Why Testing the Strength of Wood Is Important in Manufacturing?

Wood is the most important and renewable source of energy which consists mainly of cellulose, hemicellulose, and lignin. Wood is an organic and a porous material. Being a natural composition of cellulose fibers embedded in lignin matrix makes wood extremely strong in tension and compression (the ability to resist compression). There are two types of wood commonly used: natural and engineered. Whereas Natural wood is harvested directly from natural growing trees, engineered wood is man made wood that has been manufactured to look like wood. It is made by binding or fixing the fibers harvested from natural wood together with adhesives such as glue. Despite the strength and stiffness that the wood holds, it is very necessary to conduct some tests on wood and timber. These tests are done in wood testing labs.

Why Testing of Wood is Done?

The use of wood is extensive in household and commercial sectors. Therefore before processing it into the final product, its strength should be analyzed. Flexure, tension and compression are the key parameters that should be focused upon while conducting a quality check. The testing enables us in analyzing the properties like performance, safety and quality of the sample in accordance with the guidelines set by the international standards. By determining the strength and deformation of the wood, it becomes easier to determine whether its fit for usage in manufacturing consumer goods such as children’s toy or a piece of furniture. Thus various tests are performed on wood in wood testing labs before carving it into the final product. For ex-the wood used in Japan should be flexible and elastic because of frequent earthquakes.

Tests assess the capability of the wood to handle stresses and strains when used in our daily life. Testing also helps the production lines to stick to pre-decided quality recommendations and helps to address the quality issues from customer’s side.

What Tests Determine the Quality of Wood?

Testing of wood is done to determine the strength of wood for various special applications. The objectives of the tests done in wood testing labs is to analyze the flexural and tensile strength, compressive strength, flexibility and grain structure of wood. Most of the wood that is used for the construction purposes (household or commercial), furniture manufacturing and other common products manufacturing industries are mechanically tested. These wooden and timber samples undergo a series of strength tests, on the basis of which its application for a particular purpose is analyzed. However, the nature of the test being conducted depends upon the purpose for which the tested sample is to be used.
