Standard Test Method for Treestand Static Stability
SCOPE
1.1 This test method covers the determination of the static stability of treestands relative to the manufacturer's rated capacity.
1.2 The values stated are in inch-pound units and are to be regarded as 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 determine the applicability of regulatory limitations prior to use.
