Data collection
For the laboratory test the same wood is used as at the field test. The four common wood species
The replication per species is 8, which means 32 pieces in total.
Accelerated weathering is conducted by using a weatherometer (Xenon Arc Atlas Ci35W) at the Nano Laboratory of the University of Alberta. The experiment runs over an 800 hour period, comparable to industry standards. For the radiation UV-B313 lights are used. Samples are remove every 100 hours (Magill, 2015). The color is measured with a spectrophotometer CM700 d_600d with a wavelength range from 400 – 700nm (Mamoňová, 2014).
The laboratory tests are mostly based on the publications of Magill. C. (Performance Assessment and Evaluation of Hydrophobic and Ultraviolet Protective Treatments for Historic Log Structures). 2015. and Lebow, S.T., and Anthony, R.W. (Guide for use of wood preservatives in historic structures.) 2012.
