ASTM F2128-13(R2021) pdf free download.Standard Test Method for Treestand Repetitive Loading Capability
1. Scope
1.1 This test method covers the procedures for determining the capability of climbing and ladder treestands and tripods to withstand repeated loading relative to the manufacturer’s rated capacity. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 The terminology and definitions in the referenced docu- ments are applicable to this practice. 3.2 Definitions: 3.2.1 backbar or V-bar—the adjustable component of a climbing treestand or handclimber that engages the tree to provide support. The backbar may be rigid or flexible. 3.2.2 climbing treestand—a treestand that provides both the means to ascend the tree, and allow the user to remain at a desired elevation. 3.2.3 handclimber, or climbing aid—a device to assist climbing with a climbing treestand. A structure that allows the user to support his weight when lifting a climbing treestand with his legs. 3.2.4 laddertreestand—a treestand that is secured to the tree at the elevation where the platform is located. (The ladder treestand can be secured to the tree at other locations and has steps that are used to reach the platform or hunting position.) 3.2.5 non-climbing, fixed position or hang-on treestand—a treestand that is secured to the tree at the elevation where it is used. (The user usually ascends the tree by some means and then lifts the treestand to the desired position and secures it for use.) 3.2.6 platform—the horizontal structural area of a treestand on which the user stands or places his feet, or both. 3.2.7 treestand—a device designed to be affixed to a tree or its branches so as to permit an individual to sit or stand thereon for the purpose of attaining an elevated position from which to observe, photograph or hunt. 3.2.8 two person treestand—a ladder or hang-on treestand designed and marketed for use by two persons simultaneously.
4. Summary of Test Method
4.1 A treestand is mounted so that its platform is perpen- dicular to a rigid wood or metal pole when the rate load capacity is applied parallel to the mounting pole. The load is applied vertically and is guided so that it is applied at the locations applied when ascending or descending a tree on the treestand. In the case of a ladder treestand or tripod, the load is applied to the rungs of the ladder or tripod. The test subject is noted after a certain number of loading cycles, by means of a thorough visual inspection, to determine if any structural damage such as yielding or cracking, or both, has occurred. 4.2 Stand up-sit down two-piece climbers—both seat and foot sections may be tested at the same time.
