The Serial Number of Non-woven Abrasives
Since we do not have national or industry standards about the Serial Number of Non-woven Abrasives in China. Therefore it is necessary to establish and improve the company's products Serial number system. They are follow:
1.Products Serial Number will be composed by several groups, they are divided by ¡°/¡±. The first group is product¡¯s name, it is in the form of abbreviation letters ¡°NW¡± followed by two digitals. The second group is diameter of the procudts, ?it is ¡°OD¡± followed by two digitals. The third group is the thickness(width) of products, it is ¡°W¡± followed by two digitals. After them, the two digitals are density(Ply) followed by ¡°P¡± and grit size(abrasive grams) followed by ¡°#¡±, etc.
