Chemical Analysis in Production Quality Control at Wood Treatment Plants
2008 - IRG/WP 08-20396
Analysis methods for quality control analysis in wood treatment plants have evolved with the changes in treatment preservative chemistries and analytical instrument technology. The basic hydrometer specific gravity measurements used for solution strength and classic wet chemistry methods for wood have given way to instrumental techniques such as X-ray fluorescence, automatic titrator, and HPLC. No...

A deflection test for monitoring decay in miniature beams
1986 - IRG/WP 2269
A laboratory apparatus for assessing decay in small stakes is described. It involves the measurement of deflection in a static bending apparatus using a displacement transducer linked to a microcomputer. Measurements are non-destructive, rapid, accurate and automatic and decay can be assessed repeatedly over long time periods....

A novel device for detecting internal defects in wooden poles
1989 - IRG/WP 2329
The diagnosis of internal defects caused by termites and decay in hardwood transmission poles has been investigated using a novel Automatic Feed Drill (AFD) pole testing device. Internal defects were recognised by changes in drill feed-rate as the automatic air-driven drill traversed its 100 mm working stroke. The instrument is portable, simple to operate and recognises defects instantaneously. Te...
