    The American Wood Protection Association (AWPA) standards for ACQ require a retention of 0.15 lb/cu ft (2.4 kg/m 3) for above ground use and 0.40 lb/cu ft (6.4 kg/m 3) for ground contact. Chemical Specialties, Inc (CSI, now Viance) received U.S. Environmental Protection Agency 's Presidential Green Chemistry Challenge Award in 2002 for ...

  3. Volume table - Wikipedia

    en.wikipedia.org/wiki/Volume_table

    A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...

  4. Log scaler - Wikipedia

    en.wikipedia.org/wiki/Log_scaler

    The Log Scaler measures the cut trees to determine the scale (volume) and quality (grade) of the wood to be used for manufacturing. When logs are sold, in order to determine the basis for a sale price in a standard way, the logs are "scaled" which means they are measured, identified as to species, and deductions for defects assigned to produce ...

    Acetylated wood is a type of modified wood that is produced through a chemical modification process and does not contain any toxic substances. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.

    Finger-jointed lumber – solid dimensional lumber lengths typically are limited to lengths of 22 to 24 feet (6.77.3 m), but can be made longer by the technique of "finger-jointing" by using small solid pieces, usually 18 to 24 inches (460–610 mm) long, and joining them together using finger joints and glue to produce lengths that can be ...

    en.wikipedia.org/wiki/Tree_volume_measurement

    The volume of the branches on the tuliptree was only 64.2% that of the trunk. [15] The President Tree (Sequoiadendron giganteum) [3] was measured in 2012 to have a trunk volume of 54,000 cubic feet (1,500 m 3) of wood and a branch volume of 9,000 cubic feet (250 m 3) of wood in the branches. In this giant tree the branch volume was only 16.7% ...

    A cord of wood. The cord is a unit of measure of dry volume used to measure firewood and pulpwood in the United States and Canada.. A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching, and compact), occupies a volume of 128 cubic feet (3.62 m 3). [1]
