ASTM F472-11 (R2021) pdf free download.Standard Terminology for Geometry of Alpine Skis.
1.1 This terminology covers the terms required to describe the geometry of Alpine skis and does not cover special purpose skis.
1.2 The terms are presented in a sequence considered to he the most logical, with definitions presented later calling upon those presented earlier.
tail turn-up length, lT—the projected length of the tail turn-up, measured from the ski tail to the contact point where a 0.5-mm feeler gauge intersects the running surface with the ski body pressed against a plane surface.
shovel length, ls—the projected length of the thrward turn-up. measured from the tip to the contact point where a 0.5-mm feeler gauge intersects the running surface with the ski body pressed against a plane surface.
contact length, lC—the difference between the projected length, L,1 and the sum of ‘ plus l or l. = L, — (li. +
tail height, hT,—the height of the underside of the tail from a plane surface with the center of the ski body pressed against that surface.
tip height, hs-the height of the underside of the tip from a plane surface with the center of’ the ski body pressed against that surface.
thickness, t—thickness, measured perpendicular to the running surface. XA indicates the location of thickness measurement from the tail of the ski.
width, b—total distance measured perpendicular to the center line on the running surface. X,indicates the location of ski width from the tail of the ski.
heel, bH—the widest part of the ski in the tail section of the ski.
waist, bM,—the narrowest point of the ski body between the heel and shoulder.
shoulder, bV-the widest point, of the ski in the shovel section of the ski.ASTM F472 pdf download.
