“…They investigated the effect of temperature (Derbyshire et al, 1997) on photodegradation rates and applied the method to the assessment of photostabilisers of wood. They also evaluated artificial weathering devices and demonstrated that they offer a consistent, reliable and precise means of determining photodegradation rates for wood (Derbyshire et al, 1995(Derbyshire et al, , 1996. The strength changes were shown to be consistent with fractographic evidence of the structural changes in wood, namely with cell delamination, development of brittleness and loss in cell wall integrity (Turkulin and Sell, 2002).…”

“…The basic physical and mechanical properties of tested species are given in Table 1. The procedures for the preparation and testing of the radial and tangential thin strips were fully reported and analyzed earlier (Derbyshire et al, 1995(Derbyshire et al, , 1996 and only a brief description is given here.…”

“…UVOD Properties of tested material as well as weathering conditions strongly affect the reliability of microtensile testing and its fi nal result. Derbyshire et al (1995Derbyshire et al ( , 1996 demonstrated that the measurement of loss of microtensile strength of thin wood strips exposed to solar radiation offers a consistent, reliable and precise means of determining photodegradation rates for wood. It was shown that artifi cial weathering regimes could provide good simulation of the effects of natural weathering, and mathematical analysis procedures were developed to characterize the strength changes observed during weathering.…”

This paper presents the effects of properties of tested material and exposure conditions on the fi nal result of testing. These include density, uniformity of ring width, number of rings and latewood portions, as well as light source, presence of water and duration of exposure. Infl uences of these parameters in testing of several softwood species after exposure to different natural and artifi cial photodegradation regimes were monitored by means of changes in microtensile properties. The main fi ndings indicate that comparisons between various species should be made taking into account average material properties, predominantly latewood portion. The fact that strength loss changes follow the same pattern during different exposure conditions indicates that there is no difference in the nature of degradation process in various weathering machines. This forms a basis for the sound comparison between the artifi cial and natural weathering regimes.

“…It has also been shown that visible light up to the violet region contributes to surface discolouration [17,18]. In addition to these visible changes in the wood surface, weathering affects the wettability of the wood surface [10,20], the surface layer strength [21][22][23], chemical composition [6,8,24,25], and microscopic structure of the wood surface [26][27][28][29].…”

Wood is a truly sustainable and aesthetically pleasant material used in indoor and outdoor applications. Every material, including wood, is expected to have long-term durability and to retain its original appearance over time. One of the major disadvantages of wood is the deterioration of its surface when exposed outdoors, known as weathering. Although weathering is primarily a surface phenomenon, it is an important issue for wood products as it affects their appearance, service life, and wood-coating performance. To encourage the use of wood as a material for joinery and other building components, the results of research into increasing the weathering resistance of wood are extremely significant. The development of weathering protection methods is of great importance to reduce the maintenance requirements for wood exposed outdoors and can have a major environmental impact. There are various methods of protecting wood surfaces against weathering. This paper provides a literature survey on the recent research results in protecting wood from weathering. The topics covered include surface treatments of wood with photostabilizers; protection with coatings; the deposition of thin film onto wood surfaces; treatments of wood with inorganic metal compounds and bio-based water repellents; the chemical modification of wood; the modification of wood and wood surfaces with thermosetting resins, furfuryl alcohol, and DMDHEU; and the thermal modification of wood.
