Executive summary:

A study was performed to determine the vapour pressure of the test substance. The method followed is amongst those described in the Annex to EEC Directive 92/69/EEC (Method A4) and the OECD Guidelines for the Testing of Chemicals (Method 104). 

The vapour pressure of test item was determined to be 6 E-6 Pa at 25ºC.

Description of key information

The vapour pressure was determined using a vapour pressure balance in accordance with EEC Method A4 and OECD Method 104.

The vapour pressure of test item was determined to be 6 E-6 Pa at 25ºC.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
