1、Designation: F 2124 05An American National StandardStandard Practice forTesting Treestand Ladder, Tripod Stand and Climbing StickLoad Capacity1This standard is issued under the fixed designation F 2124; the number immediately following the designation indicates the year oforiginal adoption or, in th
2、e case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides guidance for testing the loadcapacity of ladder and tripod typ
3、e treestands. This practice alsoapplies to climbing sticks which shall meet the same require-ments as the steps to ladder and tripod type stands. For changesto this specification since the last issue, refer to the Summaryof Changes section at the end of the standard.1.2 The values stated are in inch
4、-pound units and are to beregarded as the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of

15、reasonable testprocedure in those instances where no standard exists today.6. Procedure6.1 The following methods are recommended for individualunits and situations:6.1.1 An individual test unit of the specified model shall beselected at random.6.1.2 The test units shall first be visually inspected f
16、or anyflaws and defects, missing parts, etc., and any discrepancies arenoted. The test unit shall also be checked, and so noted, toassure that instructions are included with the unit.6.1.3 A test shall be performed to determine the static loadcapacity of the platform, steps, and seat (when present).
17、 Testsshall be performed on the platform, seat section (when present)and 25 % or a minimum of one of the steps in accordance withTest Method F 2126. Deflection measurements shall not beperformed on the steps.6.1.4 A stability test on the platform shall be performed ingeneral accordance with Test Met
18、hod F 2125.6.1.5 A repetitive loading test shall be performed on at leastone of the stands steps with the test subject assembled and inplace against the test pole in accordance with Test MethodF 2128. The steps shall be selected at a location approximatelytwo-thirds of the total assembled vertical h
19、eight. The totalnumber of load cycles shall be the number of steps multipliedby 500 (based on the usage of cycle up and down with eachuse, 25 days per year for 10 years).6.1.6 This section applies to test subjects that are designedto be used by two people at the same time, and thus have higherrated
20、loads to include the weight of two people. Static testingat twice the rated load and stability testing at one times therated load shall be performed on the platform section, inaccordance with Test Methods F 2126 and F 2125 respectfully.However, static and repetitive testing at one times the ratedloa
21、d shall be performed on the step according to Test MethodF 2128 since only one person can stand on the ladder step at atime.7. Failure Criterion7.1 During all testing yielding permanent deformation,cracks or other structural defects shall be cause for failure.Visual inspection shall be the main insp
22、ection method; how-ever, other non-destructive test methods may be used todetermine if yielding has occurred.8.
