(Test Method)Standard Test Method for Treestand Static Load Capacity
Standard Test Method for Treestand Static Load Capacity
SIGNIFICANCE AND USE
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 treestands in terms of a factor of safety relative to the manufacturer's rated capacity.
1.2 The values stated are in inch-pound units and are to be regarded as the 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.
