る上でＭＬ要な要素となっている。In order to secure such a clean space, special considerations not found in ordinary buildings are required, and in terms of equipment, high-performance filters (HEPA filters) are used, and air conditioning is controlled at high ventilation rates. It will be planned. On the other hand, in terms of architecture, three elements are required: airtightness to prevent contaminants from entering, a structure with few irregularities to prevent contaminants from accumulating, and a structure that does not generate contaminants. In particular, choosing a material that generates less dust for the walls, floor, and ceiling is an important element of ML in ensuring a clean space.

The purpose of this test method is to forcibly cause the specimen to generate dust, and to determine the number of suspended particles in the space thus generated. The object of the present invention is to provide a new and useful test method that can quantitatively evaluate the dust generation properties of architectural materials.

試体の発塵性を定量的に評価することかできる。In the present invention, as described above, a specimen is placed in a space that is separated from a general Q living space and has a high degree of air cleanliness, and the surface of the specimen is made of metal or synthetic resin. By applying an external force with a brush made of aluminum, the specimen was forcibly made to generate dust, and the number of particles floating in the space was measured, so that the dust generation ability of the specimen could be quantified. It is possible to evaluate it objectively.
