The log board for furniture needs to be dried, and the wood moisture content should be 8% of the annual average wood equilibrium moisture content+1% in the area where the board product is located.
Although only professional instruments can accurately measure the moisture content of the board, the moisture content of the wood can be described as' indistinguishable' if it only passes the appearance inspection. In fact, there are some tips to help you determine whether the moisture content of wood is qualified. Generally speaking, the characteristics of dry wood are obvious:
Compared with the wood that has not been dried, the weight of the wood is obviously reduced, the feel is warm, the knocking sound is crisp, the shavings are hot when pushing and planing, and the planing surface is smooth. Wood with high moisture content is heavy, cold to the touch, not brittle to push, and there is no water even for shavings, so this kind of wood cannot be used.

Standards have played a great role in economic development. Since the implementation of 1989 in China, Standardization Law has played an important role in improving product quality and promoting the development of economic and social sciences. However, with the progress of society and the improvement of consumer demand, higher requirements are put forward for product quality. The revision of the standard has alleviated the contradiction between supply and demand caused by product quality to a certain extent, and solved this contradiction through mandatory methods. Therefore, standard setting is very important, and standard revision is even more important.
