Testing wood, destructive

Property enhancement by acetylation has been frequently reported over the years in other reconstituted wood products such as flakeboards, particleboards, and fiberboards [8,9,11,12,59-64]. Table 16 shows the laboratory decay test of low-density acetylated particleboards made from perishable albizzia wood. They were resistant to attack by Tyromyces palustris (brown rot), Coriolus versicolor (white rot), and Chaetomium globosum (soft rot) above 12% WPG. These acetylated boards with 20% WPG also exhibited an improved resistance to attack by the destructive Formosan termite, Coptotermes formosanus, in the laboratory. However, their performance was unsatisfactory in the wet tropics with a higher hazard of termite attack. High resistance to fungal and bacterial attack in acetylated southern pine and aspen flakeboards was evidenced in laboratory and fungus cellar tests [12]. 

Activated carbons manufactured in Poland by (ZEW) Carbon Electrodes Plant in Racibdrz and Plant of Destructive DistiUation of Wood (HPSDD) in Hajnowka and carbons of Chemviron (RFN) and Norit (Holand) which may be used to remove pollutants from water have been tested. 

In early December 1994, the Army completed trial bums of the dunnage incinerator using contaminated wood. Preliminary findings from EPA indicated that agent destruction standards were met. However, the trial bum did not test the incinerator s ability to bum contaminated charcoal, which could be a significant source of waste for the dunnage incinerator. According to an EPA official who oversaw the trial bum, if the Army plans to bum charcoal, an additional trial bum would be required. 

Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood, and composites, albeit with less resolution. It is a form of non-destructive testing used in many industries, including aerospace, automotive, and other sectors.
