11、rigid wood ormetal pole when the rated load is applied parallel to themounting pole.A fixed position or ladder treestand shall bemounted with the platform perpendicular to the mounting pole.A tripod stand shall be positioned so that the platform isperpendicular to the application of the load.A climb
12、ing stickshall be mounted such that the steps are perpendicular to thepole.The platform is equipped with deflection measurementdevices.The load is applied step-wise and recordings are madeof the load and deflection at each step until yielding orpermanent deflection occurs or until twice the rated lo
13、ad isapplied.The ladder,tripod and climbing sticks do not requiredeflection measurements be taken.5.Significance and Use5.1 This test method is intended for quality assurance andproduction control purposes.1This test method is under the jurisdiction of ASTM Committee F08 on SportsEquipment,Playing S
