| Abstract |
As wood products emit volatile organic compounds (VOCs) and formaldehyde that are harmful to the human body, the regulation on the emission rates and the labeling as per emissions are run. The management regulations and standards for measuring the emission rates of pollutants are mainly intended for flat types. However, wood products are manufactured and used in various forms. In this study, therefore, a test method for non-flat-type wood products applicable to the small chamber method and desiccator method for measuring the emission rate of pollutants was proposed; and the emission intensity of total volatile organic compound (TVOC), toluene, and formaldehyde from the molding was analyzed. As the measuring results, when the exposed surface in the test chamber was curved, the loading factor of the specimen increased; so the difference occurred up to 33% compared to the emissions assuming that the result was flat. Through various test results, the necessity for the management of the emission rates of pollutants in the moldings was confirmed. |
