Weather testing of timber - discoloration

IRG/WP 01-20221

T Toyoda, M Azuma, Y Hikita

The brightness and color saturation of the timber were reduced over time. The perception of an increasingly dark color in the timber over time is due to the gradual reduction in brightness. The period from May to September was characterized by the greatest discoloration of all three periods of the year. Because this period has the largest number of sunlight hours, and the timber is subjected to a greater amount of sunlight. Furthermore, the period from May to September coincides with the rainy season in Japan, which adds to the discoloration.
