- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 5 hPa
- Remarks on result:
- other: Extrapolated value
- Conclusions:
- Vapour pressure (DIN-EN 13016-2): 5 hPa at 20 °C (extrapolated).
- Executive summary:
The vapour pressure was determined following the static method according to guideline DIN-EN 13016-2 using the "MiniVap" device (Co. Grabner-Instruments).
The vapour pressure was determined to be 5 hPa at 20°C. The value is based on 6 measurements within the temperature range of 90 °C to 115 °C.
The laboratory complied with a quality management system according to DIN EN ISO 9001 : 2008 and DIN EN ISO 14001 : 2005.
