ASTM F3544-21

Standard Test Method for Hunting Saddle Static Load Capacity

SIGNIFICANCE AND USE
5.1 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 hunting saddles and bridge in terms of a factor of safety relative to the manufacturer’s rated capacity.  
1.2 The values shared are in inch-pound units and are to be regarded as the standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
