ASTM F2531-13

Standard Test Method for Load Capacity of Treestand Seats

SIGNIFICANCE AND USE
4.1 This test method is intended for quality assurance and production control purposes.
SCOPE
1.1 This test method covers the determination of the static load capacity of treestand seats in terms of a factor of safety relative to the manufacturers 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 appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

3. Summary of Test Method
3.1 A treestand is mounted so that its platform is perpendicular or slightly above horizontal to a rigid wood or metal pole when
the rated load is applied parallel to the mounting pole. The treestand seat frame is equipped with deflection measurement devices.
The ladder and tripod do not require deflection measurements to be taken. The load is applied incrementally and recordings are
