PVC Cell Classification - ASTM D1784 Plastic Test Standard

PVC Cell Classification - ASTM D1784

This method classifies PVC compounds based on the material's composition and select properties. The cell classification is a five or six digit number. The minimum property value will determine the cell number even if the maximum expected value may fall within the next higher cell.
