MCPVT and TEVT are screening methods for testing the effects of liquid and solid chemical compounds when heated up under confinement. Special emphasis is laid on the observation of the resulting pressure build-up. As a heating unit for the MCPVT an oven is used, while for the TEVT a heating plate is installed. The temperature and pressure profiles are measured simultaneously.
The following safety characteristics are obtained by both methods:
| Characteristics | MCPVT | TEVT |
|---|---|---|
| Supplier | Fa. Kühner | self-construction* |
| Material of vessel | stainless steal | stainless steal |
| Material of sample flask | glass | glass |
| Reactor volume | 6 ml | 200 ml |
| Sample mass | ≤ 2 g | ≤ 5 g |
| Heating mode | oven | heating plate |
| Type of heating | isotherm and scan | scan |
| Heat rate | 0,6 bis 9,6 K/min | 18 K/min |
| Maximum static pressure | 190 bar | 100 bar |
| Sample rate for the temperature measurement | 1 s-1 | 1 s-1 |
| Sample rate for the pressure measurement | 1 s-1 bis 10000 s-1 | 1 s-1 bis 10000 s-1 |
