PVC Cell Classification - ASTM D4216
 |
Purchase and download the official ASTM D4216 standard today! |
This method classifies PVC compounds based on the material's composition and select mechanical and dimensional properties. The cell classification is an eight-digit number. The minimum property value will determine the cell number even if the maximum expected value may fall within the next higher cell.
