Raw Material Testing Frequencies:
| Property | Testing Method | Testing Frequency | HDPE/MDPE | LLDPE |
|---|---|---|---|---|
| Melt Flow Index (g/10 min) | ASTM D 1238 (190 C/2.16 Kg) | Once per lot | < 1.0 | < 1.0 |
| Melt Flow Index (g/10 min) | ASTM D 1238 (190 C/5.0 Kg) | Once per lot | < 2.0 | < 2.0 |
| Melt Flow Index (g/10 min) | ASTM D 1238 (190 C/21.6 Kg) | Once per lot | < 28 | < 23 |
| Density (g/cm3) | ASTM D 792 | Once per lot | > 0.932 | > 0.915 |
| Carbon Black Content | ASTM D 4218 | Once per lot | Note (2) | Note (2) |
Each roll has a unique roll number that specifies all the required information including the raw materials used. This unique number can be used to trace an individual roll from manufacturing right through to installation, and is also available on the manufacturer's warranty document, issued upon completion of a project.
