11、to the mounting pole.The load isapplied vertically and is guided so that it is applied at thelocations applied when ascending or descending a tree on thetreestand.In the case of a ladder treestand or tripod,the load isapplied to the rungs of the ladder or tripod.The test subject isnoted after a cert
12、ain number of loading cycles,by means of athorough visual inspection,to determine if any structuraldamage such as yielding or cracking,or both,has occurred.4.2 Stand up-sit down two-piece climbersboth seat andfoot sections may be tested at the same time.5.Significance and Use5.1 This test method is
13、intended for quality assurance andproduction control purposes with recognition that individualusage will vary considerably.This test method is not intendedto be an independent material or product-acceptance test.6.Apparatus6.1 Arigid,round wood or metal pole,preferably vertical,isused to mount the s
