Cleanliness of the cleanroom is generally expressed in the number of particles contained in the unit volume of air. Therefore, the smaller the numbers of the cleanliness class, the higher the grade (less dust) of the cleanroom. For the standard of cleanliness, the U. S. Federal Standards (FS-209D E) were used generally but has been abolished when ISO14644 has been enacted (2000). However, the cleanliness class based on FS 209D is still widely used in actual cleanrooms. This expresses the fine-particulate concentration as the number of particles in 1 cubic foot (pieces/ft3). Although the standard particle size is 0.5 μm in the FS-209D standard.
Sandwich panel Is popular today The general structure consists of sheet metal such as METAL SHEET sprayed and baked with EPOXY paint or STAINLESS Sheet # 304.
