Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EU Method A.4 (Vapour Pressure)
Version / remarks:
Directive 92/69/EEC, A.4.
not specified
GLP compliance:
Type of method:
effusion method: vapour pressure balance
20 °C
Vapour pressure:
< 0 hPa
Remarks on result:
other: temperature range between 20 and 150 °C

Precautionary a Different Scanning Calorimetry was done. The test substance shows an endothermic effect beginning at 160°C and an exothermic decomposition after.

In the temperature range between 19.8 °C and 150.4 °C no increase in weight and therefore no vapour pressure of the test substance was registered with the balance.

A vapour pressure value of lower than 0.00001 hPa was determined between 20 and 150 °C in a reliable study conducted according to EU method A.4.
Executive summary:

The vapour pressure of the test item was determined according to EU method A.4. and is 0.00001 hPa in the temperature range between 20 and 150 °C. No increase in weight was registered on the balance within this temperature range and therefore no increase in vapour pressure could be detected.

Description of key information

The test item has a vapour pressure of lower than 0.00001 hPa between 20 and 150 °C.

Key value for chemical safety assessment

Vapour pressure:
0 hPa
at the temperature of:
20 °C
