Hi,I am John,today i will share ASTM F2531-13,Standard Test Method for Load Capacity of Treestand Seats.
ASTM F2531-13 covers the determination of the static load capacity of treestand seats in terms of a factor of safety relative to the manufacturers rated capacity.
The use of calibrated weights requires that weight placement be accurate to assure that the load application centroid is coincident with the boundaries defined and meetsthe requirements given in 5.4. Caution should be exercised for operator protection with the use of weights in case of slippage or premature failure.
No statement is made about either the precision or biasof this test method for measuring load capacity, since the result merely states whether there is conformance to the criteria for success specified in the procedure.
Keywords of this standard:backbar; platform; treestand; tripod.
