Description of key information

The vapour pressure of the test item has been determined to be 5.8 x 10-15 Pa at 25°C

Key value for chemical safety assessment

Additional information

The vapour pressure was determined using a vapour pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25°C. Testing was conducted using a procedure designed to be compatible with Method A4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008, in accordance with Method 104 specified in the OECD Guidelines for Testing of Chemicals, 23 March 2006.
