8、nd forces involved in humanwalking motion.The important features of the walking motionproduced by the mechanism are defined as follows:4.1.1 At the beginning of a step(the point where the heel ofthe footwear touches the walking surface)the leg pylonattached to the prosthetic foot shall form an angle
9、 of 16 6 5(relative to a line perpendicular to the walking surface)asshown in Fig.2.4.1.2 At the end of a step(the point where the toe of thefootwear departs from the walking surface)the leg pylon shallform an angle 31 6 5(see Fig.2).4.1.3 Each step shall begin with no force being exerted onthe foot
10、wear and with the footwear not in contact with thewalking surface.When the footwear contacts the walkingsurface,it shall remain in contact during the entire supportphase of the step and then depart from the walking surface atthe end of the step.4.1.4 During the support phase of each step,a downwardf
11、orce shall be applied to the footwear to simulate the weight ofthe user.The force shall equal one bodyweight of the typicalprospective user,with a tolerance of 610%,unless a differentforce is specified.Table 1 lists the body masses of 50thpercentile adults and children,and the equivalent one body-we
12、ight downward force levels.If no other downward force isspecified,the values in Table 1 shall be used.NOTE1The force under the prosthetic foot can be measured with aload cell or force plate.4.2 Mens 26-cm(U.S.Size 9)or Womens 24-cm(U.S.Size7)Right or Left Prosthetic Foot,shall be used unless a diffe
13、rentsize is specified.The foot shall closely approximate the shape,texture,and flexibility of a human foot.1This test method is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing Surfaces,and Facilities and is the direct responsibility ofSubcommittee F08.54 on Athletic Footwear.
