Rheological test methods
Our UL test facilities are offering the following rheological tests.
The reference standards used for each test method are listed in the right-hand table column.

ISO 1133-1 ISO 1133-2 ASTM D1238 |
| Melt index: Intrinsic melt mass flow rate (IMFR) | ISO 1133 |
| Melt index: Intrinsic melt volume flow rate (IMVR) | ISO 1133 |
| Melt viscosity | ISO 11443 DIN 54811* |
| Solution viscosity (with/without film) | ISO 1628-1/-4 ISO 1628-4 DIN 51562-3 |
