test sole which are generally believed to be suitable for on-slope use by skiers, but too large for reproducible laboratory measurements.2 Normative referencesThe following documents, in whole or
