17、is International Standard defines test soles representing an alpine ski-boot (form A) or at least the bottom part of it to 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

18、for testing touring ski-bindings for touring skiing in accordance with ISO 13992 and ISO 9465. NOTE Ski-boots have their own 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 b
